Question about Panasonic NN-S763BF Microwave Oven

1 Answer

Lights up BUT does not cook

My three year old micowave has suddenly stopped cooking.

The digital readout reads normally. Upon typing in the time and heat and hitting the start button, the interior light comes on. The microwave shuts off after only a portion of the designated time has expired and the food or water being heated is still stone-cold. As a side note, there is not any noise to the microwave as there has been during any heating/cooking session.

I've pulled the cover and found that the door switch (behind the key pad) has bubbled and burnt. This switch was cleaned up and tested and continuity is still there. The internal fuse tests good.

I am capable to to the repairs correctly, myself. I just need a little guidance to get the job completed.

Many thanks!

Was there any motor that should run as you turn it on, the fan inside and the rotating table motor. try to replace that micro switch at the door that bubbled out and burnt. try to test or replaced right away the industrial diode that is connected from the capacitor to the ground of the microwave.

Micowave just stopped working


The main fuse in the microwave oven has blown, this is often caused by one or two door switches going bad usually the result of food partical build up and must be replaced to fix the problem.

My two year old Frigidaire Microwave suddenly stopped cooking. All of the buttons work. The lights, the fan, the timer, and even the cooking timer operate. It's just that the light goes on and the timer...


Check the plug. If the vault is 110v or 220v etc.

If the plug seems to be right, but still not
working, you should buy a new one
with a good name brand you can trust.
It's better than paying for repairs and future repairs.

Panasonic nn-s255 wont turn on


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://www.microwavedisplay.com/safety.txt , http://www.microwavedisplay.com/disassembly.txt and http://www.microwavedisplay.com/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.

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.

My microwave keeps blowing the fuse upon hitting the start button


you have one of three problems (H.V. diode shorted or leaky, H.V.capicitor shorted, or the magnrtron tube is beginning to draw excessive current)if thats the case its not usually worth spending that for the mag.,the other two items aren't that expensive

Micowave power


Either the magnatron or the high-voltage capacitor and diode. Replace the capacitor and diode then if still not working, replace the magnatron. Its only affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!

4205 stops after a few seconds, beeps, every segment of every digit lights up.


Sabotaged??? What could they mean by that?? It could be a bad control panel or connection, but I would say you have a bad magnetron, the magnetron is mounted loosely, or the RF gasket (mesh washer) on the magnetron is missing, loose or damaged. I would contact MayTag and see if they have a different authorized servicer in your area, or get on the phone and complain to them in great detail. Do not put up with this, please.
