LiftMaster is the most common opener brand along the Front Range, and the one most often fitted by builders through the region's growth years.
Walk any street in Briargate, Falcon or Monument put up since the late nineties and you will find LiftMaster units, or their retail-badged Chamberlain siblings, in most of the garages. That is good news for you when something goes wrong: these are serviceable machines with a deep parts supply, and repair is nearly always the sensible route.
If the motor sounds completely normal but the door does not budge, you are almost certainly looking at a chewed-out nylon drive gear inside the head unit. It is the most common LiftMaster fault there is, and it is worth being able to spot because of the price difference: a gear and sprocket kit plus an hour of labour, versus several hundred dollars for a replacement opener you do not need. If someone quotes a new unit for that symptom without taking the cover off, get another quote.
The rest of the list, in rough order of frequency: capacitors on units past their first decade, logic boards taken out by surges, not a rare event given how often Front Range storms interrupt power, drifted travel and force settings, and photo-eyes that have wandered out of alignment.
Worth knowing specifically: a LiftMaster that starts reversing partway up in December is usually not failing. Its force limit is correctly refusing to fight a door that has become heavier. Stiff grease, a bottom seal frozen to the slab, slightly contracted springs. The wrong response is to turn the force setting up, which defeats a safety feature and burns out the motor. The right response is to fix the door. We hand-test balance before touching any force adjustment.
Almost certainly the plastic drive gear inside the motor unit. The motor is fine and no longer connected to the drive. A gear kit plus about an hour fixes it, far cheaper than a new opener.
Usually not. The force limit is correctly refusing to fight a door that has got heavier from stiff grease, a frozen seal or contracted springs. Turning the force up defeats a safety feature and burns the motor. Fix the door instead.
Usually yes. Parts availability is good and the designs are serviceable. We would only push replacement if it lacks photo-eye sensors, or needs both board and motor work.
