Our Repair techs have extensive levels of experience. We constantly have the parts you need offered on every truck so we will not have to trouble you a second time to obtain your Garage Door running right. Garage Doors weigh hundreds of pounds. The full 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 span of about 5-10 years prior to it damages and overburdens the Garage Door Opener, ultimately causing it to break or stop working. The Opener is not created 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 completely closed position take down on the red detach cord. Then try raising the Door. If the Door is really heavy and drops of its own weight when you release the Door Springs and hardware are worn and are not doing their task, putting excessive pressure on the Opener.
