John B Lenoir City , TN April 17, 2015 Microwave turntable making grinding noises when running Watched a YouTube video about changing microwave turntable, ordered the part from appliancepartspros.com, which arrived in only one day. I replaced the motor and now the microwave is quiet again. Thanks for great service. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
