If your Roper microwave turntable is not turning, the turntable motor is the most likely cause. Unplug the microwave and test the motor for continuity with a multimeter. If it lacks continuity, replace the turntable motor. A broken or stripped glass tray drive coupling is another common reason the microwave is not spinning, so gently remove it from the motor shaft and check for damage. Next, inspect the glass tray support, also called the turntable roller guide or turntable ring, for cracks or stripped parts. If the motor does not receive power, the user control and display board or main control board may be defective, although the motor is much more likely to fail. Also confirm that the turntable option is enabled if your Roper model allows you to turn it off. This problem may be described as a microwave turntable not working, microwave plate not turning, or microwave tray not turning. Enter your model number to find the exact replacement part for your specific microwave. If testing requires opening the outer cabinet, remember that the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. It must be properly discharged before interior work, so use a qualified technician if you are not familiar with that procedure.

04 - Roper Microwave User Control and Display Board
The user control and display board might be defective. However, the turntable motor is much more likely to be at fault. First, test the incoming power to the turntable motor. If the motor is not getting power, the user control and display board may be defective. If the user control and display board is defective, replace it.
When the microwave turntable turns, the food is cooked evenly. If the turntable stops turning there may be hot spots where the microwaves are concentrated in one area. If the turntable is not turning, confirm the turntable option is turned on (if applicable).

06 - Roper Microwave Control Board
The control might be defective. However, the turntable motor is much more likely to be at fault. First, check the incoming power to the turntable motor. If the turntable motor is not getting power, the main control board may be at fault.
The touchpad and control panel might be defective. However, the turntable motor is much more likely to be at fault. First, test the turntable motor. If the motor is not defective, it is possible that the touchpad and control panel are defective. To determine if the touchpad and control panel are defective, try pressing each of the buttons on the control panel. If some of the buttons respond correctly while others don’t, replace the touchpad and control panel.
