Put off replacing a tired opener for one more season and here's what you're actually risking: a chain that finally snaps during a January cold snap, a motor that strains and burns out trying to lift a door stiffened by freezing temperatures, or a unit that just quits the morning you need to get to work during a nor'easter. An opener that's already straining in October rarely makes it gracefully through a Connecticut winter. If yours is grinding, hesitating, or reversing for no reason, now is the window to deal with it before the weather turns.
