first, get your money back or get a replacement for no charge. now, unplug the oven for 15 minutes and try again. if no-go, then some device is faulty that only a tech can find

Does the turntable rotate? If everything but this works (except no heat), you probably have a bad door switch. Here's a discussion of what's involved in replacing it: http://www.fixya.com/support/t267796-kenmore_microwave_hood_combination_over

If the turntable does rotate, I'd suspect a more significant failure, such as the transformer, capacitor, or magnetron. If it's any of these, it's time to replace the unit.

You probably have a bad thermistor.

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

(At that site, that part is misspelled as "thermister" for your model).

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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.

Accessing some components for testing will require you to remove the oven from the wall.

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.

Likely takes a torx wrench or some other special star tool to open it.

Could be a bad relay a bad mag tube or a bad timmer or a bad door switch. Needs to be trouble shooted. You have to get it open and check the fuses and test the voltage on the pri transformer first.

SOURCE: NNC2000P - Microwave does not work but convection works

An IGBT is an insulated gate bipolar transistor - sort of a hybird between a bipolar transistor and a MOSFET.

These are the final output driver transistors in the high-voltage inverter.

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

It's likely a bad transistor, an electrolytic capacitor with an internal short or bad ESR or altered value, bad connection on the inverter board, a shorted diode or blown resistor, or a bad connection in the wiring.

Reputable service centers will have a repair warranty, but it may only be 30-90 days.

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

You should use a Panasonic-authorized service center so they'll have the service manual and (hopefully) experience and training to repair inverters.

In the US, you can find an authorized Panasonic servicer here.

This sounds like a non-US model. If so, visit panasonic.net, find your home country, then find the service / support links.

Auto Cook not working


If autocook is not working and everything else it, there is an issue with the sensor in the oven that detects the steam, The emission of steam is what triggers that unit to shut off. If it wont cook on any settings then the issue is with the microwave generator not putting out enough power. This could be from a lot of things.

Microwave plate turner keeps spinning even with door closed and microwave turned off


My microwave is doing this as well; It's a frigidaire model #FGMV154CLFA.

After using the microwave part (it is also convection), the light stays on in the microwave and the turner keeps turning.

And I've only used the convection part of my microwave a couple times and I'm not sure if I was successful. While trying to cook something in convection mode, I pressed convection, then pressed the temp i wanted, then convection, then keyed in the time I wanted the item to cook. The microwave started and the timer started counting down but the countdown stopped with 8 minutes left? I left it alone to see what would happen and it never finished so I restarted the process again.

PS..I've never gotten an error code

Small amount of white smoke coming out of kenmore convection microwave in oven mode


That is usually caused by a build up of fat from microwave cooking on the heating element. It will clear under normal conditions and return if one cooks foods like bacon etc, un covered to prevent splashing of the food that is being cooked.
Hope that helps.

The microwave will only work for 59 seconds then it stops. It is working but only for 59 seconds. I am not sure about the convection oven was afraid to try it. The unit is in our fifth wheel RV. I can heat...


This is a problem in one of the damper-related components, either the switch or motor or the damper door may be binding.

The damper is a door inside that opens or closes depending on cooking mode. If the controller senses that the door is not in the right position, it will shut down the cook cycle.

Sharp models stop after 59 seconds.

See the attached sample drawing for a typical damper assembly.

We have the applicable service manuals for these models and have uploaded them to our site here and here to help you.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

Yes.

In convection mode, you can use anything that's oven safe. Anything you would use in a regular baking oven in other words.

There's a very interesting and helpful article on convection cooking here, and you can find more tips here.
