Turntable Motor

If the microwave turntable doesn't turn the turntable motor might be worn out. This is a common problem and relatively easy to replace.

Touchpad and Control Panel

If the microwave turntable doesn't turn the touchpad and control panel might be defective. This is not common. Test the turntable motor first.

Touchpad

If the microwave turntable doesn't turn and the touchpad has a button to turn the turntable on and off the touchpad might be defective. Check the turntable motor first, that is more likely.

User Control and Display Board

If the microwave turntable doesn't turn the turntable motor might be worn out. This is a common problem and relatively easy to replace. If the motor is good, the user control and display board may be defective.

Main Control Board

If the microwave turntable doesn't turn the turntable motor is usually the problem. If the motor is good the main control board might be defective

Not dangerous, but your food will not be efficiently or evenly heated. To change the motor do the following:-

There is a panel under the microwave, held on by one or more screws. Remove it and you will see the synchronous motor inside. There should be a plug to disconnect the wires. Remove the motor and fit a new one. Ensure that the microwave is disconnected from the wall outlet before attempting any work on it.

Make sure the turntable guide is lined up properly and there is no debris caught in it. Examine the turn table bushing the tray sits on and make sure it is not worn or broken. Make sure the turntable is sitting down in the groove correctly. Lastly it may be the drive motor itself is bad. This is the small motor that turns the carousel. This motor is very difficult to replace and unless you are qualified you should not attempt this repair and leave it to a professional. This motor will cost from $40 to $75 plus the cost of having it replaced. You may want to consider buying a new microwave if this unit is over 5 years old. You could end up spending more to repair this one than a new one costs. Of course you can use it without the carousel.

Sounds like either the turntable motor has seized or that the shaft of the turntable motor has broken off inside the roller ring. You may need to chek with your local De'Longhi repairer.

If you didn't buy the turntable motor then I assume you purchased the coupler ( white plastic/nylon piece that fits into the turntable motor collar and rotates the platen? Is that what you purchased?

Since the company seems to not even offer microwave ovens currently which, to me, is an indication that they are buying and having rebranded some Asian (Chinese or Korean) make and may not even have service information or support.

I checked a site you may not have found that often has info available, Retrevo.

First you need to see if it is the motor that is bad. Usually you find the relay or switch that powers the motor and see if you have voltage.
Microwaves are better left to professionals. A novice could hurt themselves working on a microwave. I would suggest getting a repair man to fix it or buy a new microwave (whichever works out cheaper for you)

I have the exact microwave you do (ems8000w), the motor failed and I found this one worked perfectly as a replacement.

The original is impossible to find.
