Question about LG LMV1813ST Microwave Oven
The microwave timer works, but if I try to cook with it, it trips the household 15 amp circuit breaker. I plugged into another circuit to make sure it wasn't that breaker and it trips it as well just as soon as you press the start button.

The circuit breakers may both be functioning properly. What might be happening is that both circuits have other current drawing appliances on them. The circuit breakers react to the sum of all of the currents drawn by all of the devices on that circuit. So, if you have a 15 amp microwave and an 8 amp refrigerator on the same circuit, you would overload a 20 amp circuit by 3 amps.

The magnetron probably has a partial short pulling more current than normal as it runs, the other two items that give trouble is the high voltage diode, "sometimes cracks" to the high voltage capacitor, "usually shorts"

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)
