Replacing the turntable motor to eliminate the grinding noise is an exceptionally easy task. Just remove the screws on the bottom of the microwave, remove the bottom panel, disconnect the light power cable, disconnect the motor power, unscrew and remove the old motor, and then reverse all steps using the new motor in its place. Important things to note: - The bottom panel tilts down, then lifts up on the back edge to pop out of the slots holding it in place. - Make sure you reconnect the light power cable before putting the bottom panel back in place. Incredibly easy, and now the microwave sounds normal again! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
