XPARTCO EXP497 Microwave Door Switch (Normally Open)
The XPARTCO EXP497 is an aftermarket replacement Normally Open (NO) microwave door interlock switch compatible with a wide range of GE, Whirlpool, Samsung, LG, Frigidaire, Kenmore, Panasonic, and Sharp microwaves. The door interlock switch is one of several safety switches in the microwave door system. It allows the microwave to operate only when the door is fully closed — when the door closes, the switch is mechanically activated, completing the circuit and signaling the control board that it's safe for the magnetron to fire. When the door is open, the switch is released and the circuit is broken, preventing the microwave from generating microwave radiation.
This switch is rated for 16A at 125/250V AC, giving it the heavy-load capacity required for microwave door safety circuits. It directly replaces an extensive list of cross-reference part numbers from multiple manufacturers, including 3B73362F, SZM-V16-FA-63, WB24X816, WB24X829, WB24X10180, 6600W1K003C, WP56001036, 5304408938, AP4437957, PS3522738, and dozens more. Important: confirm your original switch is a Normally Open (NO) type before ordering — this part will not replace Normally Closed (NC) or COM-style switches. Installs in 15–25 minutes with basic hand tools.

Installation Notes
⚠️ High-Voltage Safety Warning — Microwave Capacitor Microwaves contain a high-voltage capacitor that can hold a lethal electrical charge even after the appliance is unplugged. Before opening the microwave cabinet to access the door switches, always unplug the unit and discharge the high-voltage capacitor using proper safety procedure (with an insulated screwdriver across the capacitor terminals while wearing insulated gloves). If you are not familiar with safely discharging a microwave capacitor, have this repair done by a qualified technician.
⚠️ Wear Work Gloves — Identify Switch Position Before Removing Disconnect power before beginning. Wear work gloves to protect your hands. After safely discharging the high-voltage capacitor, remove the microwave's outer cabinet or control panel as needed to access the door interlock switch assembly — typically located behind the right side of the door frame on most microwaves. Take a photo of all switch positions and wire connections before disconnecting anything. Microwaves usually have 2–3 switches in the door interlock assembly: confirm which one is the Normally Open switch (the EXP497 fits this position only). Disconnect the wires from the old switch — make a note of which wire goes where. Release the switch from its mounting tabs and pull it free. Install the new EXP497 in the same position with the same wire connections. Reassemble the cabinet, restore power, and test the microwave by closing the door and confirming it starts and heats normally, then opening the door and confirming it shuts off immediately. Tools needed: Phillips screwdriver, work gloves, insulated tools (for capacitor discharge).
Frequently Asked Questions
What's the difference between a Normally Open and Normally Closed microwave door switch?
Microwave door interlock systems use both types together to provide redundant safety. A Normally Open (NO) switch — like the EXP497 — has open contacts at rest; when the door closes and pushes the switch button, the contacts close to complete a circuit, signaling "door closed." A Normally Closed (NC) switch is the opposite — contacts are closed at rest and open when the door pushes the button. Most microwaves use one or more of each type wired together so the control system can confirm the door is genuinely closed from multiple inputs. They are not interchangeable — you must replace each switch with the same type. If your switch is NC, order the EXP499 instead.
How do I know if I need the Normally Open or Normally Closed switch?
The easiest way is to read the part number printed on the side of the failed switch and compare it to the cross-reference lists for the EXP497 (Normally Open) versus the EXP499 (Normally Closed). If the markings are unreadable, you can also test the switch with a multimeter set to continuity mode: with the switch at rest (button released), a Normally Open switch reads open (no continuity) and a Normally Closed switch reads closed (continuity). Replacing each switch with the same type is essential — installing the wrong type can prevent the microwave from starting or create unsafe conditions.
My microwave runs but doesn't heat — could this be the door switch?
Yes — this is one of the most recognizable symptoms of a failed door switch in a multi-switch interlock system. A microwave that turns on (light, fan, turntable) but does not heat often has a failed door switch in one of the door positions while the others continue to work. The control system may allow the auxiliary components to run but blocks the magnetron from firing without confirmation from all switches. Check all door switches systematically — one Amazon review noted a customer needed three identical switches to fully repair their microwave because the third switch (at the top of the door) was the actual cause of the no-heat condition. Replacing all door switches together is a common approach.
My microwave keeps running with the door open — what should I do?
This is a serious safety concern. Disconnect power to the microwave immediately and do not use it until the door switch is replaced. A microwave that continues to run with the door open exposes you to microwave radiation, which can cause serious injury. This usually indicates one or more door switches are stuck in the "door closed" position. Replace the failed switches with matching NO or NC type (EXP497 for NO, EXP499 for NC) before using the microwave again.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a manufacturer-branded OEM switch from any single brand, but is manufactured to match the dimensions, contact configuration, and 16A/125-250V AC rating of the dozens of OEM door switches it cross-references across multiple appliance brands.

6324W1A001L Genuine LG OEM Microwave Magnetron
The 6324W1A001L is a genuine LG OEM magnetron for microwave ovens and microwave/oven combination units. The magnetron is the component that actually generates the microwave energy used to cook and heat food — it converts high-voltage electrical power into microwave-frequency radiation, which is then directed into the oven cavity by the waveguide to agitate water molecules in your food and produce heat. Without a functioning magnetron, every other part of the microwave can work perfectly — the turntable spins, the display counts down, the fan runs — while the food inside never actually heats up.
This is a genuine LG-manufactured magnetron used not only in LG microwaves but also, under LG's role as a shared component supplier, in microwaves sold under Frigidaire, Whirlpool, Kenmore, GE, Jenn-Air, Thermador, KitchenAid, Panasonic, Goldstar, Crosley, Gaggenau, Amana, and Bosch branding. Measuring approximately 4.5"L x 4.25"W x 5"H. A failed magnetron produces a distinct symptom: the microwave runs normally in every other respect — it powers on, the turntable turns, the timer counts down — but the food inside stays cold. Sparking or arcing behind the waveguide cover, visible burn marks on the magnetron, or a burning smell are also signs of magnetron failure or damage. It directly replaces 6324W1A001A, 6324W1A001B, 6324W1A001E, 6324W1A001H, 6324W1A001Y, AGF76878403, AP4457332, EAS42812905, EAS42812906, EAS42812937, PS3529034, and 1268208.
Quick Answer
The 6324W1A001L Genuine LG OEM Microwave Magnetron fixes microwaves and microwave/oven combos that run normally — turntable spins, display works, timer counts down — but the food never actually heats up.

Installation Notes
⚠️ Danger — Microwave High-Voltage Capacitor Unplug the microwave before beginning any work. Microwaves contain a high-voltage capacitor that can store a dangerous, potentially lethal electrical charge even after the unit has been unplugged. Before opening the cabinet or touching any internal component, discharge the capacitor using an insulated screwdriver shorted across its terminals — never touch the capacitor or its terminals directly, and never work on a microwave's internals without performing this step first. If you are not fully comfortable and experienced with high-voltage discharge procedures, have a qualified appliance technician perform this repair instead.
⚠️ Test Other High-Voltage Components Before Assuming It's The Magnetron Wear work gloves. After confirming the capacitor is fully discharged, remove the outer cabinet to access the internal components. Before replacing the magnetron, it's worth testing the other high-voltage components — the transformer, diode, and capacitor — since a fault in any of these can produce similar "runs but doesn't heat" symptoms, and replacing the magnetron alone won't fix the problem if one of these other parts has actually failed. Photograph the magnetron's mounting and waveguide connection before removing anything. Disconnect the magnetron's electrical leads, remove the mounting screws securing it to the waveguide assembly, and carefully lift the old magnetron free. Install the new 6324W1A001L in the same orientation, aligning it correctly with the waveguide opening, and secure the mounting screws. Reconnect the electrical leads exactly as they were before removal. Reinstall the outer cabinet, restore power, and test with a cup of water to confirm normal heating without unusual sounds, sparking, or smoke. Tools needed: nut driver or socket set, Phillips screwdriver, insulated screwdriver for capacitor discharge, multimeter (for testing other components), work gloves.

My microwave runs but doesn't heat anything. Is this the right part?
It's the most common cause of exactly that symptom. When the turntable spins, the display works, and the timer counts down normally, but food comes out just as cold as it went in, the magnetron has very likely failed. Other high-voltage components (the transformer, diode, or capacitor) can sometimes cause the same symptom, so if you're comfortable testing with a multimeter, it's worth ruling those out first — but a failed magnetron is the single most frequent cause reported for this exact complaint.
Why does the same part fit so many different brands?
LG manufactures magnetrons and other core components that get used across microwaves sold under many different brand names, since several appliance companies share manufacturing platforms or source key parts from the same suppliers rather than building everything in-house. This is a normal and well-documented part of how microwave manufacturing works — it doesn't mean the part is generic or lower quality, just that LG's magnetron design is used broadly across the industry.
I see sparking behind the cover inside the microwave. Is that the magnetron?
It can be. Sparking or arcing behind the waveguide cover, especially with visible smoke or a burning smell, points to damage in the magnetron or the waveguide area. Inspect the magnetron for burn marks once you've safely discharged the capacitor and opened the cabinet — if you see charring or damage, replacement is the correct fix. Stop using the microwave immediately if you notice sparking, smoke, or burning smells.
Do I need any special skills to replace this part?
This is a moderate DIY repair, and the key skill required isn't mechanical — it's safely discharging the microwave's high-voltage capacitor before doing anything else. If you're not fully confident performing that step correctly, this is a good repair to leave to a qualified appliance technician, since the capacitor can hold a dangerous charge even with the unit unplugged.
Is this an OEM or aftermarket part?
This is a genuine OEM part, manufactured by LG to factory specifications — guaranteed fit, materials, and performance. It matches the original microwave frequency output, mounting configuration, and dimensions of the magnetron originally installed in your microwave.

XPARTCO 8573713 Gas Dryer Thermal Cut-Off Fuse Replaces WP8573713
The XPARTCO 8573713 is an aftermarket replacement thermal cut-off fuse for Whirlpool, Maytag, Kenmore, Crosley, Amana, and Inglis gas dryers. This fuse is mounted on top of the burner funnel, directly under the drum, and it's a one-time safety device: as long as the dryer stays within its normal operating temperature, it does nothing at all, but the instant temperatures near the burner climb high enough — almost always from restricted airflow — the fuse permanently opens the circuit and cuts power. That's why a blown fuse produces such a specific symptom: the dryer won't heat, even though the drum may still tumble and the rest of the dryer seems to run normally.
Because this fuse sits on the burner funnel underneath the drum rather than on the more accessible blower housing, replacing it is a more involved repair than a typical thermal fuse swap — the drum has to come out of the cabinet to reach it. Unlike a resettable thermostat, this fuse cannot be reset once it blows; it must be replaced. A blown thermal fuse is almost always a symptom rather than a random failure: restricted exhaust venting is the leading cause, since trapped heat near the burner is exactly what this fuse is designed to react to. It directly replaces WP8573713, AP6013467, and PS11746693.
Quick Answer
The XPARTCO 8573713 Gas Dryer Thermal Cut-Off Fuse fixes Whirlpool, Maytag, Kenmore, Crosley, Amana, and Inglis gas dryers that won't heat, even if the drum still tumbles normally. Mounted on the burner funnel under the drum. Replaces WP8573713, AP6013467, PS11746693. Always inspect and clean the dryer venting when replacing this fuse — a blown fuse is a symptom of restricted airflow, and installing a new fuse without fixing the vent will likely blow it again.

Installation Notes
⚠️ Gas Safety — Shut Off The Gas Supply Before Starting This fuse sits directly on the burner funnel, close to the gas burner assembly. Before beginning, close the gas shutoff valve behind the dryer in addition to unplugging the dryer or shutting off its circuit breaker. If at any point you smell gas, stop immediately, leave the area, and do not operate any switches — contact your gas utility or a qualified technician. Do not attempt this repair if you are not comfortable working safely around a gas appliance's burner assembly; a qualified technician can complete it instead.
⚠️ Drum Removal Required — Inspect And Clean The Venting Before Reassembling Wear work gloves. This repair requires removing the drum from the dryer cabinet to access the burner funnel, so budget more time and disassembly than a typical thermal fuse swap. Remove the top and front panels according to your model's service diagram, disconnect the drive belt from the idler pulley, and lift the drum out of the cabinet to expose the burner funnel underneath. Photograph the wiring before disconnecting the old fuse's connectors. Test the old fuse for continuity with a multimeter to confirm it's actually blown (no continuity) rather than assuming, and test the new fuse to confirm it's good out of the box. This is the most important step: fully inspect and clean the dryer's exhaust vent, from the lint trap housing all the way to the exterior vent hood, checking for lint buildup, crushed sections, or excessive length. A blown thermal fuse is a symptom of restricted airflow, and skipping this step means the new fuse is likely to blow again. Install the new 8573713 fuse on the burner funnel in the same mounting position, reconnect the wiring, and reassemble the drum, belt, and panels in reverse order. Restore the gas supply and power, and run a test cycle to confirm normal heating and shutoff behavior. Tools needed: Phillips or nut driver (model-dependent), multimeter, vent brush or vacuum attachment for cleaning ductwork, work gloves.
Frequently Asked Questions
My dryer tumbles fine but there's no heat. Is this the right part?
Yes, this is the classic symptom of a blown gas dryer thermal cut-off fuse. Because this fuse only interrupts the heating circuit and not the drive motor, the drum can continue tumbling completely normally while the dryer produces no heat at all. If you've confirmed the burner isn't igniting and the fuse tests as an open circuit, this is very likely the fix.
Why does this repair require removing the drum? My other dryer's fuse didn't need that.
This particular fuse is mounted on the burner funnel underneath the drum rather than on the blower housing at the back of the cabinet, which is where many thermal fuses on other platforms are located. Reaching the burner funnel requires taking the drum out of the cabinet, which is why this repair involves more disassembly than some other thermal fuse replacements.
I replaced the fuse and it blew again. What's going on?
This is a strong sign that the underlying cause — almost always restricted airflow — was never addressed. Thermal fuses don't fail from age; they blow because the dryer overheated. If a new fuse keeps blowing, thoroughly inspect and clean the entire exhaust path from the lint trap housing to the outside vent hood, checking for lint buildup, crushed or kinked ductwork, or a vent run that's too long.
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 to match the electrical specifications and mounting configuration of the original WP8573713 thermal cut-off fuse used in compatible Whirlpool, Maytag, Kenmore, Crosley, Amana, and Inglis gas dryers.

Warning:The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. If the magnetron burns out, the microwave won’t heat. The magnetron is not repairable—if the magnetron is burned out, you must replace it. (Warning: The microwave oven can store a lethal amount of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. Due to the high running voltage and the potential for electric shock, it is extremely dangerous to replace the electronic components in a microwave. Only a licensed technician should replace the magnetron.)
