I have a GE Profile PVM9005SJSS microwave oven. It worked fine for 2 years but now it is tripping the circuit breaker whenever I turn it on. I have tried plugging it into different outlets with same result so I think the microwave has a short circuit in it somewhere. Wondering if anyone can help/guide how to fix it?

    Go to store or thrift store or craigslist, buy a new (or working used) one. Dispose of the broken one. A working used one is almost always cheaper than attempting to repair. – Ecnerwal Feb 7 at 21:41

    Agreed with @Ecnerwal in this case. Things like dryers and dishwashers can be worth repairing, but microwaves have high voltage RF electronics inside, and aren't very serviceable at home unless you really know what you're doing. I'm an electrical engineer and I wouldn't do it myself. – Nate S. Feb 7 at 21:48

    I agree with @NateS. and Ecnerwal on this. I took one apart to use the transformer to make a spot welder. I'm an electrical engineer too and I didn't recognize half the stuff in there. Even if you could determine the problem, good luck getting parts. – JACK Feb 7 at 21:58

    With out a background in electronics very few would be able to find the problem, also there are hazardous voltages in the cabinet yes even unplugged, if the magnetron is bad in many cases it may cost as much as an inexpensive unit and is the power supply still good. I have a degree in electronics and usually end up saving the magnet they are the strongest you can find other than disk drives. – Ed Beal Feb 7 at 22:09

    I'm voting to close this question as off-topic because appliance repair is not in-scope here. Unfortunately it's not really in-scope on other SE sites, except possibly ee.se sometimes. I would ask in their chat once you have a specific enough question. – Harper - Reinstate Monica Feb 7 at 23:33

Your microwave likely has a shorted transformer, magnetron, or rectifier diode, and should be repaired by an appliance technician if it is expensive enough to justify the cost. If it is inexpensive, then not only can it be replaced cheaply, but repair parts for inexpensive microwaves are likely not available in the first place.

  • Most of the ones I have worked on had magnatron or power supply problems rarely do the transformers them selves go bad but the diodes and fuses do fail when the “tube” or magnatron fails or is shorted because of a reflection back into the the tube (normally caused by metal). Of these I have fixed a few but the tube itself is harder to get as transformers are usually easy to second source. After reading your comment I felt this was worth a down vote. This site is not for ripping others comments, I explained what I had said in a comment then noticed additional comments.- – Ed Beal Feb 7 at 22:57

    You didn't like my comment under the question, so you downvoted my answer? That doesn't make any sense, as the proper course of action for a comment you don't like would be to downvote the comment itself. Anyhow, I did forget about the newer high-frequency switching microwaves that would have rectifier diodes near the mains, so I have updated my answer. – Hitek Feb 7 at 23:12
  • The root problem is the question itself has serious issues; appliance repair questions are off-topic for reasons. That makes the discussion and answers fruit of a poisoned tree: impossible to be good. The first 3 comments erred by presuming "cheap", but your comment was out of line. Separately, your answer doesn't work because a) the question can't be answered well, b) it's a "Hire a Professional" answer, and c) because of a) it doesn't answer the question. – Harper - Reinstate Monica Feb 7 at 23:44
  • @Harper-ReinstateMonica - I agree with everything you said. Sometimes it takes me some time adjusting to the style of an SE that I don't often visit. I don't mind deleting the answer if it is the appropriate thing to do.... – Hitek Feb 7 at 23:59
  • @Hitek Acknowledged. I have a feeling the question will be closed, so I'm not sure what to advise to do. – Harper - Reinstate Monica Feb 8 at 0:12
