Garage door opener light turns on, but motor does not run when remote or wall button is pressed.

Safety first: Unplug the opener before opening the housing. Capacitors and wiring can be hazardous.

Steps to diagnose:

• Listen for relay click: When pressing the wall button, listen at the opener for a click. If the light comes on but no click is heard, the relay or board may be faulty.
• Inspect motor wiring: Remove the cover and check that all motor wires are firmly connected to the logic board and capacitor.
• Check for burnt smell: A burnt odor near the motor indicates winding failure; replace the motor assembly.
• Replace logic board: If the motor tests good but the relay does not energize, replace the Motorlift logic/control board.
