    Got a question for all you home electrains out there. My microwave started turning off whenever you turned it on. This happens only when it is plugged into the outlet behind it. If I unplug and plug into a different outlet then it works fine. The curcuit breaker for the outlet behind it does not trip. So I figured it was a bad outlet. I replaced it today and the microwave still shuts off when I go to use it. I can plug a light into it and it will work all day.......any ideas???? HELP!!!! This is driving me NUTS.

    More information please:
    1) Are the two different outlets on the same circuit?
    2) What else is sharing the circuit with outlet #1.
    3) What's the power requirements for your microwave?
    4) What is the circuits amp rating (15A, 20A)?
    5) Does a little buzzer/bell go off when the microwave stops? [​IMG] [​IMG]

    Since you replaced the outlet already, try this:
    With nothing plugged into the outlet, measure the voltage. It should be 120V or so. Then, go to a different circuit and measure it. Note the difference, if any.
    Then, plug the light into the bad outlet, and check the voltage at the outlet while the light is on. If it drops more than 0.5volts (assume a 60W or so bulb), then you must have a loose connection somewhere, causing a high resistance point. These are the types of intermittent connections that burn houses down in the middle of the night. Find it!

    I'm stumped. If it's a 1400 W oven that should be maxing out the 15A breaker and the breaker should be tripping. You don't have to reset the breaker? Hmmm.
    I went through this recently. I installed a new microwave/hood combo in the kitchen in place of just an old hood. I didn't know it at the time, but the new 1000 W oven was sharing a circuit with the kitchen lights, garage lights, outdoor lights, and 1st bedroom lights and outlets. The 1st bedroom has a computer in it with a 300 W power supply. So when everything was on and we ran the microwave...*Pop* goes the breaker!
    So I installed a new 20A circuit and ran new 12awg wire to the microwave. Works like a champ now.

    1400W/120V= 11.67amps. Unless there are heavy loads elsewhere, the breaker wouldn't trip.
    I've got a similar setup in my house, and never had any issues with it. My house is fairly new, though- 1994.
