Garage door is hard to lift by hand?
A properly balanced garage door should lift easily by hand and stay open about waist-to-shoulder height. If it is heavy, slams down, or will not stay up, the springs are losing tension or are mismatched to the door weight, and the opener is straining to compensate.
A properly balanced garage door should lift easily by hand and stay open about waist-to-shoulder height. If it is heavy, slams down, or will not stay up, the springs are losing tension or are mismatched to the door weight, and the opener is straining to compensate.
Common Causes
- 1 Springs weakening with age (losing tension before they fully break)
- 2 Springs undersized for the door weight (wrong spec)
- 3 One of two springs broken
- 4 Dry or binding rollers and tracks adding resistance
- 5 Cables stretched or off the drum
What to Check First (DIY)
- Disengage the opener with the release cord and lift the door manually
- A balanced door rises smoothly and holds at mid-height, a heavy door or one that drops fails the balance test
- Lubricate rollers, hinges, and tracks to rule out simple friction
- Look for a gap in either spring coil (a sign one has broken)
When to Call a Pro
A door that fails the balance test needs spring service, do not adjust torsion springs yourself. A pro re-tensions or replaces the springs to the correct spec so the door is light and the opener stops overworking.
Frequently Asked Questions
How do I test if my garage door is balanced?
Pull the release cord, then lift the door halfway by hand and let go. A balanced door stays put. If it slides down or feels heavy, the springs are weak or mis-sized and should be serviced.
Why does a heavy door matter if the opener still works?
The opener is compensating for the springs and will wear out years early, plus a poorly balanced door is harder to operate in a power outage. Correct spring tension protects the opener and the door.
Can I adjust the springs myself?
No. Torsion springs are wound under extreme tension and adjusting them without the proper bars and training causes serious injuries every year. This is a pro-only job.
