Turntable stopped in middle of time-everything stopped-no heat-won't restart-only thing that works is the clock. Turntable will now only turn 1/4 turn each way then stop.

Sounds like the magnetron tube has burned out so you don't get power. It's the heart of the microwave. Time to shop for another, not worth repairing.

You are need a fuse or magnetron.

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.

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.

It's a bad magnetron.

Hi,

Here is a tip that will help you to figure out what is wrong with your Microwave Oven....

Basic Microwave Oven Troubleshooting Tips

The trouble is most likely due to a door switch fault. There are switches operated by the door latch to make sure the door is closed, and they can go out of adjustment or fail. Replacing or adjusting the switch is not a difficult repair, but any microwave repairs should be left to a professional. There are potentially lethal voltages under the cover, and the danger of microwave leakage if the repairs aren't done correctly. If you want to keep this oven, get a repair estimate from a shop. Or consider replacing the oven if it's a basic counter-top model. They are usually under $50, and a repair will probably cost nearly that.

Hope this helps. Thanks for using Fixya!

In all likelihood the mangnetron has failed, or perhaps even something in the Power Supply. or a fault that is shutting the system mangnetron down, for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

if everything works except the heating, it is most likely the mag tube is on its way out.........that is the most common reason for it not too cook.......since the microwave is a GE and it is 3.5 years old, i would say you are better off buying a new microwave, the mag tube starts at around $70.00 and up + the labor it costs too have a service person put it in........around another $60.00

Does the turntable rotate? If everything but this works (except no heat), you probably have a bad door switch. Here's a discussion of what's involved in replacing it: http://www.fixya.com/support/t267796-kenmore_microwave_hood_combination_over

If the turntable does rotate, I'd suspect a more significant failure, such as the transformer, capacitor, or magnetron. If it's any of these, it's time to replace the unit.
