Chain drives stretch over time and begin to slap the rail. Tightening the chain, or replacing a worn sprocket, restores a smooth pull and quiets the garage. It is a common adjustment and part of most opener tune-ups.

Garage Door Opener Diagnosis and Repair
One control at a time
Each way of telling the door to move is tried on its own: the wall control, every remote, the outside keypad and, if fitted, the phone app. The pattern of what works tells a story. If the wall button works and nothing wireless does, the receiver, the remote batteries or a lock setting is suspect.
If a remote works only up close, range and interference are the topic. If nothing at all works but the unit's light responds, the fault is downstream of the controls. The technician also checks the wall control's own indicator, which on most models blinks continuously when lock mode has been switched on by accident.
