Put off lubricating your garage door one more season and here's what usually happens: the rollers start grinding against dry metal, the opener motor works harder to compensate for friction it was never designed to fight, and by the time cooler nights roll around in December, you're looking at a seized hinge or a strained opener gear instead of a five-minute maintenance job. A bottle of garage door lubricant costs a fraction of what a service call for a burnt-out opener motor runs. Fall is the window to get ahead of it, before the next stretch of heat bakes whatever lubricant is left in your hardware down to nothing.
