Most likely the power capacitor is shorted.If you know someone that is just alittle familiar with electronics, they will know what to look for.The part will look like a somewhat long large silver 9v battery with two metal leads.Normally toward the back of the microwave and below the cooling fan.With a volt-ohm meter this capacitor can be checked.on the meter if you get a reading ,its bad, if you get no reading(open), its most likely good.Ninety percent of the time it will be bad.If it is, just replace with the same value and your ready to go.

In most cases, this is a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here.

Thanks for this. Thats exactly what I did. It didn't work at first, however, I think it was my impatience! After selecting the Microwave, you MUST wait until you are told via the screen to input the time. It now works fine. Thanks again. Just needed perseverance! Mike

Shuts off after 23 seconds....


In most cases when the microwave stops @ 23 seconds it's the Magnetron which has failed, and is shorting to earth.

Either that or the magnetron isn't getting the right signal from the inverter board. It gives it 20 seconds to get the right signal or it shuts itself off.
