SOURCE: OTR microwave turntable won't rotate

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

If not, please post your brand and model.

It's probably the motor, but possibly the coupler.

One quick check is to remove the turntable and support / roller ring and try to turn the coupler. It should be a little hard to get started, then you should hear a whirring sound, not a clicking or grinding, which would indicate a bad motor.

If the coupler turns loosely with no resistance, then it's probably bad.

Here is my text on replacing couplers, which had steps which are necessary when replacing motors. Note that if yours is a built-in model, ignore the part about turning it on its side *grin*

NOTES ON REPLACING TURNTABLE COUPLERS

Copyright 2007 by William E. Miller - MicrowaveDisplay.com

UNPLUG THE OVEN FROM THE WALL FIRST OR YOU WILL EXPOSE YOURSELF TO LETHAL VOLTAGES!

Note that I am not encouraging you to work on electrical items if you are not qualified, and I assume no liability for any consequences of your decision to do so.

When replacing the turntable coupler on most models, it is necessary to loosen or remove the screws that mount the turntable motor to the bottom of the chassis.

It is usually easier to do this with the microwave oven on its right (heaviest) side because you will need two hands for alignment.

Be sure to put a towel or similar cushion on the work surface to avoid scratching the oven wrapper (oven cover) or the work surface.

It is not necessary to remove the wrapper or the wires from the turntable motor itself, but you may need to remove a small metal duct covering the turntable motor if your oven has one.

It should only be held on by one or two screws.

Although a broken coupler may come out easily or even fall out, the new coupler will not go in without at least loosening the turntable motor.

Look at the hole in the new coupler. You'll notice it has (most do have) a flat side to it. That flat side will line up with the flat side on the motor shaft.

When the old coupler is out and the motor is loose, you can ease the new coupler in the hole with one hand while turning the coupler very slightly back and forth as you gently push the motor toward it. Do not force the part in.

When the coupler has mated properly with the motor, you should feel it go in.

Be sure it's right, or you may break the new coupler or bend the mounting ears of the motor when you attempt to tighten the screws.

Reassemble in reverse order.

SOURCE: Panasonic Microwave Turn table rotates when door is open

Found this Panasonic post in the Samsung section!

If it moves just a tiny bit when the door opens and then stops, that's normal.

If it keeps running when the door is open, that's usually due to a bad door switch or broken / loose door switch mount.

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and
disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

SOURCE: Panasonic Microwave NN-6453B Turntable has stopped

(Does the control panel allow it to be turned off and on? You can usually find the owner's manual here.)

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

If yours 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. You may have to cut the cover off with snips, then use a screw when reassembling it.

Turntable will not revolve


Hello

Inspect the turntable base wheels and guides. If they are gummed up with food or other gunk, they will not turn and the turntable will not rotate. Clean as needed.


Remove the microwave case by unscrewing the casing screws with your screwdriver. Locate the turntable motor which will be directly beneath the oven floor.


Inspect the belt that connects the motor to the rotating table. If the belt is broken, replace it.


Touch the probes of a continuity tester to the electrical contacts on the motor. If the tester lights up, the motor windings are good, which means the motor is functional. If there is no light, the motor needs to be replaced.

Check the wires leading from the cord to the motor itself. Look for any breaks in the wire, or a wire that has been pulled off of any electrical connection. Any connection that has been compromised can be soldered back into place, but if the cord is damaged at all, it needs to be replaced.


Attempt to spin the motor by hand if the continuity is good and the belt is in place. It should spin freely, but if it is difficult or doesn't move at all, you will need to lubricate the bearing. Either apply spray or bearing lube to the motor axles to solve this problem, and allow the motor to spin freely once again.

Phillips microwave oven vt255/bl tuntable does not rotate


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.

Thanks.
