Garage Door Stuck Halfway: Causes & Repair Costs

The classic halfway jam on double doors: one torsion spring snaps mid-lift with a bang, the opener drags the door a few inches against the imbalance, then gives up. A visible gap in the coil above the door is the confirmation. The two springs share an age and cycle count, so when one fails the other is close behind — the durable fix replaces the pair and re-balances the door.

Rollers jump the rail at a weak spot — a slight bend, a loose bracket, a roller worn to a flat edge — and the door binds crooked: one side keeps travelling while the other hangs. Cycling it again only wedges it tighter and bends the track further. Realignment re-seats the rollers, re-plumbs the track and cycle-tests the door; the rollers that derailed are usually replaced at the same time.

A lift cable frays quietly for years, then lets go — usually right at the drum. One side drops, the door twists in its opening, and the twisted tracks become the jam points. Cables and springs age on the same cycle, so a cable that snaps at ten years says something about the springs too: the durable fix replaces the pair and inspects the drums.

The door stops at exactly the same height every cycle — that's a bend, not a random jam. An Etobicoke two-car garage last winter: a basketball backboard shifted in storage, leaned into the track overnight, and the door jammed at chest height on the school run. Light bends straighten on-site with the door secured; creased sections get replaced. The tell: a visible kink or fresh scrape marks where the rollers pass.

The door starts, travels a foot or two, then the opener gives up with a click — the force sensor doing its job. It trips when the door feels heavier than expected: an out-of-balance door, a spring failing without having snapped yet, or limits left too low after an earlier repair. The fix is a balance check plus a force-adjustment visit; motor circuit faults are quoted on-site.

Toronto's winter angle: meltwater runs into the lower track, freezes overnight, and the expansion wedges the rollers solid by morning. Clearing and lubricating the track is the honest fix — what matters is checking for the bend the ice left behind, because expanding ice bends light-gauge track exactly like an impact does.
