Garage door opener trolley does not reconnect to the door after pulling the emergency release.

Safety first: Ensure the door is fully closed or securely supported before attempting to reconnect the trolley.

• Reset trolley: On Craftsman openers, pull the red emergency release cord toward the opener head to reset the latch into the engaged position.
• Run opener: With the door closed, press the wall button. The trolley should move and automatically reconnect to the door arm when it reaches it.
• Inspect latch: If the trolley passes the door arm without engaging, inspect the latch mechanism for broken plastic or bent metal. Replace the trolley if damaged.
• Check alignment: Ensure the rail is straight and the door arm is properly aligned with the trolley path.
