Warning Signs to Watch For
Catching these early can turn an emergency into a simple scheduled repair:
- The door suddenly feels very heavy or won’t open manually
- A visible gap or separation in the coils of the torsion spring above the door
- The door opens partway then stops, or feels jerky and uneven
- Loud creaking, popping, or grinding during operation
- The door slams down faster than usual or won’t stay open
- Cables look loose, frayed, or have slipped off the drum
What a Broken Spring Sounds Like
When a torsion spring finally lets go, it often makes a loud bang — many homeowners think something fell or a firework went off in the garage. After that, the door usually won’t open, or feels like it weighs a ton, because the spring is no longer counterbalancing its weight.
What to Do (and Not Do)
If you suspect a failing or broken spring, safety comes first:
- Don’t keep forcing the opener — it can damage the door, opener, or cables
- Don’t try to lift a heavy door by hand or remove/adjust the spring yourself
- Don’t attempt a DIY spring replacement — springs store hundreds of pounds of force and cause serious injuries every year
- Do stop using the door and call a professional for same-day service
Why Springs Fail — and How to Prevent It
Springs are rated for a number of cycles (open/close), so normal wear eventually catches up with every spring. Cold weather, rust, lack of lubrication, and heavy or unbalanced doors all shorten their life.
You can extend spring life with regular lubrication and fall maintenance, and if you’re replacing a spring anyway, upgrading to high-cycle springs means far fewer breakdowns down the road.
