If the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle.

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.

No owner's manual?

If you're in the US, find it here.

If you're not in the US, see Panasonic.net and look for support / download links.

Otherwise, I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

There is an inline fuse that is accessed by removing the outer casing. Follow the power line in to the magnatron and you should see the fuse. Make sure the fuse that you replace it with is the same as the one you removed. If this doesnt work then the magnatron has gone out.

Sometimes when cooking dry foods such as popcorn, potatoes, etc. there can be some reflection back to the magnetron, which will cause overheating.

Try it with about 1/2 cup of water on one corner of the cavity.

That load may be enough to keep it from reflecting microwaves back down the waveguide.

Panasonic Microwave Convection Oven Model NN-8501Vstops after one min. of operation-Display goes to all


If you unplug the ac power cord , wait between 30 and 60 seconds and then replug the cord in, push the reset button and then select the time ot cook desired followed by the start button, it seems to work fine for a while (days) and then for some unknown reason it stops after one minute of operation and returns to all eights on the display. A real mystery as to why this is happening and what is really wromg with the unit.

Microwave runs for 3 seconds and shuts off


This is an inverter-driven model, and this is one way the inverter fails. Often it will tick, too, but the cooling fan may be too loud to hear ticking. If you haven't had smoke, then it may not yet catastrophic. I would bet that a thorough resoldering would take care of it. A good technician can troubleshoot and repair this, as needed, but often they will just replace the inverter. Sometimes that's actually cheaper. Troubleshooting an inverter is way too much for someone without good solid technical experience. I would call a shop and ask for an estimate to replace the inverter. Good luck.
