A 1/2HP Fimbel Garage door opener. I open the garage door, drove out, tried to close. It did not. Sudden failure, then. Got much closer. I can hear the motor "humming" no movement. Disconnected electrical power, disconnected the belt. The motor is free. The chain is not jammed. I can move by hand. Reconnected - the motors turns. Too low torque?
I can stop the motor shaft by hand (glove, of course) Any idea how to proceed?
Thanks & happy new year
