Question about Sharp R-1480 Microwave Oven
My microwave oven, from time to time, blows the circuit breaker assigned to it. It does not share the circuit with anything else, so I've ruled out any external source for the overload. The oven works fine, as far as I can tell. But this intermittent problem suggest there might be something wrong with it.
Do you have any suggestions?
Have you ever replaced the fuse with Higher Amps fuse. There is a circuit diagram inside the cover please refer to that and ensure that the rating is same.

Either you have defected (weak) circuit breaker and wiring or bad Microwave oven.
The 99.99 % house hold Microwave ovens pull less than 15 Amps. They may have internal ceramic 15A fuse or 15 Amp internal circuit breaker.
To isolate your problem:
Plug your Microwave oven to different areas (different electrical circuit) if the different circuit breaker still trips... your Microwave oven has a short - Most of them has a small ceramic fuse 15 amps fuse.-also check some inter lock switches at door .
If the Microwave oven works Ok then you may have:
2a. You may overload the existing electrical circuit, try to unplug some other appliances
2b. You may have bad electrical outlet receptacle (Replace it with the same type , - may need helps from licensed electrician)
2c. Weak or defect house hold circuit breaker. (Replace it with the same type , brand - may need helps from licensed electrician)
