The full weight of the Door is carried by the Garage Door hardware, such as the Springs, Cables, Rollers, Bearings, etc. This hardware has a helpful life span 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 designed 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 job is this: With the Door in the totally closed position pull 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 job, putting unnecessary stress on the Opener.
