Signs that spring service may be relevant
Report whether the door became heavy suddenly, whether you heard a snap, whether a spring has a visible gap, and whether the cables or door position changed. These observations are useful without claiming that a specific part has failed.
- Door is much heavier than usual
- Opener runs but the door stays down
- A spring appears separated or damaged
- Door will not stay in its normal position
Leave tensioned hardware alone
Garage door springs store mechanical energy. Do not wind, cut, remove, or substitute a spring based on appearance, and keep people and vehicles clear of a door that is not moving normally. If the controls are the only problem, the opener-repair page may be a better starting point.
