Most houses in Auburn went up around 1992, which puts the original garage door hardware squarely in the early-90s run: steel sectional doors, chain-drive openers with the orange safety-reverse sticker still half-peeled off, and torsion springs sized for the thinner doors builders used back then. Thirty-plus years on, that's the hardware failing now. Springs wound in the early 90s are past their cycle count no matter how well the door looks. Openers from that era often lack working photo-eye safety sensors or have ones that have drifted out of alignment over the decades, which is one of the most common reasons a door won't close all the way. If your house is one of the newer builds mixed in around Auburn, the fault is usually different - worn rollers or a opener logic board, not the spring itself. Either way, the fix depends on knowing which decade's hardware you're dealing with before a truck ever gets loaded.
