Most spring failures give off warning signs for weeks before they finally let go. Here's what to look and listen for.

Garage door springs carry the full weight of the door, and they're designed to do so for thousands of open-and-close cycles. But springs fatigue over time, and a spring on its way out rarely fails without giving some warning first. Catching these signs early means a straightforward spring replacement rather than a door that suddenly won't move at all.
If you operate your garage door manually (or notice the motor straining more than usual), a spring that's losing tension is often the cause. Springs are what counteract the door's weight - as they weaken, more of that weight is transferred to the motor and opener mechanism.
Torsion springs mounted above the door sometimes develop a visible gap or separation in the coil before they fully snap. If you can safely see the spring (without touching it - these are under high tension) and notice a gap that wasn't there before, treat this as an imminent failure warning.
This is usually the sound of a spring finally letting go. If you've heard a sudden, sharp bang and the door now won't open, or opens unevenly, stop trying to operate it and call a technician - continuing to use the door can damage the cables, tracks and opener.
On doors with two springs, one spring often fails before the other. This shows up as the door hanging at an angle, or one side lifting faster than the other during operation. It's a clear sign that at least one spring needs replacing, and often both are close behind.
A door that used to glide smoothly but now moves in jerks, stalls partway, or takes noticeably longer to open is another sign of spring fatigue. This is often mistaken for a motor problem, when the motor is actually just compensating for a spring that's no longer doing its job properly.
Avoid attempting a spring replacement yourself - garage door springs are under significant tension and can cause serious injury if handled incorrectly. If you notice any of the signs above, stop using the door where possible and call a technician for an inspection. Most spring replacements are straightforward for an experienced technician and can be completed in a single visit.
