2 PCS Microwave Oven Parts Mica Slice Super Thick Heat Insulation Accessories,Microwave Waveguide Cover/Mica for Sharp PCOVPB085MRP0

The waveguide covers the hole through which the microwaves are fed into the oven cavity from the waveguide
It acts as a barrier to stop grease and food particles from entering the opening of the waveguide
If the part begins to arc or spark during a cook cycle, it needs to be replaced. Continued use will cause burning of the paint and cavity and will eventually damage the magnetron tube
