How to Fix / Troubleshooting
Safety first: Disconnect power before removing the opener cover.
- Step 1 – Remove cover: Take off the B&D opener housing cover to expose the drive mechanism.
- Step 2 – Inspect drive gear: Look for plastic shavings and check the main drive gear for missing or worn teeth.
- Step 3 – Check sprocket: Ensure the chain/belt sprocket is firmly attached to the shaft and not spinning freely.
- Step 4 – Replace gear kit: If the gear is stripped, install a B&D‑compatible gear and sprocket kit, following the service instructions. Re‑grease as specified.
- Step 5 – Reassemble and test: Refit the cover, restore power, and re‑learn travel limits if required.
