Thank You

Question edited for clarity and add maker.

Panasonic and Sharp are the brand leaders in microwave ovens. The build quality in the old ones is outstanding. I owned a large one in a commercial pub kitchen reheating hundreds of thousands of meal items for 18 years and it never went wrong once!

This is the manual for the 883 model as a PDF file

There is nothing for your model, not even on the Panasonic website.

I would suggest that contact the dealer from whom you purchased the oven or call any number listed on the model tag of the oven.

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 sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

i have samsung microwave CE104VD. suggest how to bake a veg cake. i tried twice but not a tasty result

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.

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

The uPC system is sensing a failure of some type. This could be that the magnetron is not emitting to specificaitions, or one of the power supplies are not operating in specs.

This is not something you can fix yourself. You will have to take the microwave oven to a service center to have an estimate for repair. If the unit is out of warranty, it may not be worth to service.

In case you get curious, I would never suggest for you to open the encosure of a microwave oven. There are very serious safety issues with working in this type of appliance.

Your Magnatron is most likely to have failed, its an expensive part and on a turbo 4 could be 2M236-M42. Unfortunatly this appears to fail due to reduced air flow. So if you do replace it I would clean the rear grills completely to increase the airflow within the oven.
