Garage door off track or a cable snapped: stop and read this first

What you’re seeing and hearing

• A bang, a metal-on-metal grind, then a door stopped at the wrong angle: one side higher than the other, a roller hanging where the track should hold it. Source: Garage door off track: causes and fixes
• Off track can also look like a track bent away from the wall with the roller pinched inside it, or a panel twisted because one side dropped while the other held. Source: Garage door off track: causes and fixes
• A snapped lift cable: the door hangs crooked, one side lower than the other, and the cable left is carrying a load it was not sized for. Source: What counts as a garage door emergency

Is it safe to use the door right now?

No. Unplug the opener and stay clear.

• Unplug the opener so the door gets no further cycle, and keep away from the springs and cables. Source: Garage door off track: causes and fixes
• If the door is open and resting on its rollers in the horizontal track, don’t try to lower it by hand. Source: Garage door off track: causes and fixes
• With a snapped cable, don’t level the door by hand, don’t reach between the panels to look, and don’t cycle the opener. Source: What counts as a garage door emergency

DIY or a pro, and why

A technician: the springs and cables are still under tension.

• A fully wound torsion spring holds about 236 foot-pounds, enough to break a wrist. When panels twist, cables can come off their drums and that tension goes wherever it can. Source: Garage door off track: causes and fixes
• Rewinding a cable that came off its drum, loosening a drum set screw or moving a drum on the shaft all need the spring unwound first: technician work. Source: How the cable drum works
• What you can check, with the door closed and the opener disengaged: cracks in each drum, fraying or rust where the cable leaves the groove, and whether the cable sits in the groove. Source: How the cable drum works

What the fix involves and costs

• The track is rarely the whole story. The usual causes are brackets loosened by vibration, a weak or broken spring, an impact, cold, and grease in the tracks. Source: Garage door off track: causes and fixes
• Don’t grease the tracks. Rollers are made to roll, not slide; grease makes them skid at the transitions and get pushed sideways out of the channel. Source: Garage door off track: causes and fixes
• Why cables snap: if a drum slips on the shaft, the door drops on one side and the cable on the other side, suddenly carrying the full weight, can break. Source: How the cable drum works
• Resetting an off-track door runs $150 to $350, more if cables or rollers also failed. Source: Garage door repair cost in 2026
• A $200 spring job can grow into a $600 repair once an out-of-balance door has worn down the rest of the assembly. Source: Garage door off track: causes and fixes
