How to Fix / Troubleshooting
Safety first: Disconnect power and release the door before lubricating or adjusting hardware. Do not adjust springs yourself.
- Check door balance: Lift the door manually. If it is heavy or jerky, the springs or hardware need attention.
- Lubricate moving parts: Apply garage-door lubricant to hinges, rollers, and bearings. Wipe off excess.
- Inspect weatherstripping: Ensure bottom and side seals are not sticking to the floor or jambs.
- Adjust up force slightly: On the Guardian opener, increase the up force one step at a time, testing after each adjustment. Do not exceed manufacturer limits.
- Call a pro if still heavy: If the door remains difficult to lift by hand, have a technician adjust or replace springs.
