Chances are there are other bad parts blowing the diodes, most likely a MOSFET.

Also, the ESR of the electrolytic capacitors should be checked and all board connections must be checked and resoldered if suspect.

If you're not experienced in troubleshooting switched-mode power supplies (inverters) then you can probably save a lot of timer and money by replacing the whole inverter.

You can find the nearest spare parts supplier by selecting your country then the support links at Panasonic.net.

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

Test the high voltage capacitor, the rectifier diode.or the magnetron.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

I can't seem to use the microwave function on my Panasonic Grill and Convection Microwave Oven NN-C784MF. It turns on and spinning but doesn't microwave.


hi,

they used to have inline fuses on the microwave circuits. open it up and check for inline glass fuses on the board and inline to the magnetron primary circuits, use caution theres a capacitor with a stored charge in the secondary circuit.

Panasonic Oven model No NN-C784MF/WF


I would keep the items in. Usually, oil is sprayed on which can cover anything that is in oven at that production step. Won't hurt anything one way or the other.

Hi, my panasonic nn-c784mf stop spinning, seems like the bolt at the center is stuck. Any solutions? Thanks!!!


If you are talking about the turntable with the glass plate that is not working. It is caused by a defective turntable motor, the only solution is to have it replaced, but considering prices as they are probably better to replace the microwave oven.
