Turn table in microwave wont turn


Repairs are expensive. New microwaves are cheap. But you don't have to spend a dime on either. If your microwave turntable stopped spinning, here's an easy way to try and fix it. And all you need is some warm, soapy water and your own two hands. You don't have to be an appliance expert to troubleshoot a seemingly broken microwave turntable. You might find that all your little Zappy needs is a checkup and a good, thorough cleaning. If you follow these steps and find that your microwave still isn't turning, it probably means the motor has spun it's last spin. Then it's time to retire old Zappy. Unplug the microwave. Safety first, kids. Remove the glass tray and the circular turntable guide. Wash them both in warm, soapy water to get rid of anything stuck. Pay special attention to the rollers on your turntable guide, making sure they're able to spin freely. Clean the internal cavity. Make sure to check your microwave's center cavity to make sure it's free of movement-hindering (and gross) leftover food. Check that the drive bushing is working. Make sure that the drive bushing, the plastic mechanism in the bottom of the microwave's interior that the glass tray turns on, isn't worn out or split in two. If it is, you'll need to have it replaced. Put it back together. Put the turntable guide back into the circular groove. Place the glass tray turntable over the turntable guide and onto the drive bushing. Adjust until the drive bushing should fits perfectly into the grooves of the glass tray. Test it out. Zap a mug of water for a short bit to see if you fixed the problem. Do not run the microwave without anything in it.

JennAir JMC7000ADW Microwave Oven Turntable not turning


Hello,

Check the turntable guide to make sure it is lined up properly and that there is no debris caught in it. You may need to re-align or clean your turntable guide.

Cleaning and realigning a turntable guide;

Remove your glass turntable cooking tray from your microwave. Gently wash with warm soapy water to remove any debris. Next remove the turntable guide and clean it in the same manner, with warm soapy water. Pay particular attention to the turntable rollers. There could be spilled food particles caught in the rollers, hindering the rollers' movement. Also, gently cleanse the internal cavity of your microwave, paying special attention to the area below the turntable.


With the internal cavity, turntable, and turntable guide completely clean and dry, return the parts to your microwave. First place the turntable guide on the bottom of the microwave. There should be a circular groove in the bottom of the microwave cavity keeping the turntable guide in place. Follow the guide with the turntable cooking tray. Carefully place the glass tray over the turntable guide and onto the drive bushing. The drive bushing should fit neatly into the grooves on the bottom of your glass cooking tray. It may take some adjusting before the tray will sit properly onto the drive bushing.


Test your microwave after this thorough cleaning and realigning in order to determine whether this has solved your problem. DO NOT run your microwave with nothing in it.

CAUTION: Your microwave oven is capable of giving you a serious electrical shock, even when it is unplugged. We strongly suggest you seek the assistance of an appliance repair technician when conducting any microwave oven repair.

Also, Examine the plastic drive bushing the turntable tray sits on. It may have become worn, or even may have split in two;

Drive bushing replacement

Inspect the plastic drive bushing located below your microwave oven's turntable tray. There may be some debris blocking the tray's range of motion. Clean away any blockage you find, and then test your microwave to see if this has cleared up the problem. DO NOT run your microwave with nothing in it.


However, if upon your inspection, you notice that the plastic drive bushing below the turntable tray is worn and/or broken, you will need to have the bushing replaced. Consult with a certified and experienced appliance repair technician. Replacing a drive bushing is a lengthy and involved process that the average layman should not perform.


Good luck.

Microwave lights, clock, and everything works except when you press start, it just counts down like its cooking, but the microwave is actually not on. No hum as usual or plate rotating. It just counts...


Hi, one of the most common reasons why the turntable won't rotate is that the microwave isn't clean. The turntable guide and carousel can get sticky, preventing the turntable from properly moving. If you have built-on food particles or liquids, fill a bowl with 2 or 3 cups of water and 1 tsp. of liquid detergent and lemon. Run the microwave for about 3 minutes. Clean the microwave with a cloth, including the base of the turntable, guide, carousel grooves and microwave base. Your microwave turntable won't rotate if the grooves on the base of the turntable do not sit right on the carousel. Also, check the position of the turntable guide. Place the guide directly under the turntable. Remove the turntable, and then reposition it into the carousel grooves.
Motor The carousel motor is located beneath the base plate of the microwave. If the carousel isn't turning at all, check the motor. Disconnect the microwave from the power source, and remove the turntable, guide and base plate. Try turning the motor to see if it's just stuck. If it doesn't turn freely after a few seconds, examine the motor to see if it's burned out or corroded. Use an ohmmeter to see if the motor has continuity. If not, you must replace the motor.
Bushings The drive bushings are plastic components that sit underneath the cooking plate. Remove the plate, and examine the bushings. Use a magnifying glass if necessary to see if any debris is caught in the plastic. Clean the bushings, and reinsert the plate. Turn the microwave on to see if it rotates. If the bushings are extremely worn or if some of the plastic is broken off, you need to replace it, which is a complicated repair for consumers. Contact a service technician for assistance.

Hi there,

Well first of all you can try to clean the turntable- Remove your glass turntable cooking tray from your microwave. Gently wash with warm soapy water to remove any debris. Next remove the turntable guide and clean it in the same manner, with warm soapy water. Pay particular attention to the turntable rollers. There could be spilled food particles caught in the rollers, hindering the rollers' movement. Also, gently cleanse the internal cavity of your microwave, paying special attention to the area below the turntable. With the internal cavity, turntable, and turntable guide completely clean and dry, return the parts to your microwave. First place the turntable guide on the bottom of the microwave. There should be a circular groove in the bottom of the microwave cavity keeping the turntable guide in place. Follow the guide with the turntable cooking tray. Carefully place the glass tray over the turntable guide and onto the drive bushing. The drive bushing should fit neatly into the grooves on the bottom of your glass cooking tray. It may take some adjusting before the tray will sit properly onto the drive bushing. If further you have the same problem then this could be a failing turntable motor...... Please post comments for further help or information.......

Good Luck!!

The turntable does not turn. How do I change the


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

Microwave turntable won't turn


You may have a tunrtable motor or spindle problem..
This info is from GE website..( link : http://genet.geappliances.com/geasearch/Dispatcher?REQUEST=GETSEARCHRESULT

To minimize the possibility of electric shock, unplug this appliance from the power supply before attempting any maintenance or cleaning.
  • Make sure the turntable is centered and seated properly. On models with a stirrer motor there is a shaft protruding up through the floor of the microwave. Make sure the turntable is securely fastened to this shaft. On models that turn on a ring with wheels attached, make sure the turntable is seated securely on the ring.
  • Check the turntable to make sure it is placed right side up. If the turntable plate is upside down it will drag on the floor of the microwave.
  • Check to make sure that there is no food or debris under the "wheels" of the turntable ring. Food can prevent the wheels from moving forward.
  • Be certain you are pressing a cook function rather than a timer function.
  • If the microwave has a turntable on/off feature make sure the turntable was not inadvertently turned off. Try depressing the turntable on/off pad to re-engage the turntable.

The turntable has a small motor underneath it that rotates the glass tray. You could have a motor that is going bad, or the plastic spindle (what the glass plate sits on) could be slipping. You can access the motor through the bottom panel. Be careful to make sure the microwave is unplugged for attempting any repairs inside. There is potentially as much as 14,000 volts in the high voltage network around the magnetron. Let me know if this helps.
