Installation Notes
⚠️ Danger: Lethal Charge — Qualified Technician Installation Only A microwave high-voltage capacitor can hold a lethal electrical charge even after the microwave is unplugged. Installation should be done by a qualified service technician who knows how to safely discharge and test the high-voltage circuit. Do not touch the capacitor or its terminals, and do not open the microwave cabinet, unless you are trained to do so. Unplugging the microwave does not make this circuit safe. A technician will normally unplug the unit, safely discharge the capacitor, and note the wiring before removal. Match the replacement's capacitance, voltage rating, and terminal layout to the original, mount it securely in the same bracket position, reconnect the wiring as it was, and confirm all covers are back in place before powering the microwave.
Frequently Asked Questions
My microwave runs but doesn't heat — is the capacitor the problem?
A failed high-voltage capacitor is one common cause of a microwave that runs but doesn't heat. Other high-voltage parts, such as the diode and the magnetron, can cause the same symptom, so a technician will usually test them together before replacing parts.
Is it safe to replace this myself?
We recommend a qualified service technician install this part. A microwave capacitor can retain a lethal electrical charge even when the microwave is unplugged, and the high-voltage circuit is dangerous to work around without the right training and tools.
Can I use a capacitor with a different capacitance or voltage?
No. Use the same rating as your original. This listing is a 1.05 µF, 2100 VAC capacitor. A 1.0 µF capacitor (13QBP21100) is a different part and is not a substitute.
What's included in the order?
1 high-voltage capacitor. It does not include a diode, fuse, or other components.

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.

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 WB24X10146 Microwave Door Switch
The XPARTCO WB24X10146 is an aftermarket replacement micro switch (also called a door interlock switch) compatible with a wide range of GE, Hotpoint, RCA, Kenmore, and Sears over-the-range and countertop microwaves. This is a "stand on" style normally-open (NO) interlock switch, identified by the internal designation KW3A-NO, that mounts near the door latch and only closes its circuit when the door is fully shut and latched. The control board reads this switch as part of a multi-switch safety interlock chain that confirms the door is secure before allowing the magnetron to energize.
When this switch fails, the microwave commonly won't start at all, trips a door-related error code, or in rare cases can allow the unit to run with the door not fully secured — which is a safety-relevant fault, not just a convenience one. It directly replaces WB24X10146, WB24X28941, MW-7100-33, AGE22794, AH1019163, AP3866977, 1166990, EA1019163, EAP1019163, PD00039881, PS1019163. Installs in 15–20 minutes with basic hand tools.
Quick Answer
The XPARTCO WB24X10146 Microwave Door Switch fixes GE, Hotpoint, RCA, and Kenmore/Sears microwaves that won't start, display a door-related error code, or have a door that doesn't reliably confirm as closed. Normally-open (NO) "stand on" interlock switch, rated 250VAC / 16A, with 0.187" (4.7mm) quick-connect terminals. Replaces WB24X10146, WB24X28941, MW-7100-33, AGE22794, AH1019163, AP3866977, 1166990, EA1019163, EAP1019163, PD00039881, PS1019163. Classic symptom: turntable light and display work, but pressing Start does nothing.
Common Problems This Part Fixes
Microwave won't start when Start is pressed, even though the display and light work
Door-related error code or fault light on the display
Microwave randomly shuts off mid-cycle
Door feels like it isn't latching or registering as closed
Clicking sound from the door area with no response from the microwave
Intermittent operation that seems tied to how hard the door is closed
⚠ Safety-Relevant Component Door interlock switches are safety components that prevent the magnetron from energizing unless the door is fully closed and latched. Never bypass, jumper, or defeat a microwave door switch to "get it working" — doing so can allow microwave energy to leak while the door is open, which is a genuine radiation safety hazard. Always disconnect power before servicing, and replace all interlock switches in the chain if more than one shows signs of wear.

Installation Notes
⚠️ Unplug Microwave Before Starting Disconnect power at the outlet, and for built-in/over-the-range units also switch off the dedicated circuit breaker — microwaves store high voltage in the capacitor even after unplugging. Remove the outer cabinet or control panel cover to access the door switch assembly near the latch mechanism. Photograph the wiring before disconnecting, since GE microwaves typically use two or three interlock switches wired in sequence and mixing up the connections can leave the unit unsafe to operate. Disconnect the quick-connect terminals from the old switch, noting which wire goes to which terminal. Remove the mounting screw(s) holding the switch to its bracket and remove the old switch. Install the new WB24X10146 in the same position and secure it with the mounting screw(s). Reconnect the terminals exactly as photographed. Reassemble the cabinet or panel, restore power, and test that the door registers correctly and the microwave starts normally. Tools needed: Phillips screwdriver, nut driver (for cabinet screws).
Frequently Asked Questions
My microwave's display and turntable light work, but it won't start — is this the part?
This is a classic symptom of a failed door interlock switch. The control board needs a confirmed "door closed and latched" signal from all switches in the interlock chain before it will energize the magnetron. If that signal is missing from even one switch, most GE microwaves will power up normally but refuse to start a cook cycle. Confirm with a multimeter continuity test on the suspect switch before ordering, since GE microwaves usually use more than one interlock switch.
Is this the same as the EXP499 or EXP497 microwave door switch?
No — while all three use similar 4.7mm terminals, they are different switches used in different microwave platforms and are not interchangeable. WB24X10146 is GE's own "stand on" KW3A-NO design. Always match by part number rather than terminal size or general appearance.
Is it safe to keep using the microwave if I suspect this switch is bad?
We'd recommend not continuing to use it until it's repaired. Door interlock switches exist specifically to prevent microwave energy from leaking out while the door is open or not fully latched. If a switch is failing intermittently, the microwave may seem to work sometimes, but that's not a reason to keep using it — replace the switch before further use, and never attempt to bypass or jumper an interlock switch.
How many interlock switches does my GE microwave have, and do I need to replace them all?
Most GE microwaves use two or three interlock switches wired in sequence (often a primary switch, a secondary/monitor switch, and sometimes a door sensing switch). You typically only need to replace the specific switch that's testing bad, but if one has failed from age or wear, the others are often not far behind — some technicians replace the full set at once to avoid a repeat repair call.
