We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.

At our site, we now have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

This failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa.

Feel free to contact me directly (and please remind me of your model number) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

I have a NNSD297 Panasonic over the range microwave oven. First the unit had power, clock , timer, fan was working; except after hit the start button, maybe 2 secs looked like working then stops operating....


Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides. If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean, solder and reset the board. Now identify the parts by clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.

The SE indicates a short in the keypad membrane, but to cure this! the whole keypad control board should be changed if effort to resolve is decided, I would also suggest checking the pricing.

I would strongly consider replacing the microwave oven, prices have dropped considerably. The problem you are describing is in the keypad controller board.

Buttons on microwave do not work at all


Yes. The time base is important.

You could unplug it and try it again, but it may not work.

Another model's manual says, "a 120 Volt, 60 Hz,
AC only, 15- or 20-amp fused electrical supply (or circuit breaker)
is required."
