My theory is that when the entire shaft moves it causes some gears in the gear motor section to not line up properly. So the cam won't turn, which means feeder bar stops feeding. But I've never taken it apart to see if that's accurate. 8 years is a nice run on that motor. I won't mind buying another one if it lasts 8 years.
Not my style stove here, but try that motor plugged straight into wall socket w/o the controller and see what happens.
The magnetic state of the motor should be strong enough to raise that sagging motor and run perfectly free...if by plugging motor in direct it works then you need to look to the controller for your trouble.
