Opener does nothing when wall button or remote is pressed; no motor sound, but outlet has power.

Safety first: Unplug the opener before opening the housing. Capacitors can retain charge; avoid touching their terminals.

• Confirm outlet power: Plug another device into the same outlet to verify power.
• Inspect power cord connection: Open the opener housing and ensure the power cord wires are securely connected to the internal terminals.
• Check internal fuse: Many boards have a small replaceable fuse. If blown, replace with the same type and rating. If it blows again immediately, there is a deeper fault.
• Transformer and board: If there is no low-voltage output to the wall console or sensors, the transformer or board may be bad. Replacement of the logic board or entire opener head is typically required.
