Opener beeps or flashes but does not move the door after a power outage until limits are re‑set.

Safety first: Ensure the door path is clear before re‑learning limits.

• Step 1 – Perform factory reset: Follow the B&D manual to reset the opener to factory defaults.
• Step 2 – Re‑learn travel limits: Run the full open and close limit learn procedure.
• Step 3 – Check backup battery (if fitted): Replace the memory/backup battery or full backup pack if the unit uses one.
• Step 4 – Surge protection: Plug the opener into a quality surge‑protected outlet to reduce future corruption from power spikes.
