Our Repair techs have substantial levels of experience. We constantly have the parts you require available on every truck so we will not need to trouble you a 2nd 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 a beneficial life span of about 5-10 years before it deteriorates and overburdens the Garage Door Opener, ultimately triggering it to break or fail. The Opener is not developed to do any heavy lifting, that is the task of the Door hardware. A simple test to see if your Garage Door hardware is doing its task is this: With the Door in the fully closed position pull down on the red disconnect cord. 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 used and are not doing their job, putting excessive stress on the Opener.
