You can find a helpful exploded view here.

The best place to order parts for this brand is Tritronics. Or you can call them toll-free at 866-779-5835. Their Web site will be down until Jan. 2nd.

You remove the bottom cover, then there are two screws holding the motor in place.

NOTES ON REPLACING TURNTABLES & 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: Hello, I have a Panasonic

Check the door switch and once the door is shut the board must be active. If there is no clock or display then the processor board is faulty. Also if there is no action from the touch pad then it must be checked. Since the turntable works as you start the processor seems to work but the output to the magnetron is not active. So you need to check the relay to the magnetron switching, check the temperature cut off unit and the main capacitor.
All the above seems to be suspected.
Attempt with care/caution as there is high voltage present.

Panasonic NNA873SB, turntable is no more turning

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.

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

Change Motor but turn table does not turning?

test the following steps and fix it. God bless you

Turntable Motor

If the microwave turntable doesn't turn the turntable motor might be worn out. This is a common problem and relatively easy to replace.

Touchpad and Control Panel

If the microwave turntable doesn't turn the touchpad and control panel might be defective. This is not common. Test the turntable motor first.





Touchpad

If the microwave turntable doesn't turn and the touchpad has a button to turn the turntable on and off the touchpad might be defective. Check the turntable motor first, that is more likely.





User Control and Display Board

If the microwave turntable doesn't turn the turntable motor might be worn out. This is a common problem and relatively easy to replace. If the motor is good, the user control and display board may be defective.




Main Control Board

If the microwave turntable doesn't turn the turntable motor is usually the problem. If the motor is good the main control board might be defective

Panasonic nn ct766 turntable locked

If everything cooks as normal but the turntable does not turn then I would say that either the turntable motor has failed or the supply for the motor, either way this is not a problem you could fix yourself & so I would recommend taking to a microwave repair centre or service engineer.

Goldstar under counter microwave spindle won't turn

use the common sense, and logically, fix it. God bless you
Microwave Runs, Heats, but turntable does not move This is a fairly easy one. 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.

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.

I have a GE spacemaker XL over the stove microwave oven. Its 10 years old. The turntable quit turning. If I take the glass turntable off and put a glass of water inside, the motor will turn - sometimes...

This is a common problem in many brands, you have proved the AC voltage to the motor is fine, if there had a been an issue the voltage would have dropped while in operation causing a load on the power supply, since there was no change in the off/on stage it proves the motor is the problem and must be replaced to resolve the issue.
