Broken Gear and Sprocket
Garages doors can weigh up to 400 lbs. For them to open, a number of parts need to work together with one another. Like any other mechanical system, parts will eventually break or wear out over time. The gear and sprocket are the most common parts that break and need to be replaced. They connect the motor to the chain or belt.
The springs on the garage door will eventually weaken, putting stress on the bushing. As the bushing wears down on top of the unit, the teeth of the gear will slowly grind down. Once the teeth have become fully worn, the gear that powers the belt or chain can no longer turn. The end result is a motor that runs, but a stuck garage door.
