If your door won't lift, or it lifts a few inches and stalls, that's almost always a broken torsion spring, not the opener. The opener motor isn't built to carry the door's full weight once the spring snaps, so it strains, groans, and sometimes trips its own breaker trying. On the newer builds common around Milford, you're more likely to find a single wound spring sized for lighter, 1970s-era panel doors than the dual-spring setups on older, heavier wood doors elsewhere in the service area. A loud bang from the garage, usually when no one's home, is the spring letting go. If the door looks crooked when it's halfway up, one spring is still holding and the other isn't - don't force it the rest of the way.
