I have a JVM1631 that came with my house. A couple years in, the turntable stopped working. I can manually turn the motor with my hand, but it won't go by itself. Everything else about the microwave works.
Any tips on how I can repair it?

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.
Yes but if you did that then the food would not cook evenly and you would have cold sides as compared to overly warm sides. Its not that it can be turned off there is a fuse that is located up the top if you were to remove the cabinet it would give you access to the fuse but I wouldnt suggest it. Why do you want to turn the turntable off? I await your reply Thank you Rick
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 any of these problems explained below.
(a)If your turntable is removable (as many are for cleaning purposes), it may have come loose from this turning mechanism.place the turntable properly on the turning mechanism.
(b)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.
(c)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 below to replace the faulty motor.
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. Reinstall 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.
There's a turntable motor in the bottom of the oven that drives a turntable support directly in some models, and a plastic coupling that rotates the turntable in others. Turntable motor failure is common, or there could be connections in the power to the motor that have gone bad. Sometimes the plastic of the turntable coupling cracks, and the motor shaft turns but the turntable doesn't.
You can check a turntable motor with an ohmmeter. A good motor will show fairly low resistance (a few hundred ohms or less) between its terminals, while a very high or infinite reading means it's bad. In most models of oven you get at the motor through and access panel on the bottom. Replacement motors for many brands are available, although they're not always easy to find.
It may be more economical to replace the oven if it's a basic counter top model. They are under $50 these days, and a replacement motor might cost $20 or more. Of course, you can continue to use the oven even if the turntable doesn't, you'll just need to turn the food yourself occasionally during cooking.
Two possibilities: either the turntable coupling is broken or the turntable motor has quit. The plastic coupling can wear or crack so it no longer fits properly on the turntable motor shaft. Then even though the motor still turns, the turntable doesn't. Or the motor itself may have stopped working. If the plastic coupling still looks normal and you can't rotate it easily by hand while it's in place, it's probably the motor.
I'm here in the US so I can't suggest where to find parts, but you should be able to locate a supplier who might have replacements available. Of course the oven will still work without the turntable running. You'll have to open the oven occasionally and turn the food yourself to insure even cooking.
1. Disconnect the oven from power supply. Remove the turntable tray, and the turntable support out of the oven cavity. 2. Turn the oven upside down and remove one (1) screw holding the turntable motor cover to the base plate and take off the turntable motor cover. 3. Disconnect wire lead from the turntable motor. 4. Remove the two (2) screws holding the turntable motor and coupling mounting plate to the oven cavity bottom. 5. Turntable motor, Coupling mounting plate and Thermal protection plate bottom will be free.

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.
