Why It Happens Here
Most of the houses we work on in Cheyenne went up between 1989 and 1992, and that matters more than people think. Openers from that era used nylon drive gears and lighter-duty circuit boards, and thirty-plus years later those gears strip and those boards corrode at the solder joints. That's the median build year across the service area, and it's why we see the same opener generation fail in Fox Farm-College, South Greeley, and out toward the Ranchettes.
The other piece is the climate. Cheyenne sits in a cold-severe band, and an unheated garage here routinely drops well below where grease and plastic gears want to operate. Cold grease thickens, the motor has to work harder to turn the gear train, and that's the load that finally snaps a nylon tooth or burns out a capacitor that was already marginal. We don't get the humidity failures some regions do - we get cold-soak failures, plain and simple.
A belt or chain opener installed in 1990 was never built to run efficiently at 10 degrees for months at a stretch. Add three decades of that cycle and the gear, the logic board, or the safety sensor wiring is usually what gives out first, not the door itself.
