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.

Ed for Model Number 72166463500

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).
