Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part

Whirlpool mircowave making grinding noise


The grinding noise could be from the turntable motor, or the fan. Remove plate from oven and put a cup of cold water in, set for 30 seconds and run the microwave, if no grinding is detected it means the turntable motor is near end of life. If there is no change unplug microwave and remove top check the fan mounts tighten if loose, if straps are tight suspect the fan motor.

Phillips microwave oven vt255/bl tuntable does not rotate


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.

GE Spacemaker Microwave Oven Model JVM1440BD: turntable doesn't work. When we press start, turntable make semi-loud noise while oven is cooking, but it does not turn. We can stop noise by pressing...


The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it 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 can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Dacor PMOR 30SS 1100


jamison665 was you using the microwave when this happened? Reason I ask is that all microwaves over the range have a temp sensor so if you are using the cooktop and don't have the vent fan on the OTR running, it will turn on the fan if it gets to hot. Once this cools off, the fan will quit running. When this happens, it is only the fan that is running. I think this may be it since the turntable will rotate when the mircowave cooking section is in use.
