All-O-Matic Slide Gate Operator Repair Houston TX
Rampart services All-O-Matic slide operators, including the SL45, SL90, and SL100FP commercial models, testing motor, limits, and chain condition. Commercial All-O-Matic units see high-cycle use, so chain and sprocket wear is checked before assuming a motor fault.
All-O-Matic operators are common on Houston apartment, storage, and warehouse slide gates. When the gate runs and stops, won't close, or grinds under load, we diagnose the drive train and board β and check the gate itself before condemning the operator.
All-O-Matic Problems We Fix
Slide operator faults, residential and commercial.
- Gate runs then stops mid-travel
- Won't close or over-travels
- Worn clutch slipping under load
- Chain or sprocket worn / jumping
- Control board or limit fault
- Motor straining or overheating
Houston Conditions That Stress All-O-Matic Operators

High-Cycle Commercial Wear
Apartment and storage gates on All-O-Matic operators cycle far more than residential β wearing the clutch, chain, and sprocket faster than rated. Most All-O-Matic calls are mechanical wear, not electrical failure.
Clutch Slip Under Load
The All-O-Matic's mechanical clutch slips when it wears or when a dragging gate forces it past its setting. The motor runs but the gate barely moves. We adjust or replace the clutch and fix the underlying drag.
Board & Limit Faults
Heat and surge damage the control board, and vibration from high-cycle use drifts the limit settings. We test the board and recalibrate limits after confirming the drive train is sound.
Why Does My All-O-Matic Gate Run Then Stop?
An All-O-Matic that starts and stops is usually a limit-switch setting, a worn clutch, or a chain or sprocket binding under load. On high-cycle commercial gates these wear predictably. We adjust limits and inspect the drive train before replacing the control board.
A start-then-stop fault on a commercial slide gate is most often mechanical resistance the operator can't overcome β a binding chain, a slipping clutch, or a gate dragging on its track. Replacing the board without fixing the resistance just sends the new board down the same path.
- Clutch inspected and adjusted or replaced
- Chain tension and sprocket wear checked
- Limit settings recalibrated
- Track and rollers checked for the drag forcing the stop

All-O-Matic Commercial Slide Gate Repair in Houston β What We Service
All-O-Matic SL-45, SL-90, and SL-100FP slide gate operators are workhorses found at Houston storage facilities, apartment complexes, and commercial properties. We carry parts for all three models and service their motors, control boards, chains, clutches, and limit switches. As a BBB Accredited business, we provide the documentation commercial properties need for service records.
The most common All-O-Matic failure on high-cycle commercial installations: chain wear and clutch slip. An operator cycling 200+ times a day wears its chain far faster than a residential gate. We catch this during maintenance visits before it causes a complete failure β which is why gate maintenance contracts pay for themselves on commercial properties.
Many All-O-Matic installs also have Knox 911 emergency access hardware. We service the Knox box alongside the operator so fire code compliance stays current.

All-O-Matic Slide Gate Operator Repair Houston TX β Frequently Asked Questions
What All-O-Matic models do you repair?
We service the common All-O-Matic slide operators β SL-45, SL-90, and SL-100FP β plus their swing models, including motors, control boards, limit assemblies, chains, and clutch adjustments, on residential and commercial Houston gates.
Why does my All-O-Matic gate run then stop?
An All-O-Matic that starts and stops is usually a limit-switch setting, a worn clutch, or a chain or sprocket binding under load. On high-cycle commercial gates these wear predictably. We adjust limits and inspect the drive train before replacing the board.
Do you provide priority service for commercial All-O-Matic gates?
Yes. All-O-Matic operators are common on Houston commercial properties, and stuck commercial gates get priority dispatch; same-day service may be available. We carry common commercial parts when available. Call (713) 816-5880.
What does All-O-Matic repair cost in Houston?
Gate opener and electronic troubleshooting requires a diagnostic service call. See our Gate Opener Repair page for current diagnostic pricing. Structural repair and new-install estimates are available at no charge, and we provide a written quote before work begins.
Do you service All-O-Matic SL-45, SL-90, and SL-100 differently?
The diagnostic approach is the same across all three β motor, board, chain, clutch, and limits β but the SL-100FP has a full-feature control board with more diagnostic outputs. Parts differ between models, and we confirm model compatibility before ordering. We service all three on-site across Houston commercial properties.
