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.

Quick Answer
The XPARTCO EXP480 Microwave Door Switch (NC - NO) fixes microwave ovens and microwave/oven combos that won't start, won't heat, or have a door latch mechanism that isn't reliably cutting power when the door opens. 16A, 250VAC, combined NC/NO contact design. 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, PS10057151. 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.

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.
