Our Repair techs have comprehensive levels of experience. We always have the parts you need available on every truck so we will not have to bother you a second time to get your Garage Door running right. Garage Doors weigh hundreds of pounds. The complete weight of the Door is brought by the Garage Door hardware, such as the Springs, Cables, Rollers, Bearings, and so on. This hardware has a beneficial life span of about 5-10 years prior to it weakens and overburdens the Garage Door Opener, eventually triggering it to break or stop working. The Opener is not developed to do any heavy lifting, that is the job of the Door hardware. An easy test to see if your Garage Door hardware is doing its job is this: With the Door in the completely closed position pull down on the red disconnect cable. Then attempt raising the Door. If the Door is really heavy and drops of its own weight when you let go the Door Springs and hardware are worn and are not doing their task, putting undue stress on the Opener.
