The most common call from this part of town is a broken torsion spring on a door that's never been serviced - the owner hears the bang, the door won't lift, and the opener just strains against dead weight. Close behind that is a worn-out extension spring setup on an older single door, where the safety cable (if one was ever added) is the only thing keeping a snapped spring from becoming a projectile. Openers from this era, especially chain-drive units installed when the house was newer, tend to fail at the drive gear or the circuit board rather than the motor itself, and by now most of them are well past any parts warranty. Rollers seizing in the track is another frequent one, especially on the north-facing side of a garage where moisture lingers longer through a cold winter. Less common, but it happens: a bent track from someone backing into the door, which looks like a spring problem until we get eyes on it. We won't guess over the phone which of these it is - a torsion spring failure and a track misalignment sound almost the same from inside the house, and the fix is nothing alike.
