Our Repair techs have extensive levels of experience. We always have the parts you require available on every truck so we will not have to trouble you a second time to obtain your Garage Door running right. Garage Doors weigh numerous 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 before 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 task of the Door hardware. An easy test to see if your Garage Door hardware is doing its task is this: With the Door in the completely closed position take down on the red detach 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 task, putting unnecessary strain on the Opener.
