FAAC Gate Motor Replacement: The Tomball Owner’s Guide
A FAAC gate motor replacement in Tomball typically runs between $950 and $1,650 installed, depending on which FAAC series you have and whether the mounting bracket and arm assembly are still intact. We stock FAAC replacement motors for the 400, 412, 760, and 770 series on our trucks, and most two-hour swaps happen the same day we quote them. The way most Tomball homeowners discover the motor has failed is simple: the gate starts moving slower than it did last month, then one morning it grinds, hums, and doesn’t move at all.
When you call, we’ll ask you to read the tag on the side of the motor housing. That tag tells us the series, the voltage, and the production year. We’ll bring the right part the first time, and the price we quote before we start is the price on the invoice when we leave.
Which FAAC Models This Applies To
FAAC has made gate operators for decades, and not every motor fits every FAAC housing. The 400 series runs on 115V and uses a hydraulic pump with a separate motor block. The 412 is the 24V version of the same basic platform. The 760 and 770 series are the newer electromechanical swing-gate operators, and the motor for a 760 will not bolt into a 770 without a different mounting plate, even though the arm geometry looks nearly identical to the eye.
The compatibility gotcha we see most often in Tomball: a homeowner buys a motor online thinking all FAAC swing motors are interchangeable, and the bolt pattern is off by roughly 40 millimeters on the mounting flange. Get us a photo of the tag before you order anything, or read us the model off the tag over the phone, and we’ll tell you the exact replacement part number. FAAC OEM motors carry a cleaner warranty and a longer production history than most aftermarket equivalents, but an aftermarket motor from the same Italian factory lineage can run $150 to $250 less. We stock both and will tell you the difference in plain terms before you spend a dollar.
Key Takeaways
- Tomball installed replacement cost: $950-$1,650 for most FAAC swing-gate motors.
- Series matters: 400, 412, 760, and 770 are not interchangeable.
- Read the tag on the motor housing before ordering any part.
- We stock FAAC-compatible motors on the truck and replace most the same day.
Signs Your FAAC Gate Motor Replacement Is Failing

- Gate opens halfway and stops. The motor’s thermal overload protector is tripping because the winding insulation is breaking down from age. In Tomball’s summer heat, a ten-year-old motor that would run all day at 80 degrees will trip at 98 degrees after eight minutes.
- You hear a hum and no movement. The start capacitor on the single-phase 400 series is the most common failure point. It’s a $12 part, and we replace it on-site when that’s the only issue, but if the motor windings have pulled the cap down, the motor itself goes next within weeks.
- The motor runs but the gate creeps or slips. The hydraulic pump inside the 400-series housing has lost pressure, or the release valve bypass is partially open. We measure the operating pressure with a gauge rather than guessing. The motor may still be fine; the pump block may not.
- Burnt-electrical smell near the operator box. This is winding failure, and it’s not a repair. Stop using the gate until we can look at it. A motor that scorches its windings can take the control board with it if it shorts while powered.
- The gate stops at the wrong position every time. The limit assembly inside the motor drives off a plastic cam that strips with age. On a 760, the cam set is replaceable. On older 400s, the internal limit mechanism is often the trigger point that makes replacement cheaper than a third teardown.

AfterReplacement Cost & What’s Included
Most FAAC gate motor replacements in Tomball land between $950 and $1,650 installed. Where you land in that range depends on three things: the series (400 and 412 motors run lower than 760 and 770), whether the arm bracket and worm-gear coupling are reusable, and whether we’re doing a straight motor swap or the pump block and capacitors have to come out with it.
Every quote includes the motor itself, the mounting hardware, new wire terminals, the limit calibration, and the photo record we leave behind. We write the price on the work order before the first tool comes off the truck, and we don’t add a “discovery fee” or a “parts surcharge” after the fact. The 365-Day Done Right Promise covers the entire replacement; if it isn’t right, we make it right, no argument, no fee, no expiration date within that year.
DIY or Call Us?

Replacing a FAAC gate motor means working with 115V or 24V supply wiring, the capacitor, and a moving metal arm that can take off a finger if the release is pulled while the arm is under load. We don’t recommend opening the motor housing unless you have electrical experience and a multimeter you know how to use on live circuits. The voltage present even with the system “off” at the breaker is enough to stop a heart.
What you can safely check is the tag on the motor, the condition of the arm bolts, and whether a tripped breaker is the only symptom. If the motor hums, smells burnt, or has been struggling for months, call (346) 248-7685 and we’ll come out, diagnose it in front of you, and hand you a written price before any work starts.
FAQs
Expect 8 to 12 years from a well-maintained FAAC motor in Tomball, with heat and humidity being the two biggest factors that shorten lifespan. The 400-series hydraulic units often outlast the newer electromechanical ones in Texas because the oil bath protects the internals better. Call (346) 248-7685 if your motor is older than ten years and you suspect it’s losing torque.
Sometimes yes, and we’ll tell you if the capacitor, limit cam, or a wiring fault is all that’s wrong. But when the windings have failed or the motor is tripping the thermal breaker repeatedly in normal Tomball heat, replacement is the honest fix. We never sell a replacement when a $12 capacitor would have done the job, and our written diagnosis shows you exactly what we found.
A straight FAAC motor replacement without hydraulic or bracket complications takes about two hours from setup to final limit calibration. We do most of them same-day in Tomball. If we need to order a specific part for your exact series, we’ll tell you the lead time before we schedule anything.
We stock replacement motors for the FAAC 400, 412, 760, and 770 series on the truck, along with capacitors, limit kits, and arm bushings. We also stock compatible parts for LiftMaster, Mighty Mule, Ghost Controls, and the other brands we service, so we’re not pushing you toward a whole new system when one motor is the problem.
If your FAAC gate motor has been failing slowly or just died this morning, call (346) 248-7685. We’ll identify the exact motor your gate needs, hand you a written price before the work starts, and leave you with a photo record of everything we installed and adjusted. No guessing, no surprise invoice, no “call for a quote” runaround.
