I assume this is Whirlpool model GH4175sp?

This answer also assumes that yours does not allow for keypad control of the turntable.

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.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

We're happy to help and we appreciate your thoughtful rating of our answer.

    I might also ask if you've had trouble with the stovetop lights recently?

    Oh okay, maybe I misunderstood. Thanks for clearing that up!

    Here's the correct answer:

    This is caused by a loose door switch mount.

    Door
    switch or mount trouble can be caused by slamming the door or by
    opening the door while it's cooking without hitting the Stop pad first.

    There
    are plastic mounts inside the microwave which hold the door switches
    and onto which the door latches lock when you close the door.

    The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

    Sometimes
    it's a broken tab on the switch holder, allowing the switch to rotate
    just out of position. Other times, it's a broken tab on the switch
    holder, allowing the switch to rotate just out of position. This tab
    can be hard to see, since it is under the bottom edge of the switch.

    If
    you or someone you know decide to look into it, we have critical
    information on safety, disassembly and door switches at our site, and
    our link is at our listing here on FixYa:.

I have a frigidaire over the counter microwave and the turntable quit working


Good Afternoon Friend, I appreciate your post!

If the turntable of your Frigidaire microwave has stop working, often the possibilities include one of three culprits:

  • Power Supply
  • Turntable Turned Off
  • Turntable Support Damaged

I always recommend resetting your microwave first before reaching out to a professional. You can do so by unplugging your appliance or flipping the circuit breaker for about ten minutes and then turn on your microwave.

Best of luck!-Z

Microwave turntable wont turn


Hi - Possibilities of the turntable not spinning are either it is turned off, damaged or the support itself is damaged as well. Confirm that the power supply is not faulty or defective. Contact a professional to move forward accurately.

The turntable is not working but I have power


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.....

Your description seems to be confusing turntable and light do not work
Bulb and motor OK
No power to light or turntable

Which is it?

They could be separate incidents. The drive motor could be fused and the globe just blew its life away..

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.

Turntable doesn't turn


If you just purchased and Installed the microwave, I would call Sears and tell them what is happening, generally, it would still be under warranty if less than a year old. If its a countertop model, you may have to take it in, otherwise they should come to the home for the repair. I would also NOT indicate that you have looked at it as that would void your warranty.
Otherwise, it seems like the problem could be, a) touchpad , b) a relay or c) the main control board
