Our Repair techs have comprehensive levels of experience. We always have the parts you need readily available on every truck so we will not need to bother you a second time to get your Garage Door running right. Garage Doors weigh numerous pounds. The complete weight of the Door is brought by the Garage Door hardware, such as the Springs, Cables, Rollers, Bearings, etc. This hardware has an useful life expectancy of about 5-10 years before it damages and overburdens the Garage Door Opener, eventually triggering it to break or stop working. The Opener is not designed to do any heavy lifting, that is the job of the Door hardware. A simple test to see if your Garage Door hardware is doing its job is this: With the Door in the fully closed position take down on the red disconnect cord. Then try lifting the Door. If the Door is extremely heavy and drops of its own weight when you let go the Door Springs and hardware are worn and are refraining from doing their job, putting undue stress on the Opener.
