140162957017 Genuine Mica Cover for Electrolux Group Microwave Ovens, Waveguide Cover Replacement Part

Part 140162957017 is a genuine Electrolux group mica cover. In a microwave oven, the mica cover is the thin panel inside the cavity that shields the waveguide opening, where microwave energy enters the cooking space. The stock description doesn't give the cover's size or the appliance model, so check the number on your old cover or the parts list for your oven before ordering.

Microwave sparking inside? Check the mica cover

Mica lets microwave energy pass through while keeping food splatter and steam out of the waveguide. Over time, grease and food soak into the mica and carbonise. Once that happens, the cover can spark, arc, burn through or leave black marks, often with a crackling noise and a burning smell while the oven is running. Ignoring it can damage the waveguide and, eventually, the magnetron. A cover that's only lightly marked can sometimes be cleaned, but a burnt, swollen or holed cover should be replaced.

Changing the mica cover

Unplug the microwave first. Never remove the outer cabinet, as the high voltage parts inside can hold a dangerous charge even when unplugged. The mica cover sits inside the cooking cavity and is usually held by clips or a small screw. Clean any carbon off the cavity wall, fit the new cover the same way round and test the oven with a cup of water.

Can I cut my own cover from a mica sheet?
