How to Fix a Craftsman Garage Door Remote That Won't Work
- 1). Replace the battery in the remote control if the remote control doesn't work.
- 2). Check for obstructions at the door if the remote control is erratic. For example, the door will not close or reverses suddenly and the lights blink on the motor unit.
- 3). Reprogram the remote control. Press the learn button on the motor and release it. Within 30 seconds, press and hold the button on the remote that you are having a problem with. Release the button when the motor unit light blinks.
- 4). Test the remote control.
