When I moved into my house, the microwave was not working, and GE "repaired" it. About 2 years later, it stopped working again [tripped the breaker and blew fuse]. I replaced the 20 amp fuse in it (probably the original "repair" as well), two times over a few months. Someone told me the circuit breaker would eventually fail and I should fix the problem, which I assumed was the microwave. The 3rd time it just tripped the breaker, then the 4th time days later the fuse and breaker both blew/tripped again. Bought a new microwave, but had the same problem on the FIRST day.
What could be causing the microwave's 20 amp fast-blow fuse to break repeatedly, and trip the breaker? I can't imagine I have two defective microwaves. Is there a short somewhere in the wiring to my outlet? If the voltage sagged somehow (bad breaker?), would the microwave try to compensate by drawing too much current?
The outlet measures 122V, with the "live" wire being on the right side. The microwave is on a dedicated outlet, which is the only place the problem has occurred, and pretty much the only place we've used the microwave.
Thanks for your suggestions.
