I have a Frigidaire OTR microwave that will not heat. When I press start, the light inside goes on and the turntable rotates, but no heat.

Question edited for clarity.

No you can't. The turntable needs to rotate the food or the microwave energy will burn holes in your food. The rotation spreads the heat evenly throughout the food. You can test it by removing the turntable and put a plate on the base with a pound of butter on it. Microwave on full power for a minute. Notice the holes?

what problem do you have mention ? attached is there a list please indicate. God bless you

No Lights or Power, Unit seems Dead The voltage to the unit is good.Lights come on, but can not program unit, Touchpad dead
Microwave Runs, but no Heat Turntable rotates, acts like it is heating but doesn't. This is the big one, many possibilities.
Microwave Runs, Heats, but turntable does not move
Microwave is arcing
Microwave Vent Hood is not working Over The Range(OTR) Models.
Microwave Stove Light not Working OTR models, light bulbs good.
Microwave overheats and keeps turning off

see this tips for to repair:
Inspect the plastic drive coupling that the tray sits on, as well as the ring-and-roller assembly, to make sure that they're working properly.
First, make sure the turntable coupler under the glass dish is not broken. Second, on the control board, find the turntable relay and test for voltage. Some turntable motors are 24 volts DC, so make sure your testing the correct voltage. If no voltage from the control board, then replace the control board. Otherwise head towards the turntable motor.On OTR models, you can get to the motor by un-screwing the bottom panel on the microwave. On countertop models, there will either be a knockout or screw on access panel. Check for voltage at the motor. If no voltage, check the wiring back towards the control. If voltage, then replace the turntable motor. The component list below also shows how to test a turntable motor.

When you press the "Start" pad to begin cooking, do the inside light, cooling fan, and turntable ALL come on?

If not, which do and don't?

Is the oven louder or quieter than usual?

may be a shorting door switch and/or wiring to it.

1. the motor to rotate the glass table in the micro wave may have stop working or the switch to the motor is defective.

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

Here is 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.

But if you've recently had trouble with the cooktop lights, then the control board may be damaged.

We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in about a week or so with a one-year guarantee.

We have a similar problem! It sounds like a problem with the microswitch inside the unit that the door is suppose to engage when closed. If not engaged properly, it will not cook. We had the switch replaced last March but it has started acting up again. We can press in on the door and/or lift it slightly and it will cook. Try putting time on the counter and hit start. It the word "cook" appears then try moving the door slightly and see if the turntable starts turning. If not, then you may have a more serious problem. Good luck!

When you enter the time and press Start:

Does the inside light come on?

Does the turntable rotate?

Do you hear the internal cooling fan running?

Does the time count down?

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.
