Our Repair techs have substantial levels of experience. We constantly have the parts you need offered on every truck so we will not need to bother you a 2nd time to obtain your Garage Door running right. Garage Doors weigh hundreds of pounds. The complete weight of the Door is carried 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 prior to it deteriorates and overburdens the Garage Door Opener, eventually triggering it to break or fail. The Opener is not created 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 fully closed position pull down on the red detach cable. Then try lifting the Door. If the Door is very heavy and drops of its own weight when you release the Door Springs and hardware are worn and are not doing their job, putting unnecessary strain on the Opener.
