On the wider double doors common in Ashland, the most frequent emergency call is a broken torsion spring - usually both springs failing close together since they're matched and wear at the same rate. You'll hear a loud bang, and the door won't lift, or it lifts a few inches and stops.
Second most common: opener sensor faults. Post-2000 openers run photo-eye safety sensors low on the track, and a knocked-out-of-alignment sensor reads as the door refusing to close, reversing partway, or blinking a light with no clear cause. That's often a five-minute fix once we're on-site, not a parts problem.
Third: track binding tied to foundation settling, as above - a door that used to run smooth now catches at the same spot every time, usually near the bottom of a double door's wider span.
What we don't see much of here, compared to older stock elsewhere in the area, is rust-through on panels or brittle, decades-old extension springs. Ashland's newer builds mostly dodge that particular failure.
