This is not certain, but it may be a part that is expensive to replace according to this other web site for a similar model Panasonic oven. That person said their microwave was still working.

Good day, I have a Panasonic Dimension III Microwave/Convection Oven 1983
Model NE-9910A.

I went to use it today and when I entered to nuk my coffee a FFFF display appeared where the clock normally appears. I went and found my operating instruction booklet and it indicated to "stop/reset" which I did. Next it indicates to contact a Panasonic Servicecenter. Can you help me out? ps. It still works great!!!!!

FFFF means that your display control board has an internal short. The only way to fix the problem is to replace the display control board which is no longer available. If you really wanted to fix the microwave you'd need to remove the display board and mail it to a place like Appliancetimers.com to have the part refurbished. The cost to have the part repaired is usually about $200-250 or so.

I have this NN-C780P Microwave/Convection Oven. The microwave mode is not working and baking was ok until recently, the turntable cannot rotate when the temperature, timing and baking are ok.
When I bake, there are knocking sound.
Please advise.

it's quite a job but replace the drive motor belt under the turntable spindle

To set Demonstration Mode: press micro power once, then press Stop/Cancel 4 times. To cancel Demonstration Mode press Micro power once, then press Stop/Cancel 4 times.

check the damper motor is opening and closeing

Here are is the manual:

Page 13 tells how to shut off Demo mode. (Press FUNCTION-0-2.)

would be a door micro-swtch sharp part # Sharp Part Number: QSW-MA085WRE0

Does this unit have a turntable? If so does it turn when on?

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, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer.
