Garage Door Spring Broke: Do NOT Open It — Here's Why

The loud bang that woke you up, or the door that suddenly won't budge — a broken garage door spring is one of the most common calls we receive. Here's what happened, why it's dangerous, and exactly what to do right now.

What Just Happened — and Why You Heard That Bang

A torsion spring is a tightly wound steel coil mounted horizontally above your garage door. It stores energy — hundreds of foot-pounds of it — when the door is lowered, and releases that stored energy to counterbalance the door's weight when you open it. Your door is not actually being lifted by the opener motor. The opener just guides it. The spring does the real work.

When a spring breaks, it releases all that stored energy in a fraction of a second. That's the loud bang. The coil often whips and partially unwinds. Afterward, your door — which may weigh 200–400 lbs — has no counterbalance. It's effectively stuck in place held by gravity alone.

Why Operating the Door Is Dangerous

If You Run the Opener

Your opener motor is rated to operate a counterbalanced door with its springs intact. Running it against a fully unbalanced door can burn out the motor windings in minutes. The opener may partially lift the door, then fail mid-travel — leaving the door stuck at an intermediate height with a damaged motor. Now you have two expensive repairs instead of one.

If You Try to Lift It Manually

A 200–400 lb door without spring counterbalance is simply too heavy for most adults to lift safely. More dangerously, if the cable on one side is also failing — which often happens when a spring breaks and load shifts suddenly — the door can collapse sideways. This is how serious injuries occur.

How to Tell If Your Spring Is Broken

• ›You heard a loud bang from the garage (often at night when temperatures drop)
• ›The door won't open — either the opener runs but nothing moves, or it's too heavy to lift manually
• ›The opener motor sounds like it's straining
• ›Looking above the door, you can see a gap in the spring coil — the spring has separated at the break point
• ›One side of the door appears lower than the other if you have a two-spring system and only one broke

What to Do Right Now

1. 1Unplug the opener — prevents accidental activation
2. 2Do not attempt to manually lift the door or release the emergency cord while the door is closed — leave everything as-is
3. 3If your car is inside: it can stay there safely until we arrive; the closed door is resting on the ground
4. 4If the door is stuck partially open: call us immediately — this is a security concern
5. 5Call (405) 247-0336 — we dispatch 24/7, same rate at 2 AM as at noon

What Professional Spring Replacement Involves

Spring replacement is one of the most important repairs to have done correctly. It requires safe release of any remaining stored energy in the old spring, proper measurement and selection of replacement springs matched to your door's specific weight and height, installation with calibrated winding to the correct tension, and a door balance test and opener force recalibration afterward.

We always recommend replacing springs in matched pairs — even if only one broke. The surviving spring is at the same point in its service life and typically fails within months of its partner. Replacing both during one visit costs significantly less than two service calls and avoids a second emergency.

How Long Does Spring Replacement Take?

Most torsion spring replacements are completed in 45–75 minutes from arrival. We carry springs in all standard residential sizes on every truck. Extension spring systems (common on older OKC homes) take slightly longer due to additional hardware complexity.
