Appliance Repair Questions? Ask a Technician for Answers ASAP
Is the microwave completely dead ? no lights or anything at all ? if so the internal fuse has blown, this is inside the microwave. its an in line fuse, you can pick one of these up at lowes. be careful when you open the cabinet on this, microwave capacitors can store a powerful amount of voltage in them even when they are unplugged, its part # XXXXX on this diagram.
