Question about GE JVM1190 Microwave Oven
I have a Spacesaver that seems use 1.58 KW. Now and then it will trip the circuit breaker, which is a 15 Amp circuit. I suppose it is not rocket science to see that the 1.58 KW takes the whole 15 Amps and blows the breaker, but I am wondering if there is any way short of rewiring a 20 Amp circuit just for this microwave to cut down on the load this draws, and still have it work.
I do notice that the particular breaker switch is somewhat loose in its slot in the box. That may be a factor, but I don't know. The kitchen lights are on this line as well, so we try using the microwave with no lights on when it acts up, but it still will blow the breaker, once it starts doing it. It works for a bit, then blows it.
I don't think just reducing cooking power will help, as I think that just cycles the main tube on and off.
Any ideas here?
Since power = voltage X current, 1.58kW / 120VAC = 13.166A
So this unit should be fine on a 15A breaker unless the breaker is bad, the wiring or a connection is loose somewhere between the breaker and the microwave, or the microwave's magnetron or high voltage transformer are failing and drawing extra current.
Microwaves should really be on the own separate breaker if at all possible. Plus, the more a breaker trips, the more work out it gets.
Have you measured the voltage at the outlet? If that's off, current and power will be affected. It should be about 110-125VAC.
A good power test for outlet and wiring integrity is a toaster, toaster oven, or hair dryer rated at about 1500 watts.
If it doesn't run and heat steadily, then there may be a problem with the house wiring or breaker.
If it passes this test, the problem is likely in the microwave.
We're happy to help and we appreciate your thoughtful rating of our answer.

My GE spacemaker trips the breaker too. It has it's own breaker. After checking the outlet with a lamp, I changed the fuse but that is not the remedy. If the micro's door is closed I can flip the breaker on and it operates/cooks fine even withthe interior light on but has the word RESET on the readout just above the control touch pad. When on if I attempt to program a cook time, none of the key pad works but the word reset does disappear. Soon as I open the door after cooking, the breaker trips again when I opoen the door.
I will try the outlet suggestion with the toaster and see if the outlet can handel the watts/amps. If not the outlet wiring or outlet itself, I am open to other suggestions.
Please go easy on me....I am a single disabled mother who is playing Mrs. Fix It, but I am known as the Martha Stewart and Norm Abrum/Bob Villa of single moms. I have more power tools and knowledge than most men (thanks to my deceased father who was a contractor) but electrical is a bit more challenging for me expecially when attempting to diagnose.
