Off-track garage door repair

When a door won't close, the cause is either the safety system or the hardware, and it helps to know which. If the door closes only while you hold the wall button down, the photo eyes are stopping it, which is an opener-side fix. If it stops or reverses at the same spot every time, it's usually binding: a bent track section, a roller dragging, a hinge catching, or a door that's out of balance, so the opener's force limit trips and the door backs up.

Other mechanical causes are easy to miss. A manual lock bar left half engaged will stop a door cold, which is why DASMA tells installers to remove or disable manual locks when an opener goes on. A door that isn't level won't seal or reverse properly; DASMA's opener installation guidance says the door must be level to the floor, because gaps keep the reversal systems from working across the full width. A vertical track that's out of plumb or set at the wrong distance from the jamb can bind the rollers too.

Noise and shaking usually come from the parts that carry the door along the track: rollers, hinges, the track and the fasteners that hold them. Worn rollers rattle and bounce instead of rolling. Hinges loosen and crack. Track bolts and lag screws back out of the jamb after years of vibration. A door that's out of balance adds a lurch at the start and a slam at the end, and the opener feels every bit of it.

DASMA's homeowner damage checklist is a good map of what we look at: track fasteners and alignment, rollers that should turn and slide freely in their brackets, roller brackets and hinges that should be tight, and the spring system. DASMA also notes that springs can squeak from normal use and that a spray lubricant made for garage doors may quiet them. Grinding, popping or shaking that keeps getting worse is different; that's a part wearing out.

We straighten what can be trusted and replace what can't. Lightly bent track can sometimes be trued, but creased or kinked track gets replaced, because rollers keep catching on a damaged spot. Vertical tracks get reset plumb at the right distance from the door, loose jamb brackets get re-anchored into solid framing, and the horizontal tracks get hung solidly. DASMA's guidance is that horizontal track that sags or twists with the door open should be stiffened with angle braces or back hangs.

Rollers and hinges are wear parts. Haas Door offers black or white nylon rollers and 10-ball steel rollers on its residential doors, and we can talk through which suits your door. Struts matter too: DASMA defines a strut as the stiffener that reduces deflection of the door sections when the door is open, and it also adds wind-load capacity, so a bent or missing strut is part of the repair. If a cable failed and caused the derailment, it gets fixed at the same visit, since a door can't run straight with one side slack.

Delaware gets winter and spring nor'easters, autumn tropical systems and spring and summer thunderstorms, according to the state climate office at the University of Delaware, and wind is hard on track. DASMA explains that wind pushing on a closed door can drive the top rollers up the curve of the track and lift the door open, which is why it recommends closing the door, and locking it if it has a manual lock, before high winds arrive.

After a storm, look before you run the door. DASMA's checklist for building occupants says to inspect alignment, track fasteners, rollers, hinges and the spring system with the door closed, and to stop and call a trained technician if anything is bent, loose or out of place. IBHS notes that wind-rated doors depend on specific components, including track, jamb brackets, hinges, rollers and reinforcing struts, so storm-damaged hardware on a rated door should be replaced with the parts its rating calls for.
