An opener does less heavy lifting than people think. The springs carry the weight of the door, and the opener mainly guides it up and down along a rail using a trolley driven by a chain or a belt. Inside the motor head are a logic board, a motor, and a set of gears, and at the base of the door are two photo eye safety sensors that stop and reverse the door if anything crosses their beam. Modern units from LiftMaster and Genie add Wi-Fi, battery backup, and smartphone control through apps like myQ.
Openers fail for a handful of common reasons. A plastic drive gear can wear out and strip, so the motor runs but the door does not move. The safety sensors can fall out of alignment or get dusty, which makes the door reverse before it closes. Remotes and keypads lose programming or batteries, logic boards can be damaged by power surges, and the Central Valley heat and dust are hard on the electronics over time. Because an opener also depends on a balanced door, a unit that strains is sometimes fighting a spring or roller problem rather than failing on its own, which is why we test the whole system.
