FAAC Gate Motor Replacement: The Dallas Owner’s Guide
FAAC gate motor replacement in Dallas typically runs between $950 and $2,400 installed, depending on the model series, whether you need the full motor-and-arm assembly or just the motor unit, and whether your existing mounting hardware is still sound. We stock FAAC-compatible motors and arms on our trucks for the most common Dallas installs, so most replacements happen in a single visit. The way owners usually discover this: the gate starts cycling slower, then stops mid-travel, then sits there humming while the control board blinks a fault code.
If you’re reading this, you’ve probably already noticed the hum, the hesitation, or the gate that won’t quite close. What you’re looking at is a motor that’s lost torque, a capacitor that’s given up, or a gear that’s stripped inside the housing. We’ll tell you which one it is before we touch a wrench, because the written price depends on it.
Which FAAC Models This Applies To
FAAC breaks its residential lineup into swing-arm operators (the 390, 391, 400, 412, 415, and the newer S418 and C720 series) and slide-gate operators (the 740, 741, 844, and the long-running S800 series). The motor unit itself is not universal across these lines. A 390 motor will not drop into a 400 housing without modification, and a 415 arm assembly has a different mounting geometry than the 412 it visually resembles. We’ve seen Dallas homeowners buy a used motor online, get it home, and find the mounting ears are off by a quarter inch.
Here’s the compatibility gotcha worth knowing: FAAC stamps a part number on the motor housing, but the series number that matters is on the operator’s metal nameplate, usually near the manual release. Write that down before you call anyone. If the nameplate is weathered off (Texas sun does that in about four years on unshaded gates), we identify the unit by shaft length, mounting bolt pattern, and the control board revision. We also carry quality aftermarket equivalents for the most common FAAC swing motors. For gate operators still in production, we recommend OEM. For discontinued series like the 390, a well-built aftermarket motor with the same shaft spec and the same duty rating is often the smarter spend than hunting for new-old-stock at a premium.
Signs Your FAAC Gate Motor Replacement Is Failing

- Gate moves slower than it did a year ago, especially in the last foot of travel. That’s torque loss, which in a FAAC motor usually means the run capacitor is degrading or the gear teeth are wearing. Neither gets better on its own.
- Motor hums but the gate doesn’t move. The capacitor has failed, or the drive gear has stripped. If it’s a capacitor, it’s a $40 part and fifteen minutes. If it’s the gear, the motor replacement conversation starts.
- Gate jerks or stutters mid-cycle, then continues. You’re feeling a dead spot in the motor windings or a chipped gear tooth. We see this most on older 390 and 400 series operators in Dallas that have run 10,000-plus cycles in actual heat.
- Overload fault trips repeatedly on the control board. The motor is drawing more current than the board will allow. If the gate is balanced and the hinges are greased, the motor itself is the draw.
- Burning smell after a cycle, or the motor housing is too hot to touch for more than a second. Motor windings are cooking. Stop running the gate, cut power at the breaker, and call. A cooked motor can take the control board with it if it shorts.

AfterReplacement Cost & What’s Included
For Dallas single-family swing gates, a FAAC motor replacement lands between $950 and $2,400 installed. The spread depends on the series, whether we’re replacing just the motor or the motor plus the arm assembly, and whether your existing brackets are reusable. Slide-gate replacements on the 740 and 844 series run closer to $1,400 to $2,800 because the motors are heavier-duty and the rack-and-pinion engagement has to be set on site.
Every quote includes the motor or arm assembly, all mounting hardware, limit and torque adjustments, a full cycle test, and the photo log we leave on every job. Here’s the pricing breakdown for the most common FAAC replacements in Dallas:
| Replacement Type | Typical Installed Range |
|---|---|
| FAAC swing motor only (390 / 400 / 412 / S418) | $950 - $1,600 |
| FAAC swing motor + arm assembly (390 / 400 / 415) | $1,400 - $2,400 |
| FAAC slide motor (740 / 741 / 844 / S800) | $1,400 - $2,800 |
| Run capacitor replacement (minor fix, not full motor) | $120 - $240 |
The price you’re quoted is the price you pay. It’s written down and handed to you before we unbolt anything. No surprise invoice, no “while we’re in there” upsell. That’s Haven Standard Clause 1, and it’s not negotiable on our end. The replacement work is covered by our 365-Day Done Right Promise. If the motor or the install isn’t right within a year, we make it right at no charge.
DIY or Call Us?

Here’s the honest split. You can safely check a few things yourself: confirm the breaker isn’t tripped, verify the manual release isn’t half-engaged, look at whether the gate is visibly off-level. You should not open the motor housing or attempt a motor swap. FAAC motors run on line voltage, the capacitor inside holds a charge even after the breaker is off, and a slip with a screwdriver on a charged capacitor is a genuine injury risk. We’ve also seen DIY replacements where the new motor bolted in fine, but the limit switches were never set, and the gate slammed through the stop the first cycle.
If you’ve got a FAAC symptom on a gate in Dallas and you want it diagnosed in plain English, call (469) 299-5902. We’ll tell you whether it’s a motor, a capacitor, a board, or nothing worth replacing at all. The estimate is free, and it’s in writing.
FAQs
In Dallas, a residential FAAC motor typically lasts 7 to 12 years, assuming the gate is balanced and the operator was installed correctly. Texas heat shortens that lifespan: a motor on an unshaded west-facing gate in Lakewood or Preston Hollow runs hotter every afternoon, and heat is what kills capacitors and cooks winding insulation. If your FAAC is past year eight and cycling slowly, start budgeting for a replacement.
Sometimes. If the failure is a run capacitor, a start relay, or a wiring terminal, we repair it on the spot and you’re looking at $120 to $300. If the windings are shorted or the gear is stripped, repair doesn’t make sense. Quick way to know which one you’ve got is to call (469) 299-5902 and tell us the exact symptom, and we’ll tell you over the phone what’s most likely.
A standard FAAC swing motor replacement on a single-family gate in Dallas takes two to four hours on site, including removing the old unit, mounting the new one, setting limit switches and torque, and running a full cycle test. If we’re also replacing the arm assembly or the gate itself needs a balance adjustment, figure a half day. We stock the most common FAAC motors on the truck, so there’s usually no waiting on parts.
We stock FAAC-compatible swing motors for the 390, 400, 412, and S418 series, plus common slide-gate motors for the 740 and 844 series, on our service vehicles in Dallas. If your FAAC model is less common, we can usually have the right motor in hand within one to two business days. We also carry parts for LiftMaster, Mighty Mule, and Ghost Controls if you’re weighing your options or have a second gate on the property with a different brand.
The Bottom Line

A FAAC motor that’s humming, slowing, or tripping the board is a motor telling you it’s done. The replacement is straightforward for a technician who works on these every week, and it’s the difference between a gate you trust and a gate you hold your breath waiting on. We’ll show you the part number we’re installing, the price before we start, and the photos when we leave. If you’re in Dallas and your FAAC is failing, call (469) 299-5902. A live person answers, any hour, and you’ll have a straight answer before you hang up.
