The complaint we hear most from Trinity is a door that worked fine all summer and then started groaning, catching, or refusing to close all the way once the weather turned. North Alabama sits in a cold-moderate climate band, and the freeze-thaw swing through winter is exactly what finishes off a spring that's already fatigued from thirty-plus years of cycling. Metal contracts, tension shifts a hair, and a spring that was one winter from failing finally gives. On older openers, the same cold snap often exposes a drive gear that's been slowly stripping - the door moves but the opener motor just hums. Neither problem announces itself months in advance. It's usually fine, fine, fine, then stuck.
