FAAC Gate Motor Replacement Nationwide

FAAC Gate Motor Replacement: The Sherman Oaks Owner’s Guide

We stock and install FAAC-compatible gate motor replacements across Sherman Oaks, and most swaps run between $950 and $1,450 fully installed, depending on your model series and whether the arm bracket survived. Same-day service is available when we have your motor on the truck, which we do for the common FAAC 400, 412, and 770 series. Owners usually find us after the gate starts grinding mid-travel or refuses to close all the way, and by then the motor has often been compensating for a failing capacitor for months.

Here’s the situation we see most often in Sherman Oaks: a FAAC hydraulic operator that worked fine for six or seven years suddenly won’t hold position, or it hums without moving, or it opens but the auto-close feature gives up. The controller’s fine. The hinges are fine. The motor itself is the failure point. Adrian Vance has replaced enough of these to tell you what you’re looking at, what your options are, and what it costs before anyone picks up a tool.

Key takeaways:

• Installed FAAC motor replacement in Sherman Oaks: $950-$1,450, written before work starts
• We stock FAAC 400, 412, 770, and select C720/S800 series motors on our trucks
• OEM and proven aftermarket options available, with compatibility verified against your serial plate
• Every job includes a photographic record and the 365-Day Done Right Promise

Which FAAC Models This Applies To

The FAAC line splits into two families that matter for replacement: the hydraulic swing-gate operators (400, 412, 415, 770, C720, S800 series) and the electromechanical slide-gate operators (740, 844, 884 series). We carry replacements for both, but the swing-gate motors are what we replace most often in Sherman Oaks, where the typical driveway is a single or double swing gate on a hillside or a slope up from Ventura Boulevard. The hydraulic motors in the 400 series and 770 series share a common failure profile: the internal pump seals degrade, fluid bypasses, and the gate loses force or drifts open. The motor can’t be rebuilt economically at that point, so replacement is the straight-line answer.

How to identify your motor before you call: the model and serial are stamped on a metal plate on the operator housing, not on the control board. Look for a label starting with a letter and three digits, like “412” or “770.” Photograph it. If the plate’s missing, measure the operator body: the 400-series housing is roughly 28 inches long, the 770 is closer to 36. That measurement plus a photo of the arm bracket tells us most of what we need. One compatibility gotcha: the FAAC 412 uses a different arm geometry than the older 402, even though the housings look nearly identical, and installing the wrong arm kit on a new motor will destroy the limit mechanism within months. We check this every time.

On the OEM-versus-aftermarket question for FAAC specifically: FAAC parts are quality, but their replacement motors are priced at a premium, and their distribution can be slow. We stock both OEM and a proven aftermarket line that carries comparable specs and a solid reliability record with our customers. The aftermarket option often saves $150 to $250 without cutting corners on torque or duty cycle. We’ll show you both prices and the spec comparison, and you choose. We are an independent Sherman Oaks gate repair company, not a FAAC dealer or affiliate, so the only thing we steer toward is the part that fits your gate and your budget.

Signs Your FAAC Gate Motor Replacement Is Failing

In Sherman Oaks, FAAC motors tend to give you warning signs before they quit entirely. Here are the five we see most often:

• The gate hums but won’t move. The motor’s running, but the hydraulic pump isn’t generating pressure. Usually a failed pump seal or a stripped internal gear. This is a hard stop: if you hold the button and force it, you’ll destroy the arm bracket too.
• The gate opens partway and reverses. The motor is overheating or the obstruction sensor is reading resistance that shouldn’t exist. On older FAAC units, this often traces back to a failing capacitor or a partially seized motor bearing. Either way, the motor’s drawing too much amperage and the controller is protecting itself.
• The gate drifts closed or open after every cycle. The motor’s internal seals are letting fluid bypass, so the gate can’t hold position. This is a classic 770-series failure in warm climates; heat cycles eventually crack the piston seals.
• It growls or grinds during travel. Metal-on-metal noise from inside the operator is never good. It’s usually either a failed thrust bearing or a worn worm gear in the pump assembly. Both mean the motor has to come out.
• The auto-close feature stopped working. The controller is compensating for a motor that’s no longer reaching full close pressure. Don’t just disable auto-close and live with it: the motor is telling you the end is near.

One honest note on safety: these are hydraulic and electromechanical motors under load. The arm is under tension, and there’s 120V at the operator. We don’t recommend opening the housing and poking at the pump without training. If you want to check anything, check the gate itself: open and close it manually with the operator released, and see if the gate moves freely. If it does, the motor is the culprit. If it doesn’t, you have a hinge or wheel problem that a new motor won’t fix, and a good technician will catch that before selling you a replacement.

Replacement Cost & What’s Included

Installed FAAC gate motor replacement in Sherman Oaks runs $950 to $1,450 for most residential swing-gate setups. Slide-gate motor replacements typically fall in the $1,100 to $1,600 range, with the added cost coming from the rack-and-pinion alignment and longer cable runs. Here’s what drives the range:

• Motor part cost: $450-$700, depending on OEM vs. aftermarket and the series
• Labor: $350-$550, including removal, bracket inspection, motor mount, limit adjustment, and controller programming
• Arm bracket and linkage replacement: $0-$200, if the old bracket is bent or the knuckle joints are worn
• Photo-eye or safety edge replacement: $85-$220, if they were damaged in whatever event took out the motor

The written price you get from us covers all of it: the motor, the labor, the setup, and any small hardware that’s needed. If we open the job and find something unexpected, we stop, photograph it, show you, and give you a revised written price before touching anything else. That’s Clause 1 of our Haven Standard, and it’s how we’ve done every job since Adrian Vance started this company in 2014. All replacement work carries the 365-Day Done Right Promise: if it’s not right, we make it right, no argument, no fee.

DIY or Call Us?

What’s safe to do yourself: release the operator with the manual key, move the gate by hand to check for hinge or wheel binding, and photograph the model plate so you know exactly what you’re working with. Those three steps take ten minutes and tell you whether the problem is the motor or the gate. What’s not safe: opening a live FAAC operator, disconnecting hydraulic lines, or attempting a motor swap on a gate that’s still connected to power and under tension. Hydraulic fluid under pressure is not something you want to learn about the hard way, and a gate arm releasing under load can break an arm or a knuckle.

We’ve also seen a few DIY replacements go wrong in a specific way: the motor bolts up fine, but the limit switch travel isn’t set for the new arm geometry, and the gate slams into the stop at full speed. That’s a $600 mistake on top of the part cost. If you’re considering doing this yourself, call us anyway. We’ll tell you honestly whether it’s a job you can manage. If it’s not, we’ll handle it. Call (213) 463-6296 and we’ll give you a straight answer.
