    out of nowhere, my microwave has started tripping the circuit breaker in my main breaker box. It's on a dedicated breaker, nothing has changed electronically. It's not old

    Background: had my kitchen completely remodeled 3 years sgo, all new appliances, all new wiring & breakers. The contractor was awesome & he did excellent quality work in all regards.

    What are potential causes? What should I do to troubleshoot?

    Thanks in advance

    I think it really could only be one of a few things:

    1) the microwave is bad, has a short in it somewhere, going bad, etc... - doesn't matter how old, electronics aren't built like they use to be :) - most likely
    2) bad circuit breaker - it's true, this does happen from time to time.
    3) there's something wrong in the wiring - prolly the least likely

    If it is knocking off the kitchen circuit, take it to another location in the house and plug it in and see if it trips that circuit. If so, sounds like a bad appliance.

      If nothing has changed the first thing I would suspect would be a bad breaker. Somewhat common, cheap fix.

        Easy answer, get rid of the microwave.

        Just cooking food. It doesn't happen every time, but has happened 5 or 6 times. No consistency. No rhyme or reason as far as I can tell.

        It is not knocking anything else out. It's built in, so I can't move it... but now that you mention it, I can run an extension chord to another outlet, because it is not hard wired, there is an outlet inside the cabinet. So I can test it on a different outlet! Thanks!

        You need to make sure it's a different circuit, not just different outlet.

          He said it was on a dedicated circuit. I'm still going with a bad breaker. It could also be a loose lug on the breaker or buss bar. Report back after you figure it out.

            Should also make sure that breaker is properly sized for that circuit, dedicated or not, shouldn't he?

            Edit: And Gren already spoke to it :lol:

              I can't believe how crappy breakers have become in last 5-10 years. I thought I had a water heater issue. Turned out to be a breaker put in about 4 years ago as part of remodel. Replaced it with new breaker... that was bad out of the gate! Got second new breaker, no problem since. Light bulb quality is crap too... I can't tell you how often I have little 45w floods go bad.

                Did you figure it out or do you need me to provide an opinion?

                I'd like to hear what you have to say...
                In the meantime make sure you always follow the instructions:

                also check the cable connection at the receptacle to make sure the screws are tight.

                I'm with Cooter on it being a bad breaker. I've also seen a random garage outlet tied into a kitchen outlet without no one ever knowing till something like this happens.

                I'd also question the micro cord.

                  By code, all garage outlets are supposed to be on a gfi (except the door operator)

                  Good point on the remodel/double up on the breaker possibility. Metro Atlanta required it and basements on gfi since the early nineties so I just kinda assume it. Biggest problem with that is people like to keep a fridge or freezer in the garage and if it trips you suddenly lose a lot of food.
