Microwave NN-SD697S; Went i push start switch, some time start and some time not, power it fine. thanks for replying

It sounds like you were sold somebody else's problem, it could be a bad magnetron, cracked high voltage diode, and a shorted high voltage capacitor to name a few. I recommend a professional if you feel it is worth getting checked.

my over the range panasonic microwave turns off after 5 seconds????

H95, H97, H98 or H99 mean that there's a problem with your inverter, magnetron, or digital programming circuit.

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

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.

You can find an authorized Panasonic servicer here.

FixYa doesn't notify me when there's a response, so if you have other questions, please contact me directly.

I found sufficient information elsewhere.

My panasonic microwave model # NN-S540BFW stops after 4 seconds after you hit the start button and cuts off on its own. What is wrong with my microwave?

may be magnetron spoiled or high voltage section problem,please check circuit andreplace damage parts...

If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.

Hi,

Yes, you are correct. The membrane switch for this model was discontinued. The correct part number for the membrane switch is A630Y5460HAP for model NN 9859.
