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.)

4 Pack - XPARTCO EXP480 Microwave Door Switch (NC - NO) Normally Closed / Open
The XPARTCO EXP480 is a universal replacement 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 combines both a normally closed (NC) and normally open (NO) contact set in a single body, matching the dual-contact design used across a wide range of microwave door latch mechanisms.
Rated 16A maximum current, 250VAC maximum voltage, with an IP40 protection rating. Over time, these switch contacts can wear, pit, or fuse together from repeated cycling and the electrical load they carry 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 in less common but more serious cases, a switch that has fused shut and continues carrying current even when it shouldn't. It directly replaces 28QBP0496, W10211972, 4375346, W10330566, WPW10330566, 1472224, 4393442, 4393498, 4393570, 4393697, 4393881, 461967848881, 8206345, W10131248, W10217468, AH2338920, EA2338920, AP4357880, PS2338920, KW3A-16Z0-A200-76, W10727360, W10269457, 3379124, AP5950105, and PS10057151.

Compatibility
This door switch is a universal replacement compatible with convection microwave ovens, grill microwave ovens, microwave/oven combination units, and solo microwave ovens across many brands, wherever the original switch matches this NC/NO contact configuration and electrical rating.
Note: Microwave door interlock systems typically use two or three separate switches working together (primary interlock, monitor/secondary switch, and sometimes a third safety switch), and not all of them share this same NC/NO configuration. Confirm which specific switch position has failed on your microwave, and match the contact configuration and electrical rating exactly — never substitute a switch with a different configuration. Always verify your full model number before ordering. Contact our support team with your model number if you're unsure which switch your microwave needs.

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 EXP480 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.
My microwave trips the breaker whenever I open the door. What does that mean?
This can indicate that one of the door switches — often the one that should open when the door opens — 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.
My microwave uses more than one door switch. How do I know which one to replace?
Most microwaves use two or three separate interlock switches working together, and they don't always share the same contact configuration. Check your appliance's parts diagram or the physical switch you're replacing to confirm it matches this NC/NO combination design before ordering, and always test or verify function with a multimeter if you're uncertain which specific switch has failed.

XPARTCO W10721967 Washer Drive Clutch Kit
The XPARTCO W10721967 is an aftermarket replacement drive clutch kit — often called a "splutch" kit — for Whirlpool-built top-load washers. This assembly sits at the base of the transmission and works together with the mode shift actuator to control how power reaches the washer: during agitation, the clutch engages to drive the washplate back and forth, and during spin, it locks up to spin the inner wash basket at full speed. The name "splutch" comes from what it actually is — part spring, part clutch — and that spring-loaded design is what lets the same assembly smoothly transition between the gentle agitate motion and the much more forceful spin cycle.
This is a complete 6-piece kit: spring, clutch housing, cam ring, basket drive gear, drive pulley, and mounting nut, so you're replacing the entire wear-prone assembly at once rather than chasing individual worn components. Over time the clutch's friction surfaces glaze over and wear down, the cam ring's engagement points round off, and the spring loses tension — all of which produce the same telltale complaint: a loud grinding, clicking, or clunking noise during agitation or spin, sometimes alongside a washer that spins weakly, agitates but won't spin, or runs hot and starts to smell from the friction of a slipping clutch. It directly replaces AP5951296, W10006352, W10006353, W10006354, W10006356, W10006382, W10239973, W10315818, W10326374, W10536113, W10721967VP, W10818965, W11396423, 3319979, and PS10057144.

Installation Notes
⚠️ Unplug Washer And Shut Off Water Before Starting — Tip Onto Its Back Or Front With Care Disconnect power at the outlet or shut off the circuit breaker, and close the water supply valves before beginning. Wear work gloves. Access is from underneath the washer: remove the inner wash basket first (this typically requires a large basket-hub or spanner tool and applying steady upward pressure to break the basket free from the drive hub), then carefully tip the washer onto its back or front, protecting the top and any control panel with a blanket or padding as you lay it down. Photograph the belt and pulley arrangement before disconnecting anything. Remove the drive belt from the motor pulley, then remove the mounting nut and pull the old clutch/pulley assembly off the transmission shaft — a puller tool can help if it's seized. Install the new W10721967 assembly onto the shaft in the same orientation, torque the mounting nut to the manufacturer's specification, and reinstall the drive belt, checking that it seats correctly in the pulley grooves. Carefully stand the washer back upright, reinstall the wash basket, and reconnect it to the drive hub. Restore water and power, then run a full test cycle through agitate and spin, listening for the grinding or clicking noise that prompted the repair. Tools needed: basket-hub removal tool or spanner wrench, socket set, 13mm socket, 5/16" nut driver, pliers, work gloves, and a helper to assist with tipping the washer.
Frequently Asked Questions
What does "splutch" mean, and why is it sold as one kit instead of individual parts?
"Splutch" is shorthand for spring-clutch — the assembly combines a spring-loaded clutch mechanism with the drive pulley and gear that together control agitation and spin. Whirlpool sells this as a single kit because the individual components wear together and interact closely; replacing just the pulley while leaving a worn cam ring or a fatigued spring in place often means the noise or slipping symptom returns quickly. Replacing the complete kit resolves the failure at its actual source.
My washer agitates fine but won't spin. Is this the clutch?
It's one of the most common causes of exactly that symptom. The clutch has to lock up firmly to transfer full power into spinning the basket; if its friction surfaces have worn down or glazed over, it can still engage well enough for the lighter agitation motion but slip under the higher torque demand of spin. If you hear grinding or clicking specifically as the washer transitions into spin, that reinforces the clutch as the likely cause.
Should I replace the drive belt at the same time?
It's worth strongly considering. The belt and clutch wear on a similar schedule and share the same teardown — you're already tipping the washer over and removing the belt to access the clutch, so replacing a belt that's showing wear at the same time saves you from repeating the whole disassembly again in the near future. Inspect the belt for glazing, cracking, or fraying while it's off and replace it if it shows any of those signs.
The washer smells hot or burnt. Is that dangerous, and does it point to this part?
A worn clutch that's slipping generates friction heat, which can produce a warm, slightly burnt smell — this is a real symptom of clutch wear and not something to ignore, since continued operation in that state accelerates wear on the clutch and can stress the drive motor. If you notice this smell along with weak or absent spin, stop using the washer and address the clutch before running further loads.
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 spring tension, cam ring engagement geometry, pulley dimensions, and mounting configuration of the original W10721967 clutch kit used in compatible Whirlpool, Maytag, Kenmore, Amana, Crosley, Roper, and Inglis top-load washers.

XPARTCO EXP480 Microwave Door Switch (NC - NO) Normally Closed / Open
The XPARTCO EXP480 is a universal replacement 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 combines both a normally closed (NC) and normally open (NO) contact set in a single body, matching the dual-contact design used across a wide range of microwave door latch mechanisms.
Rated 16A maximum current, 250VAC maximum voltage, with an IP40 protection rating. Over time, these switch contacts can wear, pit, or fuse together from repeated cycling and the electrical load they carry 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 in less common but more serious cases, a switch that has fused shut and continues carrying current even when it shouldn't.

Compatibility
This door switch is a universal replacement compatible with convection microwave ovens, grill microwave ovens, microwave/oven combination units, and solo microwave ovens across many brands, wherever the original switch matches this NC/NO contact configuration and electrical rating.
Note: Microwave door interlock systems typically use two or three separate switches working together (primary interlock, monitor/secondary switch, and sometimes a third safety switch), and not all of them share this same NC/NO configuration. Confirm which specific switch position has failed on your microwave, and match the contact configuration and electrical rating exactly — never substitute a switch with a different configuration. Always verify your full model number before ordering. Contact our support team with your model number if you're unsure which switch your microwave needs.

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 EXP480 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.
My microwave trips the breaker whenever I open the door. What does that mean?
This can indicate that one of the door switches — often the one that should open when the door opens — 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.
My microwave uses more than one door switch. How do I know which one to replace?
Most microwaves use two or three separate interlock switches working together, and they don't always share the same contact configuration. Check your appliance's parts diagram or the physical switch you're replacing to confirm it matches this NC/NO combination design before ordering, and always test or verify function with a multimeter if you're uncertain which specific switch has failed.
