Installation Notes
⚠️ Unplug Microwave Before Starting Unplug the microwave before beginning. Open the microwave door and locate the waveguide cover on the interior right wall of the cavity — it is a flat rectangular plate, typically tan or off-white in color. If the old cover is burned, it may be stuck to the wall or disintegrating — carefully remove any remaining pieces and wipe the mounting area clean. Slide or clip the new W10915651 cover into the mounting slot on the right wall of the cavity — it should seat flat against the wall with no gaps. Ensure the cover is fully seated before use. Do not operate the microwave with a missing, cracked, or burned waveguide cover — even a small burn hole can cause arcing and progressive damage. Restore power and run a brief test cycle to confirm normal operation. Tools needed: None. A damp cloth may be needed to clean the mounting area.
Frequently Asked Questions
What does the waveguide cover do and why does it need to be replaced?
The waveguide cover is a thin mica plate that covers the opening of the waveguide — the channel through which microwave energy travels from the magnetron into the cooking cavity. Its job is to prevent food particles, grease, and steam from entering and contaminating the waveguide. When food splatter builds up on the cover and burns, the cover develops scorch marks or burn-through holes. These damaged spots absorb microwave energy and cause arcing — sparks and electrical discharges that can quickly damage the magnetron, which is the most expensive component in the microwave. Replacing the waveguide cover promptly when it shows damage is the least expensive and most important preventive maintenance you can do for a microwave.
Can I use the microwave without the waveguide cover?
No — never operate a microwave with a missing, cracked, or burned waveguide cover. Without the cover, food particles and moisture can enter the waveguide directly, causing immediate arcing and sparking. Even a small hole in the cover can cause arcing. Operating the microwave in this condition risks damaging the magnetron (a $100–$200 or more repair), burning the waveguide channel, or creating a fire hazard. The waveguide cover is inexpensive and installs in minutes — always replace it before using the microwave again.
My microwave is sparking — will replacing the waveguide cover fix it?
Sparking is almost always caused by a burned or damaged waveguide cover, and replacing the cover resolves the sparking in the vast majority of cases. However, if the waveguide itself (the metal channel behind the cover) has been damaged from prolonged arcing, or if metal debris from a burned cover has entered the waveguide, additional cleaning or component repair may be needed. Inspect the area behind the old cover after removing it — if the wall or channel shows deep burn damage, contact our support team or a technician before operating the microwave again.
How do I prevent the waveguide cover from burning again?
The most effective prevention is to keep the interior of the microwave clean — specifically the waveguide cover itself and the walls near it. Wipe down the cover and interior walls with a damp cloth after each use, especially after heating anything that splashes or spatters. Use a microwave-safe cover or lid over food when heating. Never operate the microwave when empty, as this directs all microwave energy at the waveguide cover without any food to absorb it. With regular cleaning, a mica waveguide cover can last for years without needing replacement.
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 from heat-resistant mica to match the dimensions and fit of the original W10915651 waveguide cover.

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.
