FAAC Gate Motor Replacement Nationwide

FAAC Gate Motor Replacement: The Irving Owner’s Guide

We stock and install FAAC-compatible gate motor replacements across Irving, and most single swing-gate replacements run between $1,450 and $2,800 installed, depending on your exact FAAC model and whether the existing arm geometry and mounting plate can be reused. We keep FAAC 400, 412, 415, 770, 391, and C720 series motors and control boards in our Irving service van, so most jobs are completed the same visit.

Most Irving homeowners find out their FAAC motor has failed the same way: the gate stops mid-travel, the opener hums but nothing moves, or the panel throws a fault code that resets but comes back within a day. FAAC units are generally reliable, but ten years of Texas heat and humidity take a toll on capacitors, limit switches, and the hydraulic pump seals. When a motor reaches that point, a replacement is usually the honest call, not another patch job.

Which FAAC Models This Applies To

FAAC has used several model naming conventions over the years, and the plate on your motor tells us most of what we need. The most common FAAC gate operators we replace in Irving are:

• FAAC 400 and 402 hydraulic operators – the classic underground-style swing arm, heavy and long-running. Pump seal failure is the usual end-of-life cause. We replace the pump unit, not the whole underground box, when the foundation and spindle are still sound.
• FAAC 412 and 415 compact operators – lighter duty, common on residential single gates. Capacitor failure is frequent. A replacement motor with a fresh capacitor and limit assembly typically runs less than a full hydraulic rebuild.
• FAAC 770 and C720 series – the current-generation 24V electromechanical units. Control board failure is more common than motor failure here, and we always test the board before quoting a motor, because the board is a $300 part and the motor is a $900 part.
• FAAC 391 and 390 series – older linear screw-drive units seen on sliding gates in Irving’s Las Colinas corridor. Screw wear is gradual, but when the nut strips, the motor follows quickly.

Here is the compatibility gotcha most owners miss: FAAC 400 parts do not interchange with 412 parts, even though both are “hydraulic FAAC swing gate motors” and look similar at a glance. The shaft diameters differ by 6mm, and the mounting bolt pattern is not shared. We verify the motor model from the ID plate before we order or install anything. On the OEM versus aftermarket question, for FAAC specifically we recommend OEM motor bodies paired with aftermarket capacitors and limit switches. The motor body is the precision part; the wear items around it are commodities. That combination has given our Irving customers the best reliability per dollar without overpaying for a brand sticker on a capacitor.

Signs Your FAAC Gate Motor Replacement Is Failing

• The gate starts, then stops and reverses. This is usually a failing torque limiter or a hydraulic bypass valve that no longer holds pressure. The motor thinks it hit an obstruction. It didn’t. The pump is bleeding internally.
• The motor hums but the gate doesn’t move. On hydraulic FAAC units, this means the pump is running but not building pressure. That is a worn pump gear or low hydraulic fluid from a slow seal leak. On electromechanical units, it is often a stripped drive gear.
• Fault codes appear and clear repeatedly. FAAC boards store fault history. A code that clears on reset but returns within a day points to a dying motor drawing excess current or a limit switch starting to wander.
• The gate moves slower than it used to, especially in summer. Dallas-area heat thins hydraulic fluid and accelerates internal wear. A motor that was brisk in March and sluggish in August is telling you the pump clearances are opening up. That does not heal itself.
• You smell a burnt odor near the operator cover. That is overheated motor windings or boiling hydraulic fluid. If you smell it, kill power to the operator and leave it off. Running it again can damage the control board too, and that doubles the repair bill.

Replacement Cost & What’s Included

In Irving, a FAAC gate motor replacement lands in a predictable range based on the model and what we are reusing:

• FAAC 412 / 415 replacement motor and capacitor: $1,450 to $1,800 installed
• FAAC 400 hydraulic pump unit replacement: $1,900 to $2,400 installed
• FAAC 770 / C720 motor replacement: $1,600 to $2,100 installed
• FAAC 391 / 390 screw-drive motor replacement: $1,800 to $2,300 installed
• Full operator swap (new motor, board, limit assembly, arm): $2,400 to $2,800 installed

Those numbers include parts, labor, travel within Irving, limit setup, force adjustment, and a full function test. The price you are quoted is the price you pay. We hand you the written quote before any work begins, and if we find the mounting plate needs fabrication or the arm geometry has to change, we stop and get your approval in writing before adding a dollar. Every FAAC motor replacement we install carries our 365-Day Done Right Promise: if something is not right within a year, we make it right at no additional charge.

DIY or Call Us?

There are two things an Irving homeowner can safely check before calling us. First, confirm power is reaching the operator. A tripped GFCI outlet or a flipped breaker on the gate’s dedicated circuit accounts for a surprising number of “dead FAAC” calls, and that fix costs nothing. Second, look at the FAAC control board for obvious signs of moisture or burned components. If the board looks clean and the operator still will not run, stop there.

The hydraulic side of a FAAC 400 holds pressure even when unpowered. Opening the wrong fitting can spray fluid under force, and the moving arm on any FAAC unit can crush fingers if the manual release is not correctly engaged first. We have seen the injuries from both. Motor replacement is not a weekend project on this equipment. If it is not the breaker, call us at (817) 510-4183 and we will send a technician who carries FAAC motors and boards on the truck.
