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).

03 - Touchpad
The touchpad 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 is defective. To determine if the touchpad is 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.
