00608003 OEM Mica Sheet 30cm x 30cm, Cut to Size Microwave Waveguide Cover, Universal Microwave Part

Burnt or split waveguide cover in your microwave? This 30cm x 30cm mica sheet, part 00608003, lets you cut a new one to the exact shape you need. It's an OEM replacement sheet that isn't tied to any one brand, so it suits most microwaves that use a flat mica cover inside the cavity. One sheet is usually enough for more than one cover, depending on the size of your original.

Microwave sparking and a burnt waveguide cover

Most microwaves have a small flat panel on the cavity wall, called the waveguide cover. It lets the microwave energy through while stopping food splatter and grease from getting into the waveguide behind it. Over time that panel soaks up fat and moisture. Once it carbonises you'll see dark scorch marks, smell burning, or notice sparks and crackling while the microwave runs. A cover in that state needs replacing, because the burnt patch keeps arcing and can damage the cavity paint and the parts behind it.

• Cut to size to make a replacement waveguide cover

Making and fitting a new cover

Unplug the microwave before you start. Ease the old cover off its clips or screws, lay it on the sheet and trace around it, including any holes and tabs. Cut slowly with sharp scissors or a craft knife. Clean every trace of carbon off the cavity wall first, as leftover burnt spots can keep sparking. Never remove the outer casing, because microwaves hold high voltage inside even when unplugged.

Questions about this part

How do I cut the mica sheet without it splitting?

Use your old cover as the template and cut slowly with sharp scissors or a craft knife. Mica is built up from thin layers, so avoid bending the sheet hard or tearing at the corners, which can make the layers peel apart.
