FAAC Gate Motor Replacement: The Granada Hills Owner’s Guide

FAAC gate motor replacement in Granada Hills typically runs $850 to $1,700 installed, depending on which FAAC series you have and whether the arm, capacitor, or control board needs replacing alongside the motor. We stock FAAC-compatible motors for the 400, 412, and 750 series on the truck and can usually have your gate working again the same day we show up. What most owners tell us before they call: the gate starts moving slower than it used to, then one morning it just hums and doesn’t move at all. That’s the classic FAAC failure pattern in our climate. The San Fernando Valley heat bakes electrolytic capacitors inside the control box, and once those weaken, the motor works harder until it finally gives out. If you’ve got a FAAC operator that’s humming, stalling, or tripping its breaker, the motor replacement itself is usually the fix, but matching the right model and arm assembly matters more than most folks realize.

Which FAAC Models This Applies To

FAAC has built swing gate operators for residential and light commercial use under several series numbers, and the motor you need depends on which one is bolted to your gate. The 400 series is the most common residential unit we see in Granada Hills, used on iron and steel driveway gates up to about 14 feet. The 412 is its direct descendant with a slightly different gearbox ratio and a different capacitor rating, so the motors do not swap cleanly between the two. The 750 series is the heavier-built unit, often found on longer or wind-exposed gates, and its motor costs more because it’s a more substantial assembly. How to identify yours: open the cover on the operator and look for the silver data plate. FAAC stamps the model number, serial number, and sometimes the year of manufacture right there. If the plate is gone or sun-faded, measure the operator body and take a photo of the arm assembly and we’ll match it.

A word on OEM versus aftermarket: FAAC OEM motors are well made, but they’re also priced like imported Italian equipment, and lead times can stretch if a distributor is out of stock. Quality aftermarket equivalents exist for the 400 and 412 series, and honestly, we’ve installed enough of them to know they hold up fine in Southern California weather when matched to the correct capacitor. Where we get picky is using an undersized or generic replacement, because a motor rated for a lighter load will burn itself out on a heavy gate inside a year. That’s a repair we’d rather do once.

Signs Your FAAC Gate Motor Replacement Is Failing

• The gate hums but doesn’t move. This usually means the motor is getting voltage but the start capacitor has failed, so there’s no initial torque to get the arm moving. Common on 400 and 412 series units over five years old.
• The gate moves noticeably slower than it did a year ago. Motor windings degrade with heat cycling, and Granada Hills summers accelerate that. If your gate used to open in 12 seconds and now takes 25, the motor is working against itself.
• The operator trips its breaker or blows a fuse mid-cycle. That’s the motor pulling more current than the board will allow, and it will only get worse. We see this on gates where the hinge post has shifted and the gate now drags against its travel path.
• The gate opens halfway and reverses. FAAC control boards use current sensing to detect obstructions. A failing motor that draws irregular current can trip that safety feature even when nothing is in the way.
• The operator runs but the arm barely engages. On FAAC units with a mechanical release, a worn gearbox or sheared key inside the arm coupling can be the real problem. The motor still spins; it just isn’t moving the gate.

Replacement Cost & What’s Included

In Granada Hills, expect to pay between $850 and $1,700 for a complete FAAC motor replacement, parts and labor. Entry-level pricing covers a 400 series aftermarket motor swapped into an existing arm assembly, assuming the arm, capacitor, and control board are still good. Higher-end pricing reflects a 750 series motor, or any job where the capacitor, motor, and worn arm components all need replacing at once to do it right. We quote the full price before any work starts, and that number is what you’ll pay when we’re done unless we find something significant mid-repair, in which case we’ll call you and agree on the change before touching it. Our 90-Day Done Right Promise applies to every motor replacement in writing. Gray area: if the gate itself is poorly aligned or the hinge post is shifting, a new motor will fail early. We’ll tell you that before we sell you one.

DIY or Call Us?

There are a couple of things any homeowner can safely check: confirm the operator has power at the outlet, and look for a tripped breaker or a kill switch on the control box that got bumped. After that, you’re dealing with 120-volt wiring, a capacitor that stores charge even with power off, and gate arms under mechanical tension. That capacitor can knock you on your back if you touch the terminals, so we’re going to say this plainly: leave the motor swap to someone who does it for a living. FAAC units in particular have tight clearances inside the operator housing, and forcing a motor into place can crack the casting. What usually ends up in our shop after a DIY attempt is a half-disassembled operator with sheared screws and a control board that got shorted by a dropped wrench. That’s a more expensive fix than the original motor. If you’re in Granada Hills and the gate won’t move, call (760) 361-6706 and we’ll come take a look.
