SOURCE: microwave light door turn table works but does not heat up food

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.

SOURCE: The oven stops partway into the set time, and doesn't heat.

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter, controller, magnetron, or a bad connection from one or the other.

SOURCE: my panasonic inverter microwave model no NN-T523M

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.

Panasonic microwave convection oven model NN-CD997S works normal but stop heating

Judging from the model and without looking it up I expect that unit has an inverter. If it is not the Switches and you have replaced the mag, the inverter is the power supply for the mag to work so either mag not getting power from inverter or inverter not getting signals from main PCB Timer board.

Panasonic Dimension 4 Microwave- Model NN D801. Whilst microwaving for 2 mins on high - heard a zapping noise. Didnt heat food. Front operating panel works. turntable still works. Any suggestions?

A "zapping noise" usually indicates a problem in the high voltage circuit. If it's an inverter oven, it should have provided you with a fault code. If a non-inverter, the most likely causes are a shorted high voltage rectifier or bad magnetron. But there are many other possible causes.

It is actually NN-T695SF, it will not warm food. It powers up then goes dim, then powers up then goes dim, it keeps doing that. Food comes out cold.

Hi, if it is an inverter microwave and the problem is cycling every 2-3 seconds, my experience is the magnetron has most likely gone short circuit and the inverter board is shutting down to protect itself and then restarting, hence your symptom.
DO NOT try to test this unless you are experienced with extra high voltages - the voltages present/stored in a microwave even when powered off can kill you.

Power to microwave but does not cook food

You didn't mention your brand or model number, but I'll assume it's a Panasonic since you posted this under a Panasonic category.

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 and 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.

If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter, controller, magnetron, or a bad connection from one or the other.

Display codes H95, H97, H98 or H99 mean that there's a problem with your inverter, magnetron, or digital programming circuit.

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.

Panasonic Model No. NN-S933BF Microwave Oven

No sorry the issue will be with eiher the inverter, the magnetron or the main timer board. There is a tracer signal that comunicates through these components and if it doesnt get to where it is supposed to go it wil just shut off, the big hint at that is the time interval. It is not something like a sensor heating up and causing a fault. it is not running long enough to get any thing hot it is in the electroincs. Too expoensive to repair, im sorry better to get a new one. Good Luck

Microwave runs 3 sec then shuts off.

mtystufquit - We've already discussed this by chat & e-mail, and if and when you need further help, please let me know.

"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."

ddmdavid - you probably have a bad door switch or door switch mount. Please see these links.

NN-T990SA Panasonic Microwave Stopped Heating

This model uses an inverter to produce high voltage instead of a convential transformer system. While an inverter (switched-mode power supply) is more efficient from a power consumption standpoint, it is more complex, thus more statistically prone to fail. These should only be examined and worked on by someone who has the necessary technical qualifications. Seriously. Often the machine-soldered connections in a microwave inverter are too weak, so they eventually fail, especially if heat is high in the area. They sometimes fail catastrophically. When not catastrophically damaged, you may hear clicking or squealing and may smell an electrical odor, which is sometimes obscured by the cooling fan. Some manufacturers do not encourage or assist technicians to repair microwave inverters. Most offer the inverter as a whole assembly. But sometimes that is actually cheaper than the time and labor required to fix the old one. If a technician is willing and able to troubleshoot and repair the inverter to component level, it will may be expensive, but may be worth it, especially if he or she will resolder and reinforce connections as needed as part of a thorough repair. That could easily make your inverter beter than a new one! You might be able to get some verbal estimates if you call Panasonic-authorized repair shops and ask then specifically about inverter repair and inverter replacement costs for your model number.

Microwave shutsdown after 24 seconds, does not heat up

Classic symptom of a defective inverter. It it's under warranty, you're probably in luck. If not, expect repair costs of about $120-150. If you can find a servider who will repair the inverter instead of just replacing it, you can save some money. If you or a friend can replace it yourself, you'll really save, assuming you follow safe procedures. You can find my file "safety.txt" via a Yahoo search. It is part # A606Y5X00AP for model NN-T993S and runs $62.83 plus shipping. The inverter can be gotten from Panasonic at http://www.pasc.panasonic.com/epartr
