SOURCE: The turntable keeps rotating when the dooe is open - Panasonic T994SFR

This is usually caused by either a bad door switch, a loose door switch mount, or occasionally a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. Other times, it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

We have critical safety & disassembly info (including a how-to video) at our site, linked here.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

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.

Let us know if the hard reset does not fix it.

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 or a bad magnetron.

If you do indeed have a problem, Since it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

I would recommend that you contact your nearest Panasonic-authorized servicer.

SOURCE: oven won't heat and shuts down after approx. 20 seconds

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

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

You can find an authorized Panasonic servicer here.

SOURCE: Panasonic Microwave oven - cooking operation stops afer 2 seconds

Sounds like a short in the microwave circuit. One or more of the following four components has failed -

Transformer
Magnetron
Diode
Capacitor

Repair is not for the amateur, unless you know how to take things apart, and put them back together EXACTLY as the were found.

Parts are available on the Net, and you can get the P/N's off the old components to identify suppliers of the new ones.

Don't try and measure resistance of the diode. It's impedance is far too high to get a good reading. They're cheap anyway. Always replace the capacitor, they're cheap too. No way to test the magnetron, and the transformer is not easy to test either.

SOURCE: My Panasonic Microwave Genius 1300W will not heat

Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

Does the microwave rotate during cooking?

Most microwave ovens have a "stirrer" blade run by a small pancake motor to help avoid standing waves and hot spots inside the microwave cavity. And most modern microwave ovens have a turntable to turn the food, to provide even more even-distribution of heating.

The microwave turning table hasitantly rotates and stops. the Model number is NN-S951BF - manufactures in April 2001

The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

In some brands, you have to cut the motor cover off with snips, then use a screw when reassembling it.

It may be that the wheels on the support may be a bit dry. You can use a tiny amount of cooking spray or cooking oil to try to lube it.

Petroleum-based lubricants are not advised in food preparation areas such as the inside of the oven.

You'll want to be sure the support and the floor of the oven are very clean before applying the spray.

If that fixes it, great, but if it fails again in a short time, then the support needs to be replaced.

You can order Panasonic parts from Encompass here or you can call them toll-free at 866-779-5835.

Oven cooks but turntable will not turn, so it cooks unevenly. How do I reset the keypad so it goes back to normal factory presets, in case I entered something that stops the turntable revolving. Is there...

The manufacturer has set the rotational plate in motion at the same time the microwave tube is energized. They work together as a team. At no time should the plate be idol, unless you remove it completely, and then only the center spindle will turn by itself. It is possible for the rotational spindle in the center of the oven to break, but that is unusual unless some sort of pressure (like stopping it when it was moving) was applied. Also, it has been reported that some individuals tend to put items with too much weight or too large for the oven to manage; thus damaging the rotator. As long as the oven still provides Microwaves to cook your food, it is still OK. Years ago, there were no rotating plates and using the energy was all it took to get the job done. For even cooking, just manually stop the oven at times and turn the food to avoid over heating in one spot.

SANYO EM-D9550. Turntable turns when off but not when cooking.

That's sounds pretty strange!

Since I don't have any service data on Sanyos, I'd have to speculate.

I would guess that one scenario that could cause it would be if the turntable were turned off via the control panel, but there was a switch or switch mount problem.

I would refer you to their support people:

Microwave does not heat food placed in the center of the turntable. Leaves a cold spot in the middle of the food.

This is normal. That's why I always recommend to my customers that the food be placed slightly off-center on the turntable. An analogy I refer to is stirring paint: If you stir paint with a stick by simply rotating the stick in the center of the can, it's far less effective than pulling the stick around an imaginary circle halfway bewteen the center and the edge.
