Panasonic Genius Prestige NN P2956F..replaced light bulb with 35 watt halogen capsule bulb (Philips Outdoor Security 120 V)...light won't turn off (original OEM bulb was 30 watt)

Strange, but it is drawing an extra 5 watts and it is electronically controlled. My guess is that you need a 30 watt bulb.

To cancel Demonstration Mode press Micro power once, then press Stop/Cancel 4 times.

Bulb Replacement in Microwave

You have to take off the case. Need a T20 Tamper Torx bit and a Phillips #2 Bit. There are 2 tamper-torx screws on the case to discourage inquisitive types / prevent untrained hands from entering. Once the screws are out (5 in total), slide the cover off the back. On the right-hand side, you will see the electrics. The bulb is behind the black oval shaped fitting that lies just behind the 2 big red wires that carry the high voltage to the microwave tube. Just pry over the bend-down metal tab, and lift off the black oval, bulb is attached to it. Replace, re-install, and test with case off and door open to ensure your replacement works. Re-install the slip-off case and screws. You're done.

Panasonic microwave touchpad not working

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:

Panasonic Sensor 1250W Microwave cycles off after only 5 seconds.

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 , and

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.

That 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.

The door release button is broken and came off. Need a new door release button

Don't order a new button. Here's what I did. I have had many issues with my Panasonic microwave ovens - the button more than once. I even ordered two new buttons from a reliable source and one of the boxes had the wrong button inside. Today, instead of ordering ANOTHER button, I fixed it simply with a bolt and washer. Precisely: the button is built with two hooks, two prongs, and a central "tube". I used a #10 phillips head machine screw (bolt) 1/2" - 3/4" long and a #8 washer (plus Loctite: optional). You need to open the washer's hole slightly to fit over the #10 bolt. Then simply put the button and spring on the bezel and install the bolt from the rear. The washer will trap the bolt in the bezel, but pass through the frame to operate the latch. panasonic button fix-undefined-undefined-0.jpg

I placed my Panasonic microwave oven OF 1250W into a transformer of a higher voltage the it made a boom sound and stopped working ???any solution

Prepare yourself for an expensive repair. If it is the older style with a large mains transformer, it may be just a blown fuse but the newer switching power modules will have serious issues.

I have a Panasonic Demension 4 The Genious microwave model NE-9970. The unit has worked perfectly for more than 30 years without incident. This morning it tripped the breaker as soon as I pressed start. I flipped the breaker off, then back on, reset the clock and tried again. Same thing. I checked the cord, unplugged it and plugged it back in. Reset the breaker and tried again, Same thing. My girlfriend mentioned that the toaster had been acting up and maybe I should unplug the toaster and try again. The toaster is plugged into a different outlet than the microwave, but I wasn’t sure if it was a separate circuit. So, I shut off the breaker, unplugged the toaster and switched the breaker back on, but this time no display and I could not reset the clock thinking that the outlet may have stopped working I plugged the microwave into another outlet, no display, no power...nothing. I would like to know if there is a reset switch, what the problem could be. I love this microwave and don’t think I could find another like it if I had to have it replaced. Especially since this microwave is installed ina built in cabinet specifically for it. I’m Good at fixing just about anything as long as I have a diagram or manual. Can you please advise me.

That is an odd series of events. Microwave ovens don't have a reset button but they do have a slow blow fuse. It is no point replacing it because you have a more serious short circuit that tripped the breaker immediately. You can't work on Microwave ovens yourself as they are so dangerous inside. Also the case is fixed with special security screws. Panasonic are pretty much the best in the business and I have used many in a commercial kitchens environment. The old ones are much better made than any new one these days, so it is well worth getting it repaired. Pull it out and take in. ..

How do i replace the light bulb in my panasonic microwave oven NN-829BA

  1. Unplug the microwave from electrical power.
  2. Remove all the screws holding the outer wrapper in place, back and sides (note which screws fit in which locations).
  3. From the rear lift the wrapper slightly and it should slip back to release tabs/flaps located along the front. (A putty knife or flat blade screwdriver can help.)
  4. Components inside have sharp edges and there may be considerable residual electrical power retained that can cause injury - proceed with caution!
  5. Inside the component compartment (on the right hand side) and just behind the control panel and door latch assembly you will see the oven cavity light assembly. Check for a bad light and replace as needed.
  6. Exercise caution during reassembly to confirm all wires are in their proper location and nothing is pinched, trapped or otherwise going to cause problems upon reassembly.
  7. Restore electrical power and check operation.

I have a Panasonic microwave showing a H97 code, not working.

Either the magnetron, power board or both have failed.
