In houses from the early-90s Gilbert boom, the failure pattern is pretty consistent. The door works fine for months, then one morning it's heavier than it should be, or it slams the last six inches instead of settling. That's a spring losing tension, not an opener problem, even though the opener usually gets blamed first because it's the thing making noise. In the four established pockets of 1980s-90s construction across this service area, we also see steel panels that have taken enough summer expansion and contraction that the rollers wear oval instead of round, so the door starts binding in the track at the same two spots every time. Cables fray near the drum after years of that same heat-driven flex. None of this shows up as a sudden break most of the time - it shows up as a door that's slightly worse than it was last month, until one day it isn't slightly anything, it's stuck.
