All-O-Matic Gate Operator Repair in Dallas–Fort Worth
All-O-Matic operators are workhorses — simple, heavily built, and very repairable. They also turn up on a lot of older Dallas properties where the original installer is long gone. We service them, stock the common parts, and have the repair photos and video to show for it.

Why All-O-Matic operators get replaced when they should be repaired
All-O-Matic units are mechanically straightforward, which means the failure is almost never the whole operator. It is a limit switch, a clutch adjustment, a chain, or a control board. Anyone quoting you a full replacement on an All-O-Matic has not opened it.
What usually goes wrong
- Limit switch cam slip and travel drift
- Clutch out of adjustment causing stalls under load
- Chain stretch and sprocket wear
- Control board relay failure
- Motor brush wear on older SL and SW units
- Gearbox oil loss

All-O-Matic repair questions
Are All-O-Matic parts still available?
Yes. All-O-Matic is still in production and the common wear parts — limit switches, clutches, chains, boards — are readily available. This is one of the more economical operators to keep running.
My All-O-Matic stalls partway and reverses. What is it?
Usually the clutch or the limit cams. The clutch is a safety feature — it slips when the gate meets resistance, so if the gate is binding on its track the clutch is doing its job and the real fault is alignment. We check the gate by hand before touching the operator.
How old is too old for an All-O-Matic?
These units routinely run twenty years or more with basic servicing. Age alone is not a reason to replace one. We look at gearbox condition and parts availability, not the date on the label.
