Our Repair techs have comprehensive levels of experience.

The full weight of the Door is carried by the Garage Door hardware, such as the Springs, Cables, Rollers, Bearings, and so on. This hardware has a beneficial life expectancy of about 5-10 years prior to it compromises and overburdens the Garage Door Opener, eventually triggering it to break or stop working. The Opener is not designed 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 take down on the red disconnect cable. Then try lifting 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.
