The turntable on my NN-A554 microwave won't rotate, could it be the belt?


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.

Microwave (Panasonic NN-S254BF) starts, runs 2-3 seconds, and then shuts off. I have checked the door latch switches, and they are all working like they are supposed to. Whats wrong?


In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

Panasonic NN-S254BF microwave oven runs for 2-3 seconds and then shuts off'


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 4yr old NN-S262SF OTR runs for 2secs and stops whenever start


Hello

Microwaves use alot of power and should be on their own 20amp circuit. Get an electrician to put the microwave on its own circuit.

Our microwave oven Panasonic NN-S252WF stops after


Our technician suggest that there may be a problem with the Inverter Board in this model, which is something that would need to be looked at by a Service Center.

In rare cases it could be the door switches.

Panasonic NN- A712 combination Microwave 1000w - Switches off after 20 seconds


The 22 seconds is the giveaway.

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.
