I have a 5-year-old kenmore over the range microwave oven. The fuse was
blown the other day and the oven was completely dead. So I replaced the
fuse, plugged it back in, display lighted up, opened the door, put a cup of
water in, closed the door, set 1 min., and almost as soon as I pressed START
, the fuse blown.
So I replaced the fuse again and went through almost the same steps as above
except that I did not open and close the door this time since the water was
already inside, pressed START, everything went well, the water came out hot
as it should.
What caused the fuse to blow? door switch or high voltage capacitor?
