Charles R Chapel Hill , NC April 21, 2018 Appliance: Model ME21H9900AS/AA (0001) Turntable on samsung microwave was no longer functioning Opened up hinged bottom of microwave and saw that the old motor had come loose from its secure position. I decided to replace the old motor with the new one and secured it into place, which was very simple--just a matter of unplugging the old motor's connection; plugging in the new one; securing the motor in place with one screw; closing up the hinged bottom; putting in the new coupler; and checking to see if it works. It did! 14 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
