I feel sorry for you man! Sounds to me like the motor Squee. Did you checked it by turning it by hand? does it spin freely, or do you feel a certain resistance?

I don't think it was the motor. It spun free as can be and just to make sure the motor screws didn't damage the coils, I pulled it apart and nothing was damaged...

No, both were the newer versions...7020 and 9920...
