When a Haier microwave turntable is not turning, the turntable motor is the most likely cause. Unplug the microwave, remove the glass tray, and use a multimeter to test the motor for continuity. If the motor lacks continuity, replace it. Next, inspect the glass tray drive coupling for stripped or broken splines, then check the glass tray support for damage or wear. Make sure the coupling and support are seated correctly on the motor shaft. If the motor is not receiving power, the Haier user control and display board may be defective, although the motor itself is much more likely to fail. Also confirm that the turntable option has not been turned off, if your model includes that setting. If the motor still has no power, the main control board may be at fault. A microwave not spinning can still heat, but food may cook unevenly because hot spots develop. Enter your Haier microwave model number to find the exact replacement turntable motor, glass tray drive coupling, glass tray support, user control and display board, or control board for your appliance. If any repair requires opening the outer cabinet, remember that the high-voltage capacitor can store a lethal charge even after unplugging. Proper capacitor discharge is required, so use a qualified technician if you are not familiar with the procedure.

04 - Haier 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 - Haier 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.
