If your Craftsman garage door opener emits a repetitive clicking sound from the motor unit or logic board but the door refuses to lift, the problem is almost always caused by a tripped relay switch, a stripped internal nylon drive gear that is slipping on the motor shaft, or insufficient motor power trying to lift a heavy or bound garage door. Additionally, binding garage door tracks or broken torsion springs can overload the motor. Callout type="warning" title="Safety Warning": High-tension springs store lethal force; never adjust or repair springs without proper winding tools. Verification: Disengage the manual release and test the door by hand to ensure mechanical balance and smooth track movement.
