Question about Panasonic Microwave Ovens

1 Answer

I have a Panasonic Inverter Microwave model NN-N275. The keypad stopped responding to prompts. I unplugged and plugged it back in and tried to set clock. It responded to pushing the clock key but when I set the time and tried to push the clock key again there was no further response on this or any other key.

The first thing 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 maybe an hour. Then let us know if the hard reset does not fix it.

You may instead have a failed keypad.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

If you would like to have us do this for you, we do that for $39.95 plus part costs, which depends on the exact model, one of these:

SOURCE: GE Microwave displaying --F3--

F3 on a GE / Hotpoint microwave means you have a shorting keypad / controls.

There's a chance it can come on by itself and run unattended, which can result in a fire.

So until it is repaired, please leave it unplugged or leave the door open.

On this model, the keypad is not available as a separate part, so you would have to replace the entire controller assembly.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you disconnect the wires and install the new controller.

You can order part number WB07X10903 here for $114.37 (compare that to $174.75 direct from GE!).

When power went off and then came back on, screen on micro wave continually shows demo and I cannot set time


The first thing 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 and try again.

If it still won't work, then you may have a bad membrane keypad / DP circuit.

This not good! from your description the problem is in the keypad controller, on the back of the keypad is a circuit board that contains the microprocessor and additional parts that control vital areas of the microwave oven. The leak has penetrated the vital areas where the electronics are housed, I suggest you replace the microwave oven because the cost will probably more than what a new one will run.

How do I get my Panasonic Inverter microwave out of demo mode? I think my toddler might have hit something to put it in demo!


Hello Two options to try: a) Press the Clock / Timer button 3 times b) Unplug, wait a few seconds, then re-plug to power up with the factory settings. You will need to reset your clock and any favourite settings.
This should work with all Panasonic Microwave models.
Good luck

My panasonic inverter microwave model no NN-T523M switchs off after 5 secondsno matter what setting. the digital screen says consult manual, which has been misplaced


You can find Panasonic owner's manuals here.

The first thing 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.

See if this describes what's happening:
  • Put in time, push start and unit runs for 2 seconds, relay clicks, unit goes off. Cook time on display goes off and clock time comes back. Bad upper interlock switch and charred connector
If so, see http://207.234.249.73/mwd/safety.txt http://207.234.249.73/mwd/disassembly.txt http://207.234.249.73/mwd/doorsw.txt

Otherwise, 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.

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

It may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.


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

You can find an authorized Panasonic servicer here.

In Canada, you can find an authorized Panasonic servicer here.

If you decide to replace your inverter, you can order Panasonic parts from Encompass here or you can call them toll-free at 866-779-5835.

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.
