Automatic Gate Motor Replacement & Upgrades

Industrial-Grade Power Solutions and Diagnostic Testing in DFW.

The electric motor is the undisputed workhorse of your access control system. Day in and day out, it is tasked with pulling or pushing hundreds, sometimes thousands of pounds of heavy steel. When a gate motor finally reaches the end of its lifespan, your property is left vulnerable. At A.S. Gate & Fence, we specialize in heavy-duty gate motor replacements, comprehensive electrical diagnostics, and high-cycle upgrades for residential and commercial properties across the Dallas-Fort Worth metroplex.

The Anatomy of Motor Failure: Wear, Tear & Heat

Gate motors do not just stop working overnight. They succumb to a compounding cycle of mechanical and electrical stress.

Mechanical & Electrical Degradation

Years of pulling heavy loads inevitably strip internal gearboxes, wear down motor brushes, and degrade the copper stators. As the internal moving parts suffer from friction and moisture intrusion, the electrical components must work twice as hard to move the gate, creating a dangerous power draw.

The Thermal Overload Threat

If a motor is fighting against a dragging gate, a rusted hinge, or a derailed track, it will pull extreme amperage and overheat. This thermal overload melts internal wiring insulation and can send a massive voltage spike directly into your expensive main control board, destroying the entire system.

Expert Labor: We Test Before We Install

The biggest mistake amateur technicians make is bolting a brand-new motor onto a mechanically compromised gate. If the gate itself is causing the resistance, the new motor will burn out in a matter of months.

  • Mechanical Load Testing: We disengage the operator and manually test the gate's physics. We locate and fix the dragging track, seized roller, or leaning post that killed your original motor before installing the new one.
  • Electrical Overload Diagnostics: We utilize advanced multimeters to trace the electrical load, ensuring the new motor receives clean voltage without risking damage to your motherboard, transformer, or safety sensors.
  • Precision Calibration: We expertly calibrate your new motor's open/close limits, force sensitivity, and dip-switch settings for flawless, safe operation.

Uncompromising Materials: OEM Gate Motors

We replace failing units with 100% genuine OEM (Original Equipment Manufacturer) motors directly from industry leaders like Liftmaster, Elite, All-O-Matic, Viking, and US-Automatic. We calculate your gate's exact weight and daily cycle volume to match you with a heavy-duty motor block engineered with advanced thermal protection, ensuring it survives the brutal Dallas-Fort Worth summers without overheating.

Protect Your New Motor: The $95 Annual Maintenance Service

A new motor is a significant investment. Protect it with our comprehensive $95 Annual Maintenance Service. We prevent premature wear and tear by lubricating all moving gears, adjusting the drive chain tension, clearing debris from the chassis, and verifying the electrical draw stays within safe limits year-round.

Is Your Gate Motor Smoking, Grinding, or Dead?
