XPARTCO 00631633 Range Surface Burner Igniter Electrode
The XPARTCO 00631633 is an aftermarket replacement gas range surface burner igniter electrode (also called a spark electrode) compatible with select Bosch, Thermador, and Gaggenau gas ranges and cooktops in the HDI, HGI, NGM, NGMP, HDIP, and HGIP series. The surface burner igniter electrode is the ceramic-tipped spark generator located at each gas burner position on the cooktop. When the burner is turned on, the ignition system sends a high-voltage pulse to the electrode, which generates a spark across the ceramic tip to ignite the gas flowing from the burner. When the electrode cracks, chips, or becomes contaminated with grease or food residue, the burner may fail to light, click continuously without igniting, or spark intermittently.
This replacement electrode is constructed from high-quality ceramic and metal — the ceramic insulator body withstands the thermal cycling of repeated ignition, while the metal spark tip maintains reliable spark gap geometry over time. Sold individually — one electrode per order. It directly replaces AP5950372, 4162041, and PS10057850. Because a gas range typically has four or more burners with individual electrodes, compare your existing electrode's dimensions and mounting configuration before ordering to ensure a correct fit. Installs in minutes — no tools required in most cases.

Installation Notes
⚠️ Gas Appliance Safety Warning This part is used in gas ranges. Always turn off the gas supply at the shutoff valve and unplug the range from the electrical outlet before beginning any repair. If you smell gas at any point during or after installation, leave the area immediately and contact your gas utility provider. If you are not confident working on gas appliances, have this part installed by a qualified appliance technician.
⚠️ Unplug Range and Turn Off Gas Before Starting With the range unplugged and gas supply off, remove the cooktop grates and burner caps to access the burner heads. The igniter electrode is the small ceramic component positioned beside each burner head, held in place by a mounting bracket and screw or a snap-in clip depending on the model. Disconnect the single wire connector from the old electrode. Remove the mounting screw and lift the old electrode out. Install the new 00631633 electrode in the same position, secure the mounting screw, and reconnect the wire connector. Replace the burner caps and grates. Restore power and gas supply, then test each burner for reliable ignition. If the burner still does not light after replacing the electrode, inspect the igniter wire and the electronic ignition module. Tools needed: Phillips or Torx screwdriver (for mounting bracket on some models); no tools needed on models with snap-in electrodes.
Frequently Asked Questions
What does the surface burner igniter electrode do?
The igniter electrode is the component that creates the spark to light each gas burner. When you turn a burner knob past the "lite" position, the range's electronic ignition module sends a series of high-voltage pulses through the igniter wiring to the electrode at that burner. The electrode generates a visible spark across its ceramic tip to the grounded burner cap or burner head, and that spark ignites the gas flowing from the burner ports. Each burner position has its own dedicated electrode — failure of one electrode affects only that burner, while other burners on the same range continue to work normally.
My burner clicks constantly even when turned off — is it the electrode?
Constant clicking when a burner is in the off position is almost always caused by moisture or food residue in the igniter system rather than a failed electrode. When liquid boilover or steam gets into the burner cap area or electrode housing, it can cause the ignition module to fire continuously. Remove the burner cap and grate from the affected burner and allow everything to dry thoroughly — an hour in a warm oven (electric only, turned off) can help. Wipe the electrode tip clean with a dry cloth. If clicking persists after the components are completely dry and clean, the electrode or the ignition module may have been damaged by the moisture and needs replacement.
How many electrodes do I need for my Bosch range?
Most Bosch gas ranges have four surface burners, each with its own dedicated igniter electrode — so a full cooktop replacement typically requires four electrodes. This listing is for one electrode. If only one burner is not lighting, you likely only need one replacement. If multiple burners are failing, order one electrode for each affected burner. Because the electrodes on compatible Bosch models use the same part number across all burner positions, one order of multiple quantities covers all positions.
Can I clean the electrode instead of replacing it?
Yes — a contaminated or greasy electrode can often be cleaned successfully rather than replaced. Remove the electrode from the burner area and gently clean the ceramic tip and metal contact with a dry cloth or a soft toothbrush. Do not use water or liquid cleaners directly on the electrode — moisture in the ceramic can cause persistent clicking. If the ceramic body is cracked or the metal tip is corroded or missing, replacement is required. If the ceramic is intact and clean but the spark is still weak or absent, the electrode's spark gap geometry may have changed from thermal expansion and a replacement is the better fix.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Bosch OEM part, but is manufactured from high-quality ceramic and metal to match the dimensions and spark performance of the original 00631633 igniter electrode.

XPARTCO XP6974 Dryer Thermostat Kit Replaces WP3387134, WP3392519, W10900067, 279816
The XPARTCO XP6974 is an aftermarket dryer thermostat kit containing four thermal components for Whirlpool-family electric and gas dryers including Whirlpool, Kenmore, Maytag, Amana, KitchenAid, Roper, Admiral, Estate, Crosley, Inglis, and Magic Chef. The kit includes the cycling thermostat (WP3387134), thermal fuse (WP3392519), high-limit thermostat and thermal cut-off kit (279816 / W10900067) — the complete set of heat-sensing and safety components that regulate dryer temperature and prevent dangerous overheating.
These four components work together to control and protect the dryer's heating system. When any one of them fails, the dryer may produce no heat, overheat, run too long, or stop mid-cycle. Because a failed thermal fuse is almost always caused by an underlying overheating condition that also stresses the other components, replacing all four together in a single repair is the recommended approach. Includes all wiring hardware needed for installation. Installs in 20–30 minutes with basic hand tools.
Quick Answer
The XPARTCO XP6974 Dryer Thermostat Kit fixes Whirlpool-family dryers that produce no heat, overheat, take too long to dry, or stop mid-cycle. Includes all four thermal components: cycling thermostat (L155-25), thermal fuse (196°F), high-limit thermostat (L250-80), and thermal cut-off (309°F). Compatible with Whirlpool, Kenmore, Maytag, Amana, KitchenAid, Roper, Admiral, Estate, Crosley, Inglis, and Magic Chef electric and gas dryers.
Common Problems This Kit Fixes
Dryer produces no heat — thermal fuse or high-limit thermostat has blown

Installation Notes
⚠️ Unplug Dryer and Shut Off Gas Before Starting Disconnect power (and shut off gas for gas dryers) before beginning. Remove the back panel of the dryer to access the heating element housing and exhaust duct. The thermal fuse (WP3392519) and cycling thermostat (WP3387134) are located on the exhaust duct or blower housing — disconnect the wires, unscrew the mounting screws, and install the new parts in the same positions. The high-limit thermostat and thermal cut-off (279816 kit) are located on the heating element housing — disconnect the wires and unscrew the mounting screws to remove the old parts and install the new ones. Reconnect all wires to the correct terminals — take a photo before disconnecting to reference during reinstallation. Reassemble the back panel, restore power, and run a test cycle to verify heat. Tip: Before running the dryer, also clean the full length of the exhaust duct — a clogged vent is the most common root cause of dryer overheating and repeated thermal fuse failures. Tools needed: Phillips screwdriver, 1/4" nut driver, needle-nose pliers.
Frequently Asked Questions
What does each part in this kit do?
The cycling thermostat (WP3387134) monitors the air temperature in the exhaust duct and cycles the heating element on and off to maintain the correct drying temperature — it is the part that controls how hot the dryer gets during normal operation. The thermal fuse (WP3392519) is a one-time safety device that permanently cuts power to the heating element if the dryer overheats above 196°F — it is the most common cause of no-heat in Whirlpool-family dryers. The high-limit thermostat opens at approximately 250°F to cut heating element power if temperature gets too high, and resets automatically when it cools. The thermal cut-off is a backup one-time fuse on the heating element that opens at 309°F if the high-limit thermostat fails to protect the heater.
Why should I replace all four parts instead of just the one that failed?
When a thermal fuse blows, it almost always blew because the dryer overheated — and that overheating event put significant stress on all the other thermal components as well. A failing cycling thermostat is the most common cause of repeated thermal fuse failures: if the cycling thermostat stops regulating temperature correctly, the dryer runs too hot, the high-limit thermostat is repeatedly stressed, and the thermal fuse eventually blows. Replacing just the fuse without replacing the cycling thermostat means the same overheating will blow the new fuse. Replacing all four parts at once eliminates that risk in a single repair.
How do I test these parts with a multimeter?
Set the multimeter to continuity or resistance mode. The thermal fuse (WP3392519), cycling thermostat (WP3387134), and high-limit thermostat should all show closed continuity (near-zero resistance) at room temperature. The thermal cut-off should also show closed continuity at room temperature. Any part that reads open (no continuity / infinite resistance) at room temperature has failed and needs to be replaced. A blown thermal fuse or cut-off will always read open — they are one-time devices and cannot reset.
What causes the thermal fuse to blow repeatedly?
The most common cause by far is a clogged exhaust vent — lint accumulation inside the dryer duct restricts airflow, causing heat to build up inside the dryer cabinet until the thermal fuse trips. Always clean the full length of the exhaust duct before and after replacing these parts. Other causes include a failing cycling thermostat that is not regulating temperature correctly, a stuck heating element relay, or a dryer placed in an enclosed space without adequate ventilation.
Is this kit compatible with both electric and gas dryers?
Yes — the XP6974 kit is compatible with both electric and gas Whirlpool-family dryers. Both types use the same cycling thermostat (WP3387134) and thermal fuse (WP3392519). The high-limit thermostat and thermal cut-off (279816 kit) are located on the heating element in electric models and on the burner assembly area in gas models. Always verify your specific model number before ordering to confirm all four parts apply to your dryer.

XPARTCO 3406107 Dryer Door Switch Replaces WP3406107
The XPARTCO 3406107 is an aftermarket replacement door switch for Whirlpool, Kenmore, Maytag, and KitchenAid dryers. Mounted inside the upper corner of the front panel, this safety switch has a spring-loaded black tab that gets pressed in when the door closes. That contact tells the control board the door is shut, which is required before the dryer will start, and it also powers the interior drum light. Over time the switch's internal contacts wear out or the tab loses spring tension, and the dryer either won't start at all or runs with the door open — a safety condition the switch is specifically designed to prevent.
This is a three-wire SPDT (single pole, double throw) switch built to the same dimensions and mounting points as the original, and it's designed to remain compatible with older two-wire harnesses as well. Direct-fit aftermarket replacement, no wiring modifications needed.
Quick Answer
The XPARTCO 3406107 Dryer Door Switch fixes a dryer that won't start, runs with the door open, or has a dead interior light. Direct-fit replacement for OEM WP3406107. Classic symptom: pressing start does nothing until you push and hold the door shut, or the drum light never comes on.
Common Problems This Part Fixes
Dryer won't start even though the door is closed
Dryer runs with the door open (safety switch failure)
Interior drum light doesn't turn on
Door doesn't seem to latch or seal properly against the switch tab
Drum doesn't spin, or cycle stops intermittently
Touchpad or start button appears unresponsive
Cross Reference Information
Part numbers can change over a product's lifecycle as manufacturers update designs or release new appliance models. For your convenience, we've included any known superseded, alternate, or cross-reference part numbers that match this item.
Replaces Part Numbers
This door switch directly replaces the following part numbers:
WP3406107, WPW10569603, 3406107, 3406109, W10569603, 3405100, 3405101, 3406100, 3406101, ES6107, 528948, 11259-65, PD00002378, EAP11741701, AP6008561, AWP47183, PS11741701
This switch design was updated to a three-wire configuration at some point in its production history (superseding older 3405100/3405101/3406100/3406101 numbers), but the current three-wire version remains compatible with older two-wire harnesses, so it's a safe direct replacement across all of these part numbers.

Installation Notes
⚠️ Unplug Power Before Installing Unplug the dryer or switch off its circuit breaker before beginning. The switch is mounted inside the upper corner of the front panel, so you'll need to remove the front panel or top panel per your model's service guide to access it. Disconnect the wire connector from the old switch, then remove the mounting screw(s) holding it in place. Install the new switch in the same position, reconnect the wire connector, and reinstall the panel. Before closing everything up, you can test the switch by pressing the black tab — you should feel spring resistance and hear or feel a distinct click. Restore power and confirm the dryer starts normally with the door closed and stops when the door is opened.
Frequently Asked Questions
My dryer won't start — is this the part I need?
This is one of the most common causes of a dryer that won't start even with the door closed. Try pressing the black tab on the switch by hand — if it feels loose, doesn't click, or offers no resistance, the switch has likely failed and needs replacement.
My dryer runs even with the door open — is that dangerous?
Yes, this indicates the door safety switch has failed in a way that no longer prevents operation with the door open, which is a safety hazard. Replace the switch promptly and avoid running the dryer with the door open in the meantime.
My dryer has a two-wire connector — will this three-wire switch still work?
Yes. This switch was redesigned to a three-wire configuration but remains compatible with older two-wire wiring harnesses, so it's a safe direct replacement regardless of which wire configuration your dryer currently has.
Does this switch also control the interior light?
Yes. This switch serves a dual function — it's the safety interlock that permits the dryer to run only with the door closed, and it also powers the interior drum light when the door is open.

XPARTCO 8557403 Dryer High-Limit Thermostat with Thermistor Replaces WP8557403
The XPARTCO 8557403 is an aftermarket replacement dryer high-limit thermostat and thermistor sensor assembly compatible with a wide range of Whirlpool, Maytag, Kenmore, Amana, KitchenAid, Jenn-Air, Roper, Admiral, Norge, and Magic Chef electric dryers — including the Whirlpool Duet and Maytag MED series. This single component combines two functions: the high-limit thermostat (rated L146-44C, opens at 295°F) acts as a resettable safety switch that cuts power to the heating element if the dryer air temperature exceeds safe limits, and the integrated 50-ohm thermistor continuously monitors air temperature and sends resistance-based readings to the control board to regulate the drying cycle.
When this part fails — whether the thermostat opens permanently or the thermistor provides incorrect temperature data — the dryer may produce no heat, run too hot, take too long to dry, overheat, or display temperature-related error codes. It measures 1-5/8"L x 1-5/8"W x 2"H with approximately 1-5/8" between mounting holes and is constructed from black/gray plastic and metal.

Installation Notes
⚠️ Unplug Dryer Before Starting — Electric Dryers Only Disconnect power before beginning. The 8557403 thermostat/thermistor assembly is typically located on the heating element housing or duct inside the dryer — access it by removing the back panel. On Whirlpool Duet and Maytag front-load-style dryers, the component may be accessible by removing the lower front panel. Photograph all wire connections before disconnecting — the thermistor wires and thermostat wires must be reconnected to the correct terminals. Remove the two mounting screws and pull the old assembly off. Note the position and orientation before removing. Install the new 8557403 assembly in the same position and orientation, reconnect all wires, and reinstall the mounting screws and panel. Restore power and run a test heat cycle to confirm normal operation. Tools needed: Phillips screwdriver, 1/4" nut driver.
Frequently Asked Questions
What makes this part unusual — why does it combine a thermostat and a thermistor?
The WP8557403 is a combined assembly used on newer Whirlpool Duet and Maytag MED series dryers that use electronic temperature control rather than purely mechanical thermostats. The high-limit thermostat (L146-44C) provides the traditional safety function — it opens the circuit if dryer temperature exceeds 295°F. The integrated NTC thermistor continuously reports resistance-based temperature data to the electronic control board, which uses the data to regulate the heating element and control cycle timing. Both functions are built into a single compact housing, making this a unique part that replaces what older dryers used to handle with separate components.
How do I test the thermostat and thermistor?
Set your multimeter to continuity or resistance mode. For the thermostat portion: probe the thermostat terminals — at room temperature, a working thermostat shows closed continuity (near-zero resistance). An open circuit at room temperature confirms the thermostat has failed. For the thermistor portion: probe the thermistor terminals — at room temperature (approximately 25°C/77°F), a working 50-ohm NTC thermistor should read approximately 50 ohms. A reading of zero ohms (shorted) or open circuit (no continuity) confirms the thermistor has failed. Either failure mode warrants replacing the complete 8557403 assembly.
What is the difference between 8557403 and WP8557403?
These are the same part. WP8557403 is the updated Whirlpool OEM part number that superseded the original 8557403. The 1180102 is also a cross-reference for this same assembly. This aftermarket replacement is compatible with all of these numbers.
Do I also need to replace the thermal fuse or cycling thermostat?
The 8557403 replaces the high-limit thermostat and thermistor mounted on the heating element housing area. The exhaust duct thermal fuse (WP3392519 on most Whirlpool-family dryers) and cycling thermostat (WP3387134) are separate components located on the exhaust duct and are not included in or replaced by the 8557403. If your dryer has no heat, test all thermal components before ordering — check the 8557403 assembly, the thermal fuse, and the cycling thermostat, then order only what has failed. If an overheating event caused the high-limit to fail, the other thermal components may be stressed as well.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Whirlpool OEM part, but is manufactured from plastic and metal with an L146-44C thermostat and 50-ohm NTC thermistor to match the specifications and performance of the original WP8557403 assembly.

XPARTCO DC47-00018A Dryer Hi Limit Thermostat
The XPARTCO DC47-00018A is an aftermarket replacement cycling high-limit thermostat for Samsung and select Kenmore electric dryers. This is a genuine, automatically resetting thermostat — not a one-time fuse. It monitors temperature in the heating circuit and opens to cut power to the heating element at approximately 260°F, protecting the dryer from overheating. Once the temperature drops to around 210°F, it closes again on its own, letting the dryer resume heating without any part replacement needed.
This thermostat works alongside a downstream thermal fuse (such as our DC96-00887C listing) in the same overheat-protection circuit. If this thermostat is cycling excessively, tripping prematurely, or failing to regulate temperature correctly, it can put stress on that thermal fuse, sometimes causing it to blow as a last-resort safety measure. Symptoms of a failing high-limit thermostat include no heat or insufficient heat, drying that takes too long, or the dryer shutting off too soon before a load is fully dry. It directly replaces 35001092, WP35001092, 1122485, AP4201898, PS4205217, EAP2430930, PS2430930, and AP6008682.
Quick Answer
The XPARTCO DC47-00018A Dryer Hi Limit Thermostat fixes Samsung and select Kenmore electric dryers with no heat or insufficient heat, drying that takes too long, or premature shutoff before a load is fully dry. Opens at approximately 260°F, resets automatically around 210°F. Replaces 35001092, WP35001092, 1122485, AP4201898, PS4205217, EAP2430930, PS2430930, AP6008682. This is a resettable thermostat, not a fuse — it does not need replacement after each trip. It's a different component from our DC96-00887C thermal fuse listing, though the two are often checked together.
Common Problems This Part Fixes
Dryer has no heat or insufficient heat
Drying takes too long to complete a cycle
Dryer shuts off too soon, before clothes are fully dry
Timer will not advance through the cycle
Dryer that stopped working suddenly after running unusually hot
Dryer with a history of repeated downstream thermal fuse failures

Installation Notes
⚠️ Unplug Dryer Before Starting Disconnect power at the outlet or shut off the circuit breaker before beginning. Wear work gloves. Access is typically through the rear panel, near the heater duct and blower housing area where this thermostat is mounted. Photograph the wiring connections before disconnecting anything, since this thermostat can be positioned close to other similar-looking components in the same circuit. Remove the old thermostat from its mounting position, noting orientation, and disconnect its wiring. Install the new DC47-00018A in the same position, reconnecting wiring exactly as photographed. Reassemble the panel, restore power, and run a full test cycle to confirm normal, consistent heating with no premature shutoffs. Tools needed: Phillips or nut driver (model-dependent), work gloves.
Frequently Asked Questions
Do I need to reset this thermostat after it trips, or replace it?
Neither, in normal operation — this is a genuine cycling thermostat that resets itself automatically once the dryer cools to around 210°F. You should only need to replace it if it has failed outright (stuck open, stuck closed, or no longer switching at the correct temperatures), not simply because it tripped once during normal operation.
My dryer shuts off before the load is fully dry. Is that this part?
It's a strong possibility. If this high-limit thermostat is tripping prematurely — opening at a lower temperature than it should — the dryer can cut heat and end the cycle early even though the load isn't actually dry yet. This is one of the more common symptoms this thermostat addresses.
My thermal fuse keeps blowing. Could this thermostat be the underlying cause?
Yes, this is worth investigating. This thermostat and the downstream thermal fuse (our DC96-00887C listing) protect the same circuit at different points. If this thermostat isn't regulating temperature correctly — cycling excessively or failing to catch a temperature spike — the thermal fuse can end up blowing repeatedly as the last line of defense. If you've replaced the fuse more than once, checking or replacing this thermostat at the same time is a reasonable next step.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Samsung OEM part, but is manufactured to match the electrical specifications and opening/reset temperatures of the original DC47-00018A high-limit thermostat used in compatible Samsung and Kenmore electric dryers.

Installation Notes
⚠️ Unplug Power Before Installing Unplug the dryer before beginning, and shut off the gas supply first on gas models. Wear work gloves, as internal parts and cabinet edges can be sharp. Remove the top and front panel as shown in your model's service guide, then slide the drum out, which is easier with a second person. Remove the old belt and route the new belt around the drum, the tension pulley, and the motor pulley as the old one ran, then reassemble in reverse order. Check the tension pulley and drum rollers while the drum is out and replace any that are worn.
Frequently Asked Questions
My dryer runs but the drum won't turn. Is this the part I need?
That is the classic sign of a broken drum belt. If the motor runs and you can turn the drum freely by hand, check the belt first.
How long is this belt?
It is approximately 89-1/2 inches long, with four ribs. Small differences are normal, but if your old belt is a very different length, check your model number before ordering.
Should I replace anything else while the drum is out?
Inspect the tension pulley and the drum rollers or glides. These wear along with the belt, and they are much easier to replace now than later.
Will this fit my dryer?
It is listed for hundreds of GE, Hotpoint, and Kenmore dryers, but the model list above is only a sample. Check your model number against your parts diagram, or contact our support team and we'll verify it before you order.

AGM30045804 Genuine OEM LG Dryer Thermistor and Thermostat Kit
The AGM30045804 is a genuine LG OEM high-limit thermostat and thermistor kit for LG dryers. These two components work together in the same temperature-regulation circuit: the thermistor is a temperature sensor, mounted in the blower housing with its wire harness included, that continuously reports drum temperature to the control board so it can fine-tune heat output throughout the cycle. The high-limit thermostat is a safety switch that automatically shuts off the heating element if temperatures climb past a safe threshold, then resets itself once the dryer cools, without needing to be replaced the way a thermal fuse does.
Because these two parts share the same circuit and tend to wear or fail around a similar timeline, LG sells and services them together as one kit rather than as separate individual parts. Symptoms of failure in this circuit include the dryer overheating (which can scorch clothing or, left unaddressed, pose a fire risk), the dryer running with little or no heat, drying times that have become inconsistent, an error code related to temperature control on the display, or clothes coming out damp after a full cycle. It directly replaces 6931EL3003C, 6323EL2001B, 6931EL3003F, 6931EL3004B, AP7206815, EAP16732335, and PS16732335.
Quick Answer

Installation Notes
⚠️ Unplug Dryer Before Starting — Let It Cool Fully First Disconnect power at the outlet or shut off the circuit breaker before beginning, and allow the dryer to cool completely if it was recently run. Wear work gloves. Access on many LG models follows this general sequence: remove the lint screen, then remove the two front panel screws underneath it, the two screws on the face of the panel, and the two screws holding the blower cover in place. Disconnect the door switch connector and remove the front panel. With the front open, release the drive belt from the tensioner and remove the drum to access the blower housing where the thermistor is located. Photograph the wiring connections before disconnecting anything, since the thermistor and high-limit thermostat can be easy to confuse with other similar-looking components nearby. Disconnect and remove the old thermistor and high-limit thermostat, noting their exact mounting positions. Install the new components from this kit in the same positions, reconnecting wiring exactly as photographed. Reinstall the drum, re-tension the belt over the tensioner, and reassemble the front panel, blower cover, and lint screen area in reverse order. Restore power and run a full test cycle to confirm normal, consistent heating with no premature shutoffs. Tools needed: Phillips screwdriver, nut driver, work gloves.
Frequently Asked Questions
I already replaced the high-limit thermostat, but it keeps tripping. Why would I need this kit instead?
This is a well-documented pattern. If the thermistor — the sensor that reports temperature to the control board — is misreading heat, the control can keep driving the heating element past the point where the high-limit thermostat has to trip repeatedly to protect the dryer, even with a brand-new thermostat installed. Replacing the thermistor alongside the thermostat addresses the root cause rather than just the symptom, which is exactly why LG packages them together as one kit.
What's the difference between the thermistor and the high-limit thermostat?
The thermistor is a sensor, not a switch — it's a variable resistor whose resistance changes with temperature, and the control board reads that value continuously to regulate heat output throughout the cycle. The high-limit thermostat is a safety switch that does one job: it shuts off the heating element automatically if temperature exceeds a safe limit, then resets itself once things cool down. A failing thermistor causes inconsistent or inaccurate heat regulation; a failing high-limit thermostat causes the dryer to shut off unexpectedly or fail to protect against overheating.
My parts diagram shows more thermostat-like parts than what's in this kit. Did I order the wrong thing?
Not necessarily — some LG dryer models have additional related components, such as a separate blower thermostat, that are not part of this specific kit. This kit covers the high-limit thermostat and thermistor. If your repair calls for additional related parts, or if you're not sure exactly which components your model needs, contact our support team with your model number and we'll help you confirm the complete parts list before you order.

XPARTCO 3406105 Dryer Door Switch Replaces WP3406105
The XPARTCO 3406105 is an aftermarket replacement dryer door switch assembly compatible with a wide range of Whirlpool-family dryers including Whirlpool, Kenmore, Maytag, KitchenAid, Amana, Roper, Estate, Crosley, Inglis, Admiral, Jenn-Air, Magic Chef, and Norge. The door switch is a safety component mounted inside the dryer cabinet near the door opening. When the door is closed, the door strike depresses the switch actuator, completing the circuit and allowing the dryer to start and run. When the door is opened, the switch opens the circuit and stops the dryer. On models with a broken belt detection circuit, the door switch also plays a role in belt failure detection. A failed door switch causes the dryer to either not start at all or to run continuously with the door open.
This is a Single Pole, Double Throw (SPDT) 3-wire switch with stainless steel terminals and a heat-resistant housing. It measures 1-3/4" L x 1-5/8" W x 1-1/4" H with a 7-3/4" wiring harness. Electrical specs are 120-240V, 50-60Hz, 11A, 1/3HP. The kit includes the switch and 3-wire harness assembly. It directly replaces WP3406105, 3406104, 3405104, 3405105, 528947, AP6008560, and several additional cross-reference numbers. Installs in 15–30 minutes with basic hand tools.

Installation Notes
⚠️ Unplug Dryer Before Starting Disconnect power (and shut off gas for gas dryers) before beginning. The door switch is located inside the dryer cabinet near the door opening, typically mounted in the front panel or top panel. Access it by inserting a putty knife under the top panel to release the spring clips and lift the top, then release the front panel. Locate the old door switch — it is a small rectangular component with a spring-loaded actuator button. Photograph the wiring connections before disconnecting. Disconnect the 3-wire harness from the old switch. Release the switch from its mounting bracket by pressing the retaining tabs and pulling the switch free, or unscrewing the mounting screw. Snap the new 3406105 switch into the mounting bracket and reconnect the 3-wire harness in the same positions. Reassemble the front and top panels, restore power, and run a test cycle to confirm the dryer starts, stops when the door is opened, and runs normally. Tools needed: Phillips screwdriver, putty knife.
Frequently Asked Questions
What does the dryer door switch do?
The door switch is a safety component that monitors whether the dryer door is open or closed. When the door is closed, the door strike depresses the switch actuator, completing the electrical circuit and signaling the control board that it is safe to run. When the door is opened, the actuator releases, opening the circuit and stopping the dryer immediately. On many Whirlpool-family dryers, the 3-wire SPDT switch also provides a secondary circuit used for broken belt detection — one of the switch's contacts is part of the motor start circuit, while the other is part of a safety cutoff circuit.
How do I test the door switch with a multimeter?
Unplug the dryer and disconnect the switch from the harness. Set your multimeter to continuity mode. The 3406105 is an SPDT switch with three terminals — typically labeled Common (C), Normally Open (NO), and Normally Closed (NC). With the actuator button not pressed (door open position), you should read continuity between C and NC, and no continuity between C and NO. With the actuator button pressed (door closed position), you should read continuity between C and NO, and no continuity between C and NC. Any deviation from this pattern confirms the switch has failed.
What is the difference between 3406105 and 3406104?
The 3406104 was the original part number, and the 3406105 (later updated to WP3406105) is the current replacement that superseded it. They are the same door switch and are fully interchangeable. The 3405104 and 3405105 are also cross-references for this same switch from earlier production. If your dryer's documentation or old switch label shows any of these numbers, the 3406105 is the correct current replacement.
Why does this switch have 3 wires when my old switch only had 2?
The WP3406105 is an SPDT (Single Pole, Double Throw) switch with 3 terminals — Common, Normally Open, and Normally Closed. Some older dryer models used a simpler 2-wire switch, but the 3-wire WP3406105 is the updated replacement that works on both older and newer models. On models that originally had a 2-wire switch, only two of the three terminals are used — the third is simply left unconnected. Follow your model's wiring diagram or take a photo of the original switch's wire connections before removing it.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Whirlpool OEM part, but is manufactured from durable plastic and metal with stainless steel terminals to match the dimensions and electrical specifications of the original WP3406105 door switch assembly.
