How to Fix / Troubleshooting
Safety first: Disconnect power before removing covers. Keep clear of moving parts when testing.
Steps:
- Inspect drive system: Remove the opener cover and inspect the main drive gear (often plastic) and sprocket. Look for missing teeth or plastic shavings.
- Check chain/belt tension: Ensure the chain or belt is not excessively loose or tight. Adjust per Genie specifications.
- Replace gear kit: If the gear is worn, install a Genie drive gear and sprocket kit for your model. This typically involves removing the motor head and transferring components.
- Lubricate: Apply appropriate grease to the new gear and lightly lubricate the chain (if chain drive).
- Verify door balance: Ensure the door is properly balanced to prevent premature wear of the new gear.
