    Are they on the same breaker?

    They shouldn't be. A microwave should always be on its own breaker.

    Is it actually ever smoking?

    This was a model introduced in about 2000, so it almost certainly does not have the power line filter now required on microwaves.

    So it may be outputting electrical interference via the power line.

    I would try a power strip which has a noise filter, and be sure it is rated at 15 amps or better.

    Let us know what you think once you've looked this over.

SOURCE: my microwave says "child" and won't play anymore

Not sure of the TT series models but for the NN series models the procedure is as follows:-

If "Child" is displayed in the display window, then the child safety lock is on.

To remove the child safey lock, press the "Stop/Reset" button 3 times in fairly short succession (less than 3 seconds). The time of day or just the Colon sign (:) is then displayed

If you later want to apply the Child safety lock, then, when the time of day (or colon sign) is displayed, press "Start" 3 times (again in short succession).

Hope this helps

Panasonic NN-F542BF 1300 watts microwave switches off after 3 seconds


It sounds like you were sold somebody else's problem, it could be a bad magnetron, cracked high voltage diode, and a shorted high voltage capacitor to name a few. I recommend a professional if you feel it is worth getting checked.
