Question about Microwave Ovens
That model has a stirrer motor and blade in the ceiling above the waveguide cover.
Arcing can occur if there is grease or food particles on the front or back of the stirrer cover, on the blade or around the motor shaft.
You would need to remove the stirrer cover and inspect the parts, then use a damp cloth to wipe the parts clean.
We have a partial service manual for this model and have uploaded it to our site here to help you. You may also need to refer to this base manual.
