How to fix the turntable of my LG microwave P/No.: MEZ39996701 that no longer turns while the microwave is operating.

turntable drive may be fouling on cabinet.
Take out the table and see if it is still slow. To centre the drive- take the panel off the bottom, you may have to cut the metal the first time

Is your glass turntable sitting on the rotator correctly? If it is even slightly misaligned it will make terrible noise.

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.

the link isn't real helpful as it all defaults to "have a professional do it"

If a Goldstar, LG or Zenith MV1610 or MV1608 is running but not seeming to heat a load placed in center of turntable, its probably because the "stirrer" intended to spread microwaves generated by the magnetron around the cook chamber is stuck so that most all the heating is directed toward the back and top rather than the center of the cook chamber. This usually occurs after cooking for longer than a minute with no load in the cook chamber - as when a model w/o a timer (such as a MV1608) is intentionally operated in cook mode to serve as a kitchen timer, or when a model with a timer function (such a MV1610) is accidentally operated for longer than a minute w/o any load. Before assuming the magnetron (usually warranted for 5, 8 or even 10 years) or other high voltage component such as diode or capacitor needs to be replaced, try “cooking” a 16 oz pyrex cup of water at full power on the outer edge of the turntable for 2-3 minutes - which usually reactivates the "stirrer" and restores normal cooking function.

If the oven is heting and turntable not turning, then the problem is either the turntable coupler or the turntable motor.

The faulty part must be checked and replaced.

I assume you don't have an illustrated parts list try and Google one up using make and model number etc. It is also a good guide on what needt to be removed and in what sequence.

As far as the novice part, the turntable is a basket case now what can you hurt, this is how we all learned, try to fix it if you cant then call someone who can, not a big deal.

You dont.
You can use spacers(nonmetalic of course) to raise the platter high enough to disenguage the drive. You can also shift the tray to one side on some models.

If the rest of the oven works fine, then this indicates that you might have a problem with the motor that turns the turntable.

If you try to turn the turntable manually (gently), does it turn freely or is there resistance? If it turns freely, the mechanical mechanism between the turntable and motor may be broken and the motor may be ok.

The oven's microprocessor also controlls the motor. There could be a problem there.

You'll need to have it looked at by a service center. Although its not that difficult to determine which of the reasons I mentioned above is the cause, it can be however, dangerous to operate a microwave oven with the cover off and with high voltage circuits exposed.

Please let me know if I can be of further assistance to you.

Good luck!
