A microwave is one of the most useful appliances in a kitchen and in a home.  However when even a small problem comes up with it, it may hamper our kitchen routine and makes things difficult for us in the kitchen. One of such issues is microwave turntable not turning. The turntable is that surface on which you place kitchen utensils to heat them up. It is important that it moves so that food can be heated uniformly. If your microwave turntable is not turning, then the following given causes and solutions may prove to be of help.

1. Problem with the turntable motor

PROBLEM: The first and most common reason for microwave turntable not turning is an issue with the motor of the turntable.

SOLUTION: To check this, you can use a multimeter for continuity. To do so, follow the given points:

  • Open the microwave door and remove the glass tray and support ring.
  • Use a screwdriver to remove the screws from the back side of the microwave.
  • Disconnect the wire harness by squeezing the plug and then set the lower panel aside.
  • Now Use a screwdriver to pop the terminals off the turntable motor wires.

2. Glass tray drive coupling problem

PROBLEM: Another common cause for microwave turntable not turning is glass tray drive coupling problem.  The coupling could either be broken or stripped out. Most of the ovens and microwaves have a round glass turntable which is powered by a motor driven coupler as well as a roller guide.  Most units have a three sided coupler which is easy to detach from the motor shaft.

SOLUTION:  You need to gently pull out the coupling off the drive motor shaft in order to inspect the drive coupling for any kind of damage.  If there is damage, then you may need to replace the coupling.

    I broke the turntable of my SMEG microwave – I got a replacement ‘universal’ one for £6 instead of a SMEG one for £35. But the plastic coupling does not reach the pips under the new turntable. If I take the coupling out, can I insert a bit of plastic just enough to raise it to meet the pips, but still leaving enough to engage with the motor underneath ?
