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.

EXP499 Microwave Door Switch (Normally Closed)
The EXP499 is a universal replacement normally closed (NC) door interlock switch for microwave ovens and microwave/oven combination units. This is a critical safety component: microwave door interlock switches exist specifically to cut power to the magnetron the instant the door opens, preventing any possibility of microwave radiation escaping the cavity while the door isn't fully closed and latched. This switch's normally closed contact design matches a wide range of microwave door latch mechanisms across GE, Whirlpool, Samsung, LG, Kenmore, and other brands.
Rated 16A, 125/250VAC. Over time, this switch's contacts can wear, pit, or fuse together from repeated cycling and the electrical load carried every time the door opens and closes. A failing interlock switch typically shows up as a microwave that won't start at all, a display that works but the unit won't heat, or intermittent operation tied to the door latch area. This is the normally closed counterpart to our EXP497 (normally open) and EXP480 (combined NC/NO) listings — always confirm which specific contact configuration your microwave's failed switch uses before ordering.
Quick Answer
The EXP499 Microwave Door Switch (Normally Closed) fixes microwave ovens and microwave/oven combos that won't start, won't heat, or operate intermittently near the door latch area. 16A, 125/250VAC, normally closed (NC) contact design. Never operate a microwave with a bypassed, disconnected, or suspected-faulty door interlock switch — these switches exist to prevent radiation exposure and must always be replaced with a properly rated part, never removed or defeated.
Common Problems This Part Fixes
Microwave won't start at all, even though the display and buttons respond normally
Microwave display and timer work, but the unit won't heat
Microwave stops working intermittently, especially around the door latch
Clicking or buzzing sound from the door area without the microwave starting
Breaker tripping when the door is opened, indicating a switch contact that has fused shut
Door that doesn't feel like it's latching securely

Installation Notes
⚠️ Danger — Never Bypass A Door Interlock Switch Unplug the microwave before beginning any work, and if it's a built-in or over-the-range unit, shut off power at the breaker as well. Microwave ovens also contain a high-voltage capacitor that can retain a dangerous electrical charge even after the unit is unplugged — avoid touching internal components near the capacitor and magnetron. Door interlock switches are a critical safety system: they exist specifically to cut power the instant the door opens, preventing microwave radiation from escaping the cavity. Never operate a microwave with an interlock switch disconnected, bypassed, or jumpered, even temporarily — doing so can expose you and others to microwave radiation. If you are not fully comfortable working inside a microwave's internal compartment, have a qualified appliance technician perform this repair instead.
⚠️ Photograph Wiring Before Disconnecting — Match The Failed Switch Exactly Wear work gloves. Remove the outer cabinet or access panel per your model's service instructions to reach the door switch assembly, typically located near the door latch mechanism. Photograph the wiring on the old switch before disconnecting anything, and confirm you're replacing the correct switch position if your microwave uses multiple interlock switches. Disconnect the wire terminals from the old switch, remove its mounting screws, and pull it free. Install the new EXP499 in the same position, reconnect each wire terminal to its original position, and secure the mounting screws. Reinstall the cabinet or access panel. Restore power and test that the microwave starts normally with the door closed, and — this is the critical safety check — confirm the unit stops heating immediately when the door is opened during a test run with a cup of water. Tools needed: Phillips screwdriver, work gloves.
Frequently Asked Questions
My microwave stopped working. How do I know if it's actually a door switch and not something else?
A common pattern is a microwave where the display and buttons respond normally, but pressing start does nothing, or the unit hums without heating — this points toward the door interlock circuit rather than the control board. Since these switches also serve a critical safety function, if you suspect a fault in this area, it's best to have it properly diagnosed and replaced rather than working around the symptom.
Is it safe to just disconnect a faulty interlock switch so the microwave will run?
No — this is not safe under any circumstances. Door interlock switches exist specifically to cut power to the magnetron the instant the door opens, preventing microwave radiation from escaping. Bypassing, disconnecting, or jumpering one of these switches removes that protection and can expose you and anyone nearby to microwave radiation, even if the microwave otherwise appears to run normally. Always replace a faulty switch with a correctly rated new one rather than working around it.
How is this different from your EXP497 and EXP480 listings?
These are different contact configurations for different switch positions in a microwave's door interlock system. This EXP499 is normally closed (NC) only. Our EXP497 listing is normally open (NO) only, and our EXP480 listing combines both NC and NO contacts in a single switch body. Since most microwaves use two or three interlock switches with different configurations, check which contact type your specific failed switch uses before ordering.
My microwave trips the breaker whenever I open the door. What does that mean?
This can indicate that one of the door switches has fused or welded its contacts shut from repeated electrical stress, so it continues carrying current when it shouldn't. This is a genuine safety concern and the affected switch should be replaced promptly rather than continuing to use the microwave.

The float switch is the safety device that shuts off the water fill valve if the water level gets too high before the timed fill cycle ends, so a failed float can mean overfilling or a dishwasher that won't fill properly.
This is a direct-fit aftermarket replacement for the original Whirlpool float switch, which is sold as W10195039 and WPW10195039. Float problems can look like valve or control problems, so check the float for a stuck or damaged action before replacing it.
Quick Answer
The XPARTCO W10195039 Float Switch fixes a Whirlpool-built dishwasher that overfills, leaks from too much water, or won't fill because the float is stuck, damaged, or no longer switching. It is also listed as WPW10195039. Classic symptom: water keeps filling past the normal level, or the dishwasher won't fill and the float looks stuck or cracked.
Common Problems This Part Fixes
Dishwasher overfills or the water level gets too high
Water leaking from too much water in the tub
Dishwasher won't fill because the float switch is stuck or failed
Float is cracked, broken, or doesn't move freely

Install the new float switch in the same position, reconnect the wires, and check that the float moves freely before closing the dishwasher. Run a cycle and check for leaks.
Frequently Asked Questions
What does the float switch do?
It shuts off the water fill valve if the water level gets too high before the timed fill cycle ends. It is a safety device that helps prevent overflow.
My dishwasher still won't fill. Will this fix it?
Only if the float is the cause. A dishwasher that won't fill can also have a bad inlet valve, a clogged inlet screen, or a control problem. Check that the float moves freely and test the valve first.
Is W10195039 the same as WPW10195039?
Yes. W10195039 is the older Whirlpool number and WPW10195039 is its replacement. This float switch covers both.
Will this fit my dishwasher?
It is listed for many Whirlpool-built dishwashers, 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.

XPARTCO HS810 Refrigerator 3-in-1 Hard Start Kit 1/12 to 1/5 HP 120V
The XPARTCO XPHS810 is a universal 3-in-1 hard start kit that combines a solid-state starting relay, a start capacitor, and thermal overload protection into a single prewired unit for refrigerator and freezer compressors rated 1/12 to 1/5 HP at 120V (110–125VAC). It's designed as a direct equivalent to the widely used Supco RCO810 and similar kits, giving a struggling compressor extra starting torque to overcome internal friction and gas pressure at startup — commonly used to fix the classic "click-buzz-click" no-start symptom without replacing the entire compressor.
The kit is fully prewired with color-coded leads (typically black = Common, white = Start, red = Run) and mounts directly onto the compressor's terminal pins, with instructions printed on the unit itself. It directly replaces Supco RCO810, URCO810, URC0810, RC0810, RC100, TJ90RCO810, AP4503019, ERP810, ERPU810, HS8, HS810, HS81, PCS810, and Mars 32781. Installs in 15–30 minutes with basic hand tools.
Quick Answer
The XPARTCO HS810 3-in-1 Hard Start Kit fixes refrigerators and freezers whose compressor makes a repeated "click-buzz-click" sound and fails to start, or that shut off on thermal overload during startup. Combines relay, start capacitor, and overload protector in one prewired unit for 1/12 to 1/5 HP compressors, 120V, 3.5A RLA. Replaces Supco RCO810, URCO810, RC0810, RC100, TJ90RCO810, AP4503019, ERP810, HS8, HS810, HS81, PCS810, Mars 32781. Do not install on LG linear/inverter compressors — see Installation Notes.
Common Problems This Part Fixes
Compressor makes a repeated "click-buzz-click" noise and fails to start
Refrigerator or freezer runs warm because the compressor won't stay running
Compressor hums but doesn't start, then trips off on overload
Refrigerator cycles on and off rapidly without reaching temperature
Older or worn compressor that starts hard, especially after a power outage
⚠ Capacitor Hazard — Read Before Servicing This kit contains a start capacitor, which can store a dangerous electrical charge even after the refrigerator is unplugged. Always disconnect power before servicing, and discharge the capacitor safely (using an insulated-handle resistor tool or by briefly shorting the terminals with an insulated screwdriver) before handling it. Never touch capacitor terminals with bare hands. If you are not comfortable working around stored electrical charge, have this repair performed by a qualified technician.
Cross Reference Information

Installation Notes
⚠️ Unplug Refrigerator Before Starting — Discharge Capacitor Safely Disconnect power before beginning. Before touching any wiring, check your compressor's data label to confirm it is NOT a linear/inverter/BLDC compressor — this kit is not compatible with those and can damage the inverter board if connected. Access the compressor compartment, typically at the rear or bottom of the unit. Remove the existing relay/overload assembly by gently pulling it straight off the compressor terminal pins — do not force or twist. Use a multimeter to confirm which pins are Common (C), Start (S), and Run (R) if not already labeled. Connect the hard start kit's wires to the matching pins. Wire the kit's main power leads into the refrigerator's supply wiring using wire nuts, following the included diagram. Secure the kit with zip ties or its mounting strap to prevent vibration damage during compressor operation. Restore power and confirm the compressor starts smoothly without repeated clicking. Tools needed: nut driver or screwdriver, digital multimeter, wire nuts, insulated screwdriver (for capacitor discharge).
Frequently Asked Questions
My compressor makes a clicking or buzzing sound and won't start — will this fix it?
A hard start kit resolves this in many cases, especially on older or worn compressors that struggle to overcome internal gas pressure at startup. However, "click-buzz-click" can also indicate a failing compressor winding or a compressor nearing end of life. If the hard start kit doesn't resolve the issue, the compressor itself may need replacement — a hard start kit can extend a marginal compressor's life but can't revive one with failed internal windings.
Can I use this on any refrigerator?
This kit works on standard PSC and RSIR compressors within the 1/12 to 1/5 HP range at 120V. It is NOT compatible with LG linear/inverter compressors or any variable-speed inverter-driven compressor — connecting it to one of those can destroy the inverter control board. Check your compressor's label for "Inverter," "Linear," "BLDC," or "Digital" before ordering.
Do I need to remove my existing start capacitor or relay first?
Yes — remove the old relay/overload assembly from the compressor terminal pins before installing this kit. The XPHS810 is designed to work with or without an existing separate run capacitor remaining in the circuit, but the old start relay and any old start capacitor should be removed and replaced by this kit, not left in place alongside it.
Is this safe to install myself?
Many DIYers install hard start kits successfully, but this repair involves a capacitor that can hold a dangerous electrical charge even after the unit is unplugged, plus correctly identifying compressor terminals. If you're not comfortable working around stored electrical charge or don't have a multimeter to confirm terminal identification, we'd recommend having a qualified technician perform this repair.

XPARTCO 3405-001034 Microwave Door Switch (Normally Open)
The XPARTCO 3405-001034 is an aftermarket replacement normally open (NO) microwave door interlock switch for select Samsung, Whirlpool, Maytag, Kenmore and other microwave ovens, replacing part 3405-001034. The switch detects when the door is fully closed and completes the safety circuit, so the microwave runs only when the door is shut. When it fails, the microwave may not start, may not heat, or may only run if you push or jiggle the door.
Microwaves often use more than one door switch, and each is sold individually. Check that the switch you are replacing is the normally open type and goes in the same position.
⚠️ Critical Safety Part — Switch Type And Position Must Match Exactly Door interlock switches work together as a safety system. Installing the wrong type (normally open vs. normally closed) or putting a switch in the wrong position can let the microwave run with the door open, a serious radiation hazard. Replace each switch with the exact same type in the exact same position, and test the microwave after replacement. If you are not qualified to service microwave ovens, use a trained technician.
Quick Answer
The XPARTCO 3405-001034 Microwave Door Switch (Normally Open) replaces a failed normally open door interlock switch on a compatible microwave. Replaces 3405-001034 and 3405-000178. Classic symptoms: the microwave won't start, won't heat, or only runs when you push or jiggle the door.

Installation Notes
⚠️ Unplug Microwave And Beware Of The High Voltage Capacitor Unplug the microwave before starting and never operate it with the cabinet open. The high voltage capacitor can hold a lethal charge even after the microwave is unplugged. If your repair requires removing the outer cabinet, discharge the capacitor safely first, or have a qualified technician do the work.
⚠️ Photograph Switch Positions Before Removing Anything The switches are accessed at the door latch assembly. Before disconnecting anything, photograph each switch and its wiring, and move the wires one at a time so each goes back to the correct terminal. Make sure the actuator lines up with the latch and the switch clicks freely. After reassembly, test the microwave with a microwave-safe cup of water.
Frequently Asked Questions
My microwave won't heat or start. Is this the part I need?
A failed door switch is a common cause, but a microwave has several switches and other parts can cause the same symptoms. Identify which switch failed and confirm it is normally open before ordering.
Is this switch normally open or normally closed?
This is a normally open (NO) switch. It is not interchangeable with normally closed switches, which do a different job in the interlock system.
Is this an OEM or aftermarket part?
This is an aftermarket replacement from XPARTCO, made to replace part 3405-001034. If you specifically need a genuine part, contact our support team.
