Turntable doesn't turn

Sounds like the turntable drive coupling is broken. In the bottom of the microwave where your turntable is, underneath that is a small drive coupling that the motor shaft pushes into. if the motor doesn't turn or the coupling, which commonly has a D shape shaft to keep it from slipping, is broken, the tray will not turn. One quick test it to remove your tray and see if you can turn the coupling easily by hand, if you can you probably have a broken drive coupling. The turntable motor is very difficult to turn by its shaft. so if it turns easily it is probably a broke coupling. NEVER force your turntable around by hand or you can break that coupling.

Take the tray and the plastic piece the tray sits on out of the microwave. There is a small motor that turns the turntable. It is probably bad. You should be able to replace the motor from the bottom of the microwave. Part number is 3966820200.

HELLO.

The turntable is the unit in the center of a microwave that you set your food on. It rotates during the microwave cycle, making sure all parts of a dish are properly heated. These are typically made of either hard glass or microwave-safe plastic.

Your microwave turntable may not turn due to one of these problems explain below



(1)If your turntable is removable (as many are for cleaning purposes), it may have come loose from this turning mechanism.place the turntable properl on the turning mechanism.



(2)If your turntable was previously working and now does not any longer, check the settings on your microwave's LCD display to make sure you haven't accidentally turned off the turntable.


Most microwaves have different settings that the user can select with the press of a button, like a "Defrost" setting or a "Popcorn" setting. Certain microwaves may stop the turntable from turning during certain pre-programmed selection modes. Stop your microwave and don't use a pre-programmed mode. Instead, just specify the time using the number pads and start your microwave to see if your turntable begins to rotate again.



(3)The rotating mechanism on the inside of your microwave that rotates the turntable is actually connected to a small motor on the inside of your microwave's case. If this motor burns out or stops working, the mechanism will stop turning. This is something that needs to be replace.

FOLLOW THESE STEPS TO REPLACE THE FAULTY MOTOR.

THINGS NEEDED.

* screwdrivers

* replacement motor

* specific microwave information and part number


1 Open the microwave door, and carefully remove the turntable tray. Also, remove the frame that the turntable is positioned on. Both the turntable and the frame are not secured in the oven, so removing them is a quick process.

2 Remove the bottom panel of the microwave. The Microwave Wizard website explains that the number of screws securing the panel varies depending on the manufacturer and specific microwave. Once the bottom panel is loosened, disconnect its wiring harness in order to completely remove the panel.

3 Locate the turntable motor. The Microwave Wizard website explains that the motor compartment should be positioned below the center of the microwave. Unscrew the motor, disconnect the wires, and remove it from the microwave.

4 Determine the specific part number for the turntable motor so that a correct replacement can be purchased or ordered. Position the new motor into the shaft in the bottom of the microwave. Screw the motor securely into place.

5 Test the microwave to make sure that the turntable motor is operating correctly. The Microwave Wizard website explains that the motor can make noises if it was not positioned evenly in the shaft. Reconnect all of the wires that were detached when removing the old motor.

6 Reinsthall the microwave's bottom panel parts, and secure all of the screws in place. Reposition the turntable frame in the bottom of the microwave and place the turntable on top of it. Test the microwave in order to make sure that everything is working correctly.

This is commonly caused by a turntable motor that has worn out and needs replaced.

The motor can be replaced by following these steps:

1. Unplug microwave.
2. Open oven door and remove glass tray and carousel ring.
3. Locate and remove the screws holding the bottom panel (under the microwave) in place. With the screws removed, the bottom panel should open.
4. Disconnect the connector plug from the turntable motor.
5. Reach inside the oven and remove the coupler. This is the small plastic piece that the center of the glass tray sits on. You may have to gently pry up with a flat screwdriver to get it to come loose.
6. With the coupler removed, loosen the mounting screw(s) to the motor and it should easily come out from under the oven.
7. Install new motor in the reverse order of the steps I just provided.

This is a very simple repair. A replacement can be purchased at any of the following websites:

searspartsdirect.com
appliancepartspros.com
pcappliancerepair.com
repairclinic.com

Prices vary so shop around for the best price. If the model number you listed this question under is correct, the part number is DE31-10172A. Most of these sites also have helpful exploded view diagrams you can use for reference.

If you have any questions, or require additional assistance, please let me know. I hope this help you.

It sounds like you are talking about the turntable tray adapter in the bottom.
What usually causes arcing is the reaction of the RF (microwave) energy acting on carbon. It's great that the motor and orifice are OK. Sounds like you just need to replace the T/T adapter. If the paint is pitted or altered, you need to use a special catalytic paint for microwave cavities to touch it up. The paint's main purpose is to protect the metal from rust but it is a high temperature paint to stand up to the higher temperature of that environment.

The turntable motor can be replaced by following these steps:

1. Unplug microwave.
2. Open oven door and remove glass tray and carousel ring.
3. Locate and remove the screws holding the bottom panel (under the microwave) in place. With the screws removed, the bottom panel should open.
4. Disconnect the connector plug from the turntable motor.

This is a very simple repair. Ironically, I just replaced mine today. If you have any questions, or require additional assistance, please let me know. I hope this help you.

The following parts are in the turntable system: The turntable motor, underneath the floor of the microwave; the turntable coupler, which is like a small plastic piece; the turntable support, either a three-legged or circular piece with wheels; and the glass turntable tray.

It sounds like maybe your turntable support is missing?

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.
