The call we get most from this stretch is the door that hesitates - it starts to open, stutters, and either stalls or finishes the cycle on the second try. Nine times out of ten that's a chain-drive opener from the original build era finally losing enough gear strength that it can't clear the first push, especially once winter cold has thickened the old grease. The other version is a door that reverses partway down for no clear reason, which usually traces back to a photo-eye sensor that was never part of the original install and got added later, sometimes wired loosely. Either symptom is worth a look before the opener fails outright and leaves the door stuck in whatever position it happened to be in. Full replacement isn't always the answer - sometimes a worn one is just tired, and sometimes it's the motor. We tell you which after we've actually opened it up, not before.
