XPARTCO MWC21105 Microwave High Voltage Capacitor, 2100 VAC 1.05 µF
The XPARTCO MWC21105 is an aftermarket replacement high-voltage capacitor for microwave ovens. It stores and releases electrical energy in the high-voltage circuit that powers the magnetron, the part that actually generates the heat. When the capacitor weakens or fails, the microwave can stop heating while the display, turntable, and light still work normally. It can also hum, trip the breaker, or blow the fuse.
Rated 2100 VAC and 1.05 µF, this oval, bracket-mounted capacitor has 1/4" male terminals and fits a wide range of microwaves from GE, Whirlpool, Samsung, LG, Frigidaire, Panasonic, Sharp, Kenmore, and other brands. Because the same capacitor was used under many manufacturers' part numbers, it carries a long cross-reference list; see the Replaces list below. Each order includes 1 capacitor.

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.

Installation Notes
⚠️ Unplug Microwave Before Starting Disconnect power at the outlet. For over-the-range or built-in units, most turntable motors are accessed from inside the cavity by removing the drive coupler and roller guide, then reaching the motor from underneath the cavity floor (may require removing the microwave from its mount or accessing from the bottom/rear panel, depending on model). Photograph the wiring before disconnecting. Unplug the two spade terminal connectors from the old motor. Remove the mounting screws holding the motor bracket in place and remove the old motor. Install the new WB26X10038 motor in the same position and secure the mounting screws. Reconnect the spade terminals, matching your photos (polarity typically doesn't matter on these motors, but match original wire colors when in doubt). Reinstall the drive coupler and roller guide, reassemble any panels, restore power, and test that the turntable rotates smoothly and consistently. Tools needed: Phillips screwdriver, nut driver.
Frequently Asked Questions
My microwave heats food fine, but the turntable doesn't spin — is this the part?
Yes, this is the classic symptom of a failed turntable motor. The heating function (magnetron, high-voltage components) is a completely separate system from the turntable drive, so a microwave can heat normally while the turntable motor has failed. Before ordering, also check that the glass tray and roller guide are seated correctly, since a stuck tray can sometimes be mistaken for a motor failure.
Will this fit both GE and Frigidaire microwaves?
This motor design is shared across select GE-built and Frigidaire microwave models, but not every model on either platform uses it. Confirm fit using your microwave's exact model number before ordering rather than assuming by brand alone.
Do I need to transfer the drive coupler from my old motor?
The drive coupler (the plastic piece that connects the motor shaft to the turntable support) is typically a separate component that sits on top of the motor shaft rather than being permanently attached, so you'll generally reuse your existing coupler and roller guide with the new motor unless they're visibly worn or damaged.
Why is my turntable turning slowly or grinding instead of stopping completely?
This usually means the motor's internal gears are stripped or worn rather than the motor being fully dead — it's still trying to turn but can't do so smoothly. This is a sign the motor needs replacement even if it hasn't failed outright yet.

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.
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.

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 EXP20AG Glass Line Fuse, Fast Blow, 20A
The XPARTCO EXP20AG is an aftermarket replacement fast-blow glass line fuse rated 20A at 250V, used as the primary overcurrent protection component in microwaves and a range of other household appliances. A line fuse sits directly in the incoming power path: as long as current draw stays within its rating, it does nothing at all, but the instant a short circuit or an overcurrent condition pushes current past 20A, the thin wire element inside the fuse melts and opens the circuit — sacrificing itself to protect the more expensive components downstream, like a transformer, magnetron, or control board. A blown fuse is why an appliance can go from working normally to completely dead with no lights, no display, and no response to any button.
This is a standard-dimension glass cartridge fuse measuring 6mm x 30mm, fast-blow (fast-acting) rated, so it opens quickly once its rating is exceeded rather than tolerating a brief surge the way a slow-blow fuse would. It is commonly used across GE, Frigidaire, Whirlpool, Kenmore, and other brands' microwaves, and also turns up in HVAC control boards and various small appliances that use this same standard fuse size and rating. A fuse itself does not wear out from age the way a mechanical part does — if one has blown, it is a symptom of an overcurrent event somewhere else in the appliance, and it's worth understanding why before simply swapping in a new one.
Quick Answer
The XPARTCO EXP20AG Glass Line Fuse fixes microwaves and other appliances that have gone completely dead — no lights, no display, no response to any button. Fast-blow, 20A, 250V, standard glass cartridge, 6mm x 30mm. Commonly used across GE, Frigidaire, Whirlpool, and Kenmore microwaves and other appliances requiring this fuse size and rating. If a new fuse blows again right away, don't just keep replacing it — that almost always means there's an underlying short circuit that needs to be diagnosed first.
Common Problems This Part Fixes
Microwave completely dead — no display, no lights, no response to any button
Appliance suddenly stopped working with no warning
Microwave won't start even though the outlet has power
HVAC control board or other appliance electronics unresponsive
Appliance tripped off after a power surge or brownout
Visible blown or darkened fuse when inspected against a light
Continuity test shows an open circuit across the old fuse

Because this is a standard fuse size and rating rather than a brand-specific component, the exact OEM part number your appliance's manual references will vary. If your part number is not listed above, contact our support team before ordering and we will verify compatibility.
Compatibility
This fuse is compatible with select appliances from the following brands that use a standard 20A, 250V, fast-blow 6mm x 30mm glass cartridge fuse:
GE and Hotpoint microwaves (select models)
Frigidaire microwaves (select models)
Whirlpool and Kenmore microwaves (select models)
KitchenAid, Maytag, and Amana microwaves (select models)
Select HVAC control boards and other electronics using this fuse size and rating
Note — glass vs. ceramic body: This is the glass-body EXP20AG fuse. A visually similar ceramic-body fuse (commonly labeled EXP20A) is also widely sold at the same 20A/250V rating for many of the same appliances. Check which body material your appliance's original fuse used before ordering, and always match the amperage and voltage rating exactly — never substitute a higher-amperage fuse "to stop it from blowing," since that removes the very protection the fuse is designed to provide. Contact our support team with your model number if you're unsure which fuse your appliance needs.

Installation Notes
⚠️ Danger — Microwave High-Voltage Capacitor If you are replacing this fuse in a microwave, be aware that microwaves contain a high-voltage capacitor that can store a dangerous electrical charge even after the unit has been unplugged. Never open a microwave's cabinet without first discharging the capacitor using an insulated screwdriver shorted across its terminals, and never touch the capacitor or its terminals directly. If you are not fully comfortable with this step, have a qualified appliance technician perform the fuse replacement instead.
⚠️ Unplug The Appliance Before Starting — Match Amperage And Voltage Exactly Disconnect power at the outlet or shut off the circuit breaker before beginning. Locate the fuse holder — on most microwaves this is accessible after removing the outer cabinet, often near the incoming power cord or the control board. Remove the old fuse from its clip or holder and inspect it: a blown fast-blow fuse often shows a visibly darkened or broken filament, or a scorched glass body. Test with a multimeter set to continuity if the fuse looks intact but you suspect it's still bad — a good fuse shows continuity end to end, a blown one shows none. Install the new EXP20AG fuse in the same holder, making sure the amperage and voltage rating match your appliance's original fuse exactly. Reassemble the cabinet, restore power, and test the appliance. Tools needed: Phillips screwdriver, insulated screwdriver (for microwave capacitor discharge), multimeter (recommended), work gloves.
Frequently Asked Questions
I replaced the fuse and it blew again right away. What's going on?
A fuse doesn't fail on its own from age — it blows because something downstream drew more current than it should have. If the new fuse blows again immediately, that's a strong sign of an underlying short circuit or a failing component such as the transformer, magnetron, or a shorted capacitor. Continuing to replace the fuse without finding that root cause will just keep blowing new fuses, and in a microwave specifically, that diagnosis involves working near a high-voltage capacitor that should only be handled by someone comfortable discharging it safely, or by a qualified technician.
Can I use a higher-amperage fuse if this one keeps blowing?
No — this is one of the most important things to avoid with any fuse. The fuse's rating is chosen specifically to protect the wiring and components in the circuit it sits in. Installing a higher-amperage fuse "so it stops blowing" removes that protection and can allow a fault to overheat wiring or damage expensive components (or start a fire) instead of safely interrupting the circuit. Always replace a fuse with the same amperage and voltage rating as the original.
How do I know if the fuse is actually blown?
Visually, a blown fast-blow fuse often shows a broken or darkened filament inside the glass body, or scorching on the glass itself. If it looks fine but you still suspect it, the reliable way to check is with a multimeter set to continuity (with the appliance unplugged and the fuse removed from the circuit) — a good fuse reads continuity end to end, while a blown fuse reads open with no continuity at all.
Is EXP20AG the same as EXP20A?
They share the same 20A/250V rating, but EXP20AG refers to the glass-body version of this fuse while EXP20A commonly refers to a ceramic-body version sold for many of the same appliances. Check which body material your appliance's original fuse used, and if you're not sure, contact our support team with your model number for confirmation.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine brand-specific OEM part, but is manufactured to the same standard 20A, 250V, fast-blow glass cartridge dimensions and rating used across the OEM fuses in compatible GE, Frigidaire, Whirlpool, Kenmore, KitchenAid, Maytag, and Amana appliances.
