Special-order gear kits
A stripped gear means opening the drive housing, and the gear kits for some of these older chain-drive units are not something you'll find at a hardware store - they're a special order, and we won't pretend otherwise.
Bartlett, TN
Opener trouble in a Bartlett home built between 1972 and 2005 has a pattern. We know the gears, boards, and chains that fail here and how to fix them right.


Local causes
Most of the housing stock across this service area went up between 1972 and 2005, with a lot of it clustered in the 1980s and 90s across the ten or so named communities we work in. That matters for openers because a huge share of those original units are still in garages today, either the factory unit or a straight swap-in replacement from a decade or two back. Chain-drive openers from that era use steel gears on the drive assembly that were never built to run forever, and after enough winters they strip quietly, a tooth or two at a time, until the carriage stops moving even though the motor still hums.\n\nThe cold-moderate climate here adds its own wear pattern. Grease in the drive gear and on the rail thickens up on the hard-freeze mornings we get a handful of times each winter, which puts extra load on a motor and circuit board that are already twenty-plus years old in a lot of these houses. That combination - older openers, older lubricant doing its job less well in the cold - is why opener calls cluster the way they do across this area instead of being random.
Warning signs
The most common call is a door that reverses before it closes, or won't close at all. On units installed when these neighborhoods were first built out, that's usually the safety sensor alignment or wiring, since those sensors sit low near the track where moisture and temperature swings do the most damage over 20-plus years. A close second is the opener that runs but the door doesn't move - often a stripped gear on a chain-drive unit, which is mechanical and doesn't get better on its own.\n\nWe also see a fair number of circuit board failures, especially on openers that were already mid-life when newer logic boards became standard. A board that's failing intermittently can look like a dozen other problems: remote not working, wall button dead, door moving a few inches and stopping. And on the newer end of the housing stock, built closer to 2005, we get calls about Wi-Fi-connected openers losing their pairing or the app going dark, which is a different fix entirely from a gear or a sensor.
DIY or pro
Sensor alignment is worth trying yourself before you call anyone. Both sensors need to sit at the same height and point straight at each other - a bumped car or a weed trimmer knocks them off more than people expect, and realigning them takes five minutes with no tools.\n\nPast that, we'd tell you to stop.

If you force a jammed carriage or try to bypass a dead sensor by disconnecting the safety circuit, you turn a repair into a door that can come down on a car or a kid.
Circuit board diagnosis also isn't a guess-and-check job; a board that's borderline can run fine for a week and then fail completely, and chasing the wrong symptom wastes your money and ours.\n\nIf your opener is original to a house built in the 1980s or 90s, there's a real chance that replacing it costs about the same as repairing it once you add up a gear kit, a board, and labor. That's a conversation worth having before we start, not after.
Booking
We work opener calls across Bartlett and the surrounding service area - Lakeland, Millington, Arlington, Germantown, Atoka, Gallaway, Munford, Oakland, Piperton, and Brighton, along with the closer-in areas like Daybreak, Wolfchase, Cordova, and Raleigh. Tell us the opener's rough age and brand if you know it, and whether the door moves at all, reverses, or does nothing - that alone usually tells us what's on the truck before we show up.\n\nHead to our home page to get in touch and get a call scheduled.
Questions
On older chain and screw-drive units that's almost always a stripped internal gear - the motor spins but nothing transfers to the carriage. It's a mechanical part failure, not something that fixes itself, and it's common on openers that have been running since these neighborhoods were first built.
Cold thickens the grease on the drive gear and rail, which adds strain to a motor and board that may already be two decades old. That extra load is often what finally pushes a marginal opener into failing completely during a cold snap.
If the unit is original to a house built in the 1980s or 90s and the problem is a stripped gear or a failing board, replacement often costs about the same once parts and labor are added up. We'll tell you honestly which way the numbers point before we start work.
Often, yes. Check that both sensors sit at the same height and point directly at each other - a bump from a car or trimmer is a common cause. If they're aligned and it still won't close, the wiring or the sensor itself likely needs a look.
