XPARTCO W10915651 Microwave Waveguide Cover
XPARTCO W10915651 Microwave Waveguide Cover
The XPARTCO W10915651 is an aftermarket replacement microwave waveguide cover compatible with select Whirlpool, KitchenAid, Jenn-Air, Maytag, Amana, Kenmore, Roper, Admiral, Magic Chef, Norge, Estate, and Ikea over-the-range and built-in microwave/oven combo models. The waveguide cover is a flat mica plate mounted on the interior right wall of the microwave cavity. It protects the waveguide — the channel through which microwave energy is directed into the cooking cavity — from food splatter, grease, and moisture. Without the cover, food particles can reach the waveguide and cause arcing, sparking, burning, and permanent damage to the magnetron or waveguide assembly.
Made from mica (a heat-resistant mineral material), this cover measures approximately 5-3/8" L x 1-3/4" W and clips or slides into the mounting slot on the interior wall of the microwave. It directly replaces W10687366, W10120230, WPW10120230, and 461967451001. Replacing a damaged or burned waveguide cover promptly is the single most important step in preventing more expensive microwave damage. Installs in under 5 minutes with no tools.

Installation Notes
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.
