Identify what your door is doing before you call. If it is one of these, do not keep operating it.
Your torsion spring has snapped under intense torsional load. Forcing the opener to lift the door without spring assistance will burn out the motor or snap the drive belt.
A stripped internal nylon drive gear or a blown starting capacitor. We carry complete carriage gear rebuild kits in our trucks to repair your system immediately.
Don't let a snapped spring, snapped cable, ripped weather seal, or a defective remote keep you locked inside. Our expert teams carry fully stocked dispatch trucks. We regularly perform comprehensive garage door maintenance (inspection, lubrication, adjustment, and component testing) to keep your system safe. We serve Thornton and the cities around it.
The dent is the cheap part. A bumper into the bottom section, or a door closed onto something solid, moves the corner hardware with it. The bracket down there is what the lift cable pulls against; bend it and the cable slackens, jumps the drum, and the door comes up crooked or stalls. Shove a section an inch out of plane and the rollers above it stop running true, and a straight hit ends up as a flattened track curve. So track and cable come before the panel. Whether that panel can be bought on its own comes down to whether its maker still builds that door, which is a question about the model rather than the year — and the year is all the census will give up: a median build year of 1966 for Thornton, carrying a margin of 17 years, with 179 of its 285 homes finished before 1980. So the sticker that would name the model gets looked for, and where it will not read, the door gets measured instead. Either way the door gets run by hand off the opener first, because a hit that looks cosmetic can leave the counterbalance pulling against bent steel.
