Question about Panasonic NN-S553 1350 Watts Microwave Oven

2 Answers

MW stops after 23 seconds.

Sir, On any power level the unit turns off after 23 seconds. There is no heat and I can restart it as soon as it stops. The fans and turntable work fine. I do not think the door switches are the problem since "the diplay clears and returns to clock mode" like it is finished cooking. When this occurs ther is no beeping like it was done. I checked the switches with a Fluke and they are working fine. Normally if the MW is stopped the cook time remains on the display. There are no strange noises or odors. I hope this enough info for you go on. Thanks Jay Johnson

Power on but no heat

see the next step:God bless you
Microwave Runs, but no Heat OK, get ready, this micrwave oven repair can take some time. This is where you must be able to read a wiring diagram and do some "live" checks on parts. First easy check is to make sure power is coming off your control board at the MW relay. Make sure of the wires and test here, if you have 120 volts at this point, you have ruled out a lot of parts that could be the problem. You have now ruled out any switch problems, control board problems, or a thermostat or 2.
If you do not have power from that MW relay on the control board, you must trace the wiring back to see if the proper voltage is going through your switches, any thermostats, and arriving at your control board. Your wiring diagram on your sheet will show you where and what to test. Below is a general switch test troubleshooting guide.

Shuts off after 23 seconds....

In most cases when the microwave stops @ 23 seconds it's the Magnetron which has failed, and is shorting to earth.

Either that or the magnetron isn't getting the right signal from the inverter board. It gives it 20 seconds to get the right signal or it shuts itself off.

JVM1850BH02 Microwave completely shut down, not working after...

The extreme heat has opened up one of the thermostats / thermal cutouts (TCOs) in the oven.

If it was the bottom TCO or magnetron TCO, you should be able to access them by just removing the control panel.

But if it's the one on top of the cavity, the oven will have to come out of the wall, then you need to pull of the outer cover..

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

You should locate and look this over first.

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.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Fan & Turntable start when door is opened.

sounds like there is a switch that is bad. you can go buy a new MW for about 200$ and in yours if there is a major problem then i would just go buy a new one but might be worth a repair man to come check it out

pleas do not poke around in the microwave as it carries a charge of 5000volts and can kill you even if not plugged in DON'T TOUCH THE WIRES WITH BRAIDS ON THE OUT SIDE if you must get inside of the unit

Neff HTHB86K Microwave oven.

The microwave unit is faulty as you can read from the display or the controller isn't working correctly, you should take your MW oven to an authorized service center. It can be repaired by yourself but it's highly dangerous because it has high voltage inside and microwave energy.
