Check the Power: Ensure that the garage door opener is receiving power. Check if the circuit breaker or fuse powering the opener is tripped or blown.
Inspect the Wiring: Examine the wiring connections on the motor unit for any loose or damaged wires. Tighten any loose connections or replace damaged wires as needed.
