SNAPPED, LOOSE, or DAMAGED CABLE
Although cables come in pairs, they will typically break one at a time. You will notice one of your cables is physically broken or frayed, hanging from its drum or coiled on the floor. If one or both cables have snapped or are damaged, both cables should be replaced so both sides of the garage door have equal length of cable. If one or both cables became loose as opposed to breaking, we can put them back on its drum and rebalance your door after fixing other problems that may have caused them to become loose, such as broken springs.
A garage door snapped cable can occur for multiple reasons. Most common reasons may be: Damaged weather strip which can lead to rust on your cable, improperly installed/loose springs, damaged pulleys, or worn out rollers.
If you see that your overhead garage door cable has snapped, unplug your garage door opener and give us a call. Because springs and cables are kept under high tension, you should not attempt this repair yourself. If your door is partially raised, do not attempt to force it up or down. Doing so will further damage your garage door assembly and could cause your remaining cable to snap. A broken cable can leave your garage door unbalanced, unable to operate, possibly hanging at an angle. A broken cable may also cause secondary symptoms in other garage door parts, like the track, spring, or rollers.
