Garage door opener beeps or clicks but does not move the door; no obvious motor sound.

Safety first: Disconnect power before opening the housing. Capacitors can hold a charge; discharge safely before handling.

Steps to diagnose no motor start:

• 1. Listen for relay: A click from the opener indicates the relay is trying to start the motor.
• 2. Inspect motor connections: Remove the cover and check that all motor wires are firmly connected to the board or terminal block.
• 3. Check capacitor: Locate the start capacitor and inspect for bulging or leakage. Replace with a Stanley-compatible capacitor of the same rating if suspect.
• 4. Motor test: A technician can test motor windings for continuity. An open winding means the motor must be replaced.
• 5. Replace board if relay failed: If the relay is burned or not delivering power to the motor, replace the logic board.
