Product Description

COVER,INSULATOR Specifications

This mica plate, also known as an insulator cover or a waveguide cover, protects the opening where microwaves enter the cooking cavity from the magnetron. By covering it, the plate ensures the even distribution of microwaves while also preventing food particles and vapor from causing damage to the internal components. If this cover becomes damaged, you may notice sparks or arcing inside the microwave during use. This replacement part is sourced directly from its original manufacturer.

Sparks from an old wave guide that needed to be replaced
Put microwave on its side as my hands weren’t ready enough to hold it up while trying to push it in.
Put board on the door to hold it open.
Gently pushed the wave guide back as far as it would go. Then, I carefully pushed the front tabs in place. No bending. I had practiced on the old one first. Broke the 2 old tabs by pushing back to hard so you need to be careful.
