In most cases, this is 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. You can find one here.

We're happy to help and we appreciate your thoughtful rating of our answer.

I see. Okay, well then I would expect there's a problem with a high voltage part, such as the diode, magnetron or transformer.

Your model number should be entered as JVM192002 and you can find exploded views here.

You can usually find GE parts for much less here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

Likely takes a torx wrench or some other special star tool to open it.

Could be a bad relay a bad mag tube or a bad timmer or a bad door switch. Needs to be trouble shooted. You have to get it open and check the fuses and test the voltage on the pri transformer first.

SOURCE: NNC2000P - Microwave does not work but convection works

An IGBT is an insulated gate bipolar transistor - sort of a hybird between a bipolar transistor and a MOSFET.

These are the final output driver transistors in the high-voltage inverter.

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

It's likely a bad transistor, an electrolytic capacitor with an internal short or bad ESR or altered value, bad connection on the inverter board, a shorted diode or blown resistor, or a bad connection in the wiring.

Reputable service centers will have a repair warranty, but it may only be 30-90 days.

Due to the lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

You should use a Panasonic-authorized service center so they'll have the service manual and (hopefully) experience and training to repair inverters.

In the US, you can find an authorized Panasonic servicer here.

This sounds like a non-US model. If so, visit panasonic.net, find your home country, then find the service / support links.

SOURCE: sharp R-1871 microwave/convection oven. Microwave will not work

This may be due to the microwave section not working. Check the high voltage diode if it is ok, replace the Magneton.

Check the 20 amp fuse where the power cord ends inside the oven. If it is open check the latch switches. If the switches check ok the invertor is probably bad, smoking.

There will be a reset switch button on your microwave's timer or somewhere on the appliance. Try the button and if it doesnt work then call customer care. It seems like a minor problem and can be fixed quickly..
