• Should the waveguide cover in MWD or MD be replaced if it is burnt, chipped or cracked?
• Is a service technician required to replace the waveguide cover in a microwave drawer?
• Can the MWD or MD be used without the waveguide cover?
• What is the purpose of the microwave waveguide cover?
• What is a stir cover?

Answer:

The waveguide cover, or stir cover, covers the aperture where microwaves enter the oven cavity from where they are produced by the magnetron. It also stops moisture and food particles getting into the 'workings' of the microwave.

• Replace the waveguide cover if it is burnt, chipped or cracked. Do not operate a microwave with a burnt, chipped or cracked waveguide cover or without the waveguide cover in place.
• Waveguide cover replacement in a MWD Microwave Drawer or MD Microwave Drawer is a difficult repair that requires service.
