What You Are Seeing
If your opener hums but the door doesn't move, that's usually the drive gear - a nylon part that wears down over years of use and finally strips its teeth. Houses in this area built around 1982 are hitting the age where that part has had three or four decades of cycles on it, which is about the outer edge of its life even on a unit that's been maintained.
If the opener does nothing at all - no light, no hum, no click from the wall button - look at the logic board first. Boards fail from age, from a power surge, or from moisture getting into the housing over enough winters. Colorado's cold-and-severe climate band means bigger temperature swings on anything mounted in an unheated garage, and that stress adds up over the life of a board built decades ago.
A door that reverses right after it touches the floor, or won't close at all, points to the safety sensors - either misaligned or wired into a board that's no longer reading them right. That one's often simpler to fix than it looks, but we won't know until we're standing in front of it.
Parts We Carry
We stock the drive gears, wall buttons, safety sensor pairs, and logic boards that fit the openers most common on homes from the early 1980s and later - chain and belt drives, half-horsepower and three-quarter-horsepower units. Those cover the bulk of what we see on this side of the service area.
What we won't pretend to carry is every board for every opener ever sold. If your unit is the original one from when the house went up, and the manufacturer's since discontinued that model line, we may need to order the part rather than pull it off the truck. We'd rather say that up front than quote you a same-visit fix we can't deliver.
In a fair number of those cases, once we've priced the discontinued board against a new opener, replacement comes out ahead - newer units run quieter, handle the cold better, and don't leave you waiting on a part that's getting harder to find every year. We'll lay out both numbers and let you decide; we're not pushing a sale either direction.
