Question about Panasonic NN-S763BF Microwave Oven

1 Answer

Oven won't heat and shuts down after approx. 20 seconds

Everything else is working normally. Light, turntable, controller. For example if you put on 1 minute of cook time and start oven it will count down to 38 seconds and just shut off. No heating has happened during this short cook time.

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter or a bad magnetron.

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

Microwave timer works but will motor will not run/cook.


If everything works on the unit, but you do not receive any heat or possibly the turntable does not turn you have a faulty magnetron (controls heat) and a faulty motor (controls turntable). You would require service on the unit, if parts are available. Some microwaves are so small in cubic foot size, that manufacturer's do not have parts available for purchase/repairs.

Turntable and light won't shut off.


The common cause is one or more bad door switches, or possibily the keypad control board.

The turntable and light won't shut off when not in use


The door switch, one or more are a common problem, or the keypad control board, "less likely"

Shuts off after approx 5 - 7 sec. some smoke


If it stops after 7 seconds, it has a problem with the inverter.

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.

It 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.

Won't heat and turntable doesn't turn


In all likelihood the mangnetron has failed, or perhaps even something in the Power Supply. or a fault that is shutting the system mangnetron 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.

MICROWAVE NOT HEATING


Most likely you have a magnetron problem. Easy to replace (DYI) but make sure the high voltage capacitor is fully discharged first against the case.
