NOTE: Before you begin any microwave repair, including this one, make absolute sure you unplug the microwave and discharge the capacitor first.

Replacing a microwave oven wave guide cover is a relatively simple task. That said, the process does vary from model to model. Here are the two most common ways to remove a microwave wave guide cover:

  1. Many wave guide covers are held in place with either a single screw or several screws. Remove the screw(s), and then slip the cover out of its housing.
  2. Other models require that you remove the entire outer cabinet of the microwave before you can remove the wave guide cover. In these models, the wave guide cover is most often secured to the internal right hand wall. With the outer cabinet removed, examine the right side of the unit. You should see where the wave guide cover secures in place. You will likely need to push down on the top of cover's clips to release it. Then reach inside the microwave and pull the cover out of the bottom slots.

Refer to your microwave owner's manual if neither of these processes apply to you.

CAUTION: Your microwave oven is capable of giving you a serious electrical shock, even when it is unplugged. We strongly suggest you seek the assistance of an appliance repair technician when conducting any microwave oven repair.
