THE MIROWAVE OVEN IS A PANASONIC SLIMLINE NN-A554 . IT ONLY RUNS FOR 6 SECONDS BEFORE THE LIGHT GOES OUT AND IT SWITCHES OFF

Warm soapy water and a sponge or rag.

Starts and runs for 5 seconds and clicks off and Problem with the Panasonic NN-S963BF / NN-S963WF 1350 Watts Microwave Oven

You require a new turntable motor. Easy enough to fit from underneath the cavity.
Ask a dealer for the turntable motor, they are relatively inexpensive.

Personally I would get a new one just to have it checked out will be over 50.00 in the US

See if this describes what's happening:

• Put in time, push start and unit runs for 2 seconds, relay clicks, unit goes off. Cook time on display goes off and clock time comes back. Bad upper interlock switch and charred connector

If so, see http://207.234.249.73/mwd/safety.txt , http://207.234.249.73/mwd/disassembly.txt and http://207.234.249.73/mwd/doorsw.txt

Otherwise, if the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle.

That may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.

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

my microwave shuts off after a few seconds. is there a fuse that needs replacing?

buy new one magnatron is bad

No sorry the issue will be with eiher the inverter, the magnetron or the main timer board. There is a tracer signal that comunicates through these components and if it doesnt get to where it is supposed to go it wil just shut off, the big hint at that is the time interval. It is not something like a sensor heating up and causing a fault. it is not running long enough to get any thing hot it is in the electroincs. Too expoensive to repair, im sorry better to get a new one. Good Luck

I found sufficient information elsewhere.

The 22 seconds is the giveaway.

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