My GE Profile Model PEB7227 microwave makes a lot of rattling noise when running. I removed the glass turntable and it still makes the noise. I tried shooting a few drops of silicone oil into the area where the plastic thing-a-mabob fits tht drives the turntable and it still makes a horrible rattling noise. So, at this point I belive the drive motor is defective. The unit is only a little over a year old but is out of warranty.
Any suggestions on how to replace the motor or where to get the repair manual?
