XPG499 Microwave Door Switch (Normally Closed)
The XPG499 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 XPG499 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.

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 including GE, Whirlpool, Samsung, LG, and Kenmore, wherever the original switch matches this normally closed (NC) 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 normally closed (NC) configuration. This is a different part from our EXP497 (normally open) and EXP480 (combined NC/NO) listings. 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 XPG499 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 XPG499 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.

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 XPG499 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.

XPARTCO MCK69074904 Microwave Waveguide Cover / Insulator
The XPARTCO MCK69074904 is an aftermarket replacement waveguide cover, also known as an insulator cover or mica plate, for LG microwaves and select Bosch models. This cover protects the opening where microwave energy enters the cooking cavity from the magnetron. By covering that opening, it ensures microwaves are distributed evenly throughout the cavity while also preventing food particles, grease, and moisture from reaching and damaging the internal waveguide components.
Made of mica, a material that's essentially invisible to microwave energy, this cover measures approximately 4.88" x 4.94" (126mm x 124mm including tabs) and includes a locking button/pin tab for secure mounting. Over time, splattering food and moisture exposure can cause the mica to degrade, warp, or become contaminated, and old, damp, or contaminated mica can react to microwave energy by arcing. If this cover becomes damaged, you'll typically notice sparks or arcing inside the microwave during use, along with possible uneven heating as microwave distribution is no longer properly controlled. It directly replaces MCK69074904, MCK69074902, 4957254, AP6888006, EAP12725272, ALG55468, PD00056750, PS12725272.
Quick Answer
The XPARTCO MCK69074904 Microwave Waveguide Cover / Insulator fixes LG (and select Bosch) microwaves showing sparks or arcing inside the cavity during use, or heating unevenly. Mica plate, approx. 4.88" x 4.94", locking button/pin tab. Replaces MCK69074904, MCK69074902, 4957254, AP6888006, EAP12725272, ALG55468, PD00056750, PS12725272. Accessing this cover means opening the microwave's outer cabinet, which also exposes the high-voltage capacitor — treat that area with the same caution as any internal microwave repair.

Installation Notes
⚠️ Unplug Microwave Before Starting — Be Aware Of The High-Voltage Capacitor Inside Unplug the microwave from the wall outlet and move it away from the wall to give yourself room to work. Wear work gloves. Carefully remove the microwave's exterior cover, taking care not to tear or damage the clips that secure it in place, and set it aside. Microwave ovens 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 while working inside the cabinet. Locate the old waveguide cover inside the cavity, typically secured by a locking tab or small screws depending on your model. Remove the old cover, taking care not to damage the surrounding cavity surface. Install the new MCK69074904 in the same position, making sure it seats flush and the locking tab engages securely. Reinstall the exterior cover, restore power, and run a quick test with a cup of water to confirm normal heating with no sparking or arcing. Tools needed: Phillips screwdriver (model-dependent), work gloves.
Frequently Asked Questions
I see sparks inside my microwave. Is this the part I need?
Yes, this is the classic and most direct symptom of a damaged waveguide cover. Old, damp, warped, or food-contaminated mica can react to microwave energy by arcing at the point where it's damaged. Replacing the cover typically resolves this sparking immediately.
Is it safe to keep using my microwave if I notice sparking?
No, it's best to stop using the microwave once you notice sparking or arcing and replace the cover as soon as possible. Continued arcing can cause more serious damage to the magnetron and other internal components, turning a simple, inexpensive repair into a much costlier one.
What is mica, and why is it used for this part?
Mica is a naturally heat-resistant, corrosion-resistant material that is essentially invisible to microwave energy, meaning it doesn't interfere with or absorb the microwaves passing through it. This makes it ideal for a cover positioned directly in the path of the microwave energy entering the cavity, since it protects the opening without disrupting how the microwave actually cooks food.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine LG OEM part, but is manufactured to match the mica composition, dimensions, and mounting configuration of the original MCK69074904 waveguide cover used in compatible LG and Bosch microwaves.

Installation Notes
⚠️ Unplug Microwave Before Starting Unplug the microwave before beginning this repair. Wear work gloves to protect your hands. Locate the mounting screws or tabs securing the old vent grille in place, typically along the top or front edge of the unit depending on your model. Support the grille as you remove the mounting hardware, since a partially broken grille can shift or fall once released. Remove the old grille fully. Position the new W10245218 in the same location, aligning it with the mounting points, and secure it with the original screws or clips, taking care not to overtighten and crack the new plastic mounting tabs. Restore power and confirm the grille sits flush and securely in place with no gaps affecting the ventilation airflow. Tools needed: Phillips screwdriver, work gloves.
Frequently Asked Questions
My vent grille is cracked and hanging loose. What caused this?
This is a common failure mode, often caused by someone accidentally pulling, leaning on, or bumping the grille — enough force can crack the plastic screw mounting tabs, leaving the grille hanging or detached even though the rest of the microwave is unaffected. One customer described exactly this scenario: a guest accidentally pulled on the top grille vent, cracking the plastic screw tap and leaving it hanging.
How do I know I'm ordering the right color and part number?
Whirlpool sells several vent grilles that look very similar across different models, in both black and white finishes. This W10245218 is specifically the black-finish version. Compare your old grille's color and check your full model number against the compatibility list, or check the part number printed on your old grille if it's visible, before ordering.
Do I need any special tools to replace this grille?
No, this is a straightforward repair with basic hand tools — typically just a Phillips screwdriver to remove and reinstall the mounting screws or clips holding the grille in place.
Is this an OEM or aftermarket part?
This is a genuine OEM part, manufactured by Whirlpool to factory specifications — guaranteed fit, materials, and performance. It matches the original black finish and mounting configuration of the vent grille originally installed on your microwave.
