The calls we get from Catlettsburg tend to describe one of a few things: the opener motor runs but the door doesn't budge, the unit clicks or hums without moving at all, the remote works from close range but not from the driveway, or the light on the unit blinks a code and nothing happens when you press the button.
A door that reverses right after touching the floor, or won't close all the way, usually points to the safety sensor pair rather than the motor - worth checking before assuming the whole opener has failed. If the motor runs continuously and never disengages the drive, that's a limit switch or logic board issue, not a mechanical one, and it's not something to keep testing by hand.
