Question about Tappan TMT104E1 Microwave Oven
When we open the door, the power turns on. When we close the door, the power turns off. In the past, it would start working after opening and closing it a few times. Tonight, we couldn't get the power to turn on when the door closed, and couldn't use it. Help!
You likely have a door switch or mount. See a handy help file on door switches here.

Hi The turntable is operated by a motor under the bottom of the cooking cavity. A plastic coupling that slides over the motor shaft, and that's what turns the turntable. In some ovens the coupling is a separate small piece that the glass tray sits on. Other models use a large wheeled plastic ring that rotates the tray.
The usual reason the turntable stops is that the coupling breaks or wears out. The motor shaft is D-shaped, and sometimes the plastic coupling cracks so it doesn't grip properly. Or the plastic wears so that the opening gets rounded and won't grip the shaft. Then even though the motor is running, the coupler doesn't turn. You can usually lift the coupling off the shaft to check it. In some ovens the coupler can only be removed by taking out the turntable motor.
Another probability is that the turntable motor has failed. In most ovens there is an access panel on the bottom that comes off to get at the motor. You can check the motor with an ohmmeter across its terminals to see if it's good. If the motor checks OK ,you can check for power at the motor when the oven is running. This is a little more difficult because it means there will be AC line voltage present, so caution is to the control circuit board.

Not a problem, but it sounds like you may have a bad magnetron or bad high voltage diode according to this:
"When the microwave won't heat, but you hear a loud buzz, you usually have a defective power diode, high-voltage capacitor, or magnetron. We recommend that you consult with a qualified appliance repair technician for help in determining the problem and deciding..
I hope this will help to solve the problem....
