Griding Sound From Microwave when Running

First had to figure out where the sound was comming from. Took off the bottom cover and saw the Glass Cooking Tray Drive Motor. I had to take the motor off and turn the microwave on to verify that was where the sound was comming from. Apparently the microwave itself was amplyfing a slight grinding that was comming from the motor. I ordered the part; Only took 48 hours to receive the part! Swapped the motor out in 10 minutes and saved $300 for a new microwave.
