- The call
- After the power came back you pulled the red cord to get the car out. Since reconnecting, the door stops short of the floor, and no amount of turning the limit adjustment brings it the rest of the way down.

There is a new squeal from the front of the rail, up near the header, on every cycle. The belt has started tracking to one side and its edge is fuzzy where it has been rubbing.
The most common belt-drive repair is the simplest: the belt has stretched over thousands of cycles and hangs slack under the rail. On its way up it slaps the rail and skips a tooth or two on the sprocket. Tension lives at the trolley, where a threaded shaft, a spring and a square nut set how much the belt is pulled taut. The technician sets that spring to the maker's stated length, confirms a little give at mid-span, then runs the door and listens. If the belt has stretched past what the adjuster allows, or the rubber has aged, a new belt goes in instead.

Scene 1
With the trolley run to one end of the rail and then the other, the whole length of the belt passes under the technician's eye and fingers, on the top run and the return. What they are looking for is specific: cracks across the back of the rubber, a glazed shine that says the belt has been slipping, an edge gone fuzzy from rubbing, a stretch where the teeth are flattened or torn away, cords showing through, and the state of the clip or link where the belt meets the trolley. Each of these points to a different cause as well as a different repair, and where the wear sits along the belt says a lot about which.
Scene 2
When the shavings on the housing say the drive gear has stripped, the head unit's cover comes off and the gear-and-sprocket kit is replaced as a set. The belt is lifted off the sprocket, the old sprocket shaft and worm gear are withdrawn from the housing, the new gear is greased with the light grease the maker names and fitted with its bushings, and the sprocket is set back on top. The technician checks the motor shaft's end play, since too much play is often why the gear stripped in the first place. The belt is refitted, tensioned and phased, and the operator is run to confirm the sprocket turns true and quiet.
Scene 3
You now know where the release handle hangs and what happens when you use it. A pull parts the trolley so the door can be lifted by hand through a power cut; running the motor, or a second pull, reconnects it. What matters after this repair is to pull it only with the door closed. Releasing a door that is open, or one whose springs are tired, can let it fall because the spring no longer carries its weight; the release itself disconnects the trolley from the belt, so the falling door lands on its tracks and hinges, not the belt the technician just corrected. Practise it once with the door down so the first real use is calm.

When the belt has been off the sprocket, or the motor has run without it, the motor's idea of where the door is no longer matches where the trolley sits. The door then stops short at one end however the limits are turned. The technician lifts the belt off, runs the sprocket to its closed position, refits the belt with the trolley at the closed end and relearns the limits.
No. The belt is meant to run clean and dry; oils and sprays soften the rubber and gather grit in the teeth, which wears the sprocket. Lubricant belongs on the door instead: hinges, rollers and springs get a garage-door lubricant once a year. The gear inside the motor head takes a light grease when it is serviced, and that is the technician's job.
A belt's life is counted in cycles and years, and on a balanced door with the rail straight and the tension right it runs for many years. What shortens it is a heavy door, an over-tight adjustment, a bent rail rubbing one edge, or grease on the rubber. Keep the door balanced and lubricated, the belt dry, and glance along the rail a few times a year.
