WG24 Microwave Universal Mica Sheet, Waveguide Cover (2.5" X 4.2")

Description

WG24 Microwave Universal Mica Sheet, Waveguide Cover (2.5" X 4.2")

The WG24 is a universal mica sheet for replacing the waveguide cover in a microwave oven. The waveguide cover sits over the opening where microwave energy enters the cooking cavity from the magnetron. It keeps food splatter, grease, and moisture out of the waveguide while letting microwave energy pass through. Over time the cover can become dirty, burnt, or damaged, and a damaged cover is a common cause of sparking or arcing inside the microwave.

This sheet measures 2.5" x 4.2". It is a universal, cut-to-fit part rather than a model-specific cover, so you trim it to match the shape and size of the original cover in your microwave.

Quick Answer

The WG24 Universal Mica Waveguide Cover Sheet (2.5" x 4.2") replaces a burnt, damaged, or missing waveguide cover in a microwave that sparks or arcs inside the cavity. Trim it to match your original cover. Classic symptom: sparks or burn marks near the waveguide opening on the inside wall of the microwave.

Common Problems This Part Fixes

  • Sparking or arcing inside the microwave cavity
  • Burn marks or damage at the waveguide cover
  • Missing, cracked, or warped waveguide cover
  • Grease or food buildup on the waveguide cover

If your microwave uses a molded cover with its own part number, contact our support team with your model number before ordering and we will help you choose between this sheet and the model-specific cover.

  • Covers you can trace and trim to match the original

Note: Measure your original cover before ordering. If it is larger than 2.5" x 4.2", or is a shaped cover with its own mounting tabs or pins, this sheet may not be the right size or style. Contact our support team with your model number and we will help confirm.

Installation Notes

⚠️ Danger: High-Voltage Capacitor Inside Unplug the microwave before beginning. A microwave contains a high-voltage capacitor that can hold a dangerous, even lethal, electrical charge after it is unplugged. If you are not trained to discharge it safely, do not open the outer cabinet. The waveguide cover is inside the cooking cavity, and on many models you must open the cabinet to reach it. Wear work gloves, and follow your model's service guide.

Remove the old cover and trace its shape onto the mica sheet, then cut the sheet to match with scissors or shears. Clean any grease or food residue from the waveguide opening before fitting the new cover. Secure it the same way the original was held in place, and run a short test with a cup of water to check for sparking.
