Once the fuse is replaced, the microwave oven works fine for a while and then the fuse blows again. If I replace it again, it works fine again for a short period and blows the fuse again.
Answer Hello Ed,
This is normally caused by a bad door switch. If one door switch is bad, the others will fail soon so it is normally recommended to replace all three at the same time. This unit uses two (AP4437957) and one (AP4629337).
The microwave turns on when I shut the door, no heat, timer does not run....What part would I need to replace?
Answer Hello Julie. Based on the information you provided, one of the door switches is bad and will need to be replaced.
