FAAC Gate Motor Replacement Nationwide

FAAC Gate Motor Replacement: The Fort Worth Owner’s Guide

FAAC gate motor replacement in Fort Worth typically runs $1,450 to $2,900 installed, depending on your model series and whether we’re swapping just the motor or rebuilding the actuator assembly. We stock FAAC-compatible motors and parts on our trucks and can usually complete the swap in one visit, same day for most residential swing and slide gate systems. Most Fort Worth homeowners discover the motor has failed the same way: the gate starts moving slower in summer heat, then one day it opens halfway, groans, and stops. Or the motor hums but the gate doesn’t budge. By the time you’re searching for a replacement, the motor has usually been giving warning signs for weeks.

Which FAAC Models This Applies To

We work on the FAAC residential and light commercial lines most common around Fort Worth driveways: the 400 Series operators (including the 402, 412, and 422 swing gate motors), the 391 and 770 slide gate operators, and the S418 and S450 hydraulic swing operators. The compatibility gotcha we see again and again is this: the 412 and 422 look nearly identical from the outside, but the stroke length and mounting plate dimensions differ by several inches. Grabbing a used motor from one series and bolting it onto another is how a lot of gates end up sagging within a year.

If you can still read the data plate on your existing motor, write down the model number, voltage (most Fort Worth residential installs are 115V, but older gates sometimes run 230V), and the serial number. If the plate is sun-faded or the paint has weathered off, our techs can identify it by measuring the piston stroke and bolt pattern on site. For FAAC specifically, we lean toward OEM or factory-compatible replacement motors rather than bargain aftermarket units. The hydraulic pumps in the 400 Series run at tight internal tolerances, and we’ve seen no-name replacements burn out their bypass valves inside two Texas summers. That’s not a gamble worth taking on a gate you use twice a day.

Signs Your FAAC Gate Motor Replacement Is Failing

• The gate moves noticeably slower than it used to. Hydraulic FAAC motors lose pressure as internal seals degrade. In Fort Worth’s summer heat, that degradation accelerates. A gate that once took 12 seconds to open now taking 20 is not your imagination, and it won’t fix itself.
• The motor hums or clicks but nothing moves. The capacitor or the bypass valve has failed. On the 400 Series, this is the most common failure point we replace. The motor still has life, but it’s not getting the electrical push it needs to start under load.
• The gate stops mid-travel, then starts again after a few minutes. This is thermal overload protection kicking in. The motor is overheating because it’s working against worn gears or dragging hinges. It will get worse until something lets go completely.
• Oil or hydraulic fluid weeping from the operator housing. On the S418 and S450, a small weep trail under the unit means a shaft seal is on its way out. Once fluid level drops, the pump cavitates and the motor dies fast. This is not a cosmetic leak.
• The gate jerks or stutters in one direction only. One side of the circuit board or a relay is failing on the open side but not the close side. We see this on FAAC boards that are eight to twelve years old, right around the age of most original Fort Worth installs.

Replacement Cost & What’s Included

In Fort Worth, you’re looking at roughly $950 to $1,600 for the motor or actuator assembly itself, plus $350 to $900 in labor, depending on whether we’re doing a straight motor swap or rebuilding the mounting hardware, limit switches, and wiring harness at the same time. A 412 swing motor replacement typically lands near the bottom of that range. A full S450 hydraulic rebuild with new piston seals and fluid comes in near the top.

Everything is quoted before any work starts. You’ll know the exact number while the gate is still closed, not after it’s in pieces. The price includes the part, labor, system calibration, and a full function test of the open and close limits, reversing sensors, and safety edges. Every FAAC motor replacement we do is covered by our written 90-Day Done Right Promise. If it’s not right, we come back and make it right. No arguing, no paperwork.

DIY or Call Us?

A FAAC gate motor handles a lot of force, and the wiring inside the cabinet carries line voltage. If you’re comfortable with a multimeter, you can safely check the incoming power at the operator, confirm the circuit breaker hasn’t tripped, and verify the manual release is fully engaged. That’s useful information to have before you call.

Past that, we don’t recommend opening a FAAC motor housing yourself. The capacitors store enough charge to knock you off a ladder, and the hydraulic pressure inside the S-series operators can spray fluid hard enough to cut skin if a line is cracked. Most of the failed FAAC repairs we’re called to fix in Fort Worth started as a well-intentioned Saturday project that went one bolt too far. If the motor is dead, call us at (817) 562-7979. We’ll diagnose it over the phone or send a tech out the same day.
