FAAC Gate Motor Replacement Nationwide | Gatewood Fence & Gate

FAAC Gate Motor Replacement: The Van Nuys Owner’s Guide

We stock and install FAAC-compatible gate motor replacements across Van Nuys, with most single-arm swings costing between $1,100 and $1,900 installed, and slide gate motors typically landing between $1,300 and $2,200 depending on your exact model and column or rack prepping. If you call (951) 749-5734 this morning, we can usually have a truck in your Van Nuys driveway this afternoon. Most folks don’t wake up thinking about gate motors. They walk out to leave for work, hit the remote, and the gate groans, stutters, or does nothing at all. That’s usually the moment the motor gets blamed.

Here’s the part nobody tells you: sometimes the motor isn’t even dead. We see FAAC units in Van Nuys get condemned by other companies when the real problem is a voltage drop from a tired circuit, a misaligned limit switch, or battery corrosion in the backup tray. So before we ever swap a motor, we test the whole circuit. Hal Gatewood’s been repairing these things since 2001, and he’d rather tell you the motor is fine than sell you one you don’t need.

Which FAAC Models This Applies To

FAAC has been building 24-volt hydraulic and electro-mechanical gate operators for decades, and the model landscape in Van Nuys is mixed. We mostly see four workhorses in the field: the 400 series, the 412 series, the 740/750 hydraulic sets, and the newer S418 and S450H slide operators. Each of those uses different motors, different capacitor specs, and different mounting geometry, so a motor from a 412 won’t slide into a 400 bracket without re-drilling and usually re-wiring too.

The easiest way to identify what you have is to remove the plastic cover and look at the metal label riveted to the chassis. Here’s the gotcha that catches people: FAAC labels the operator model, not always the motor itself. A 412’s die-cast motor housing may only carry a stamped part number like 630004 or 630103. If your label is faded or missing, measure the mounting bolt spread and take a photo of the capacitor. We can identify it visually in about thirty seconds. We carry OEM FAAC motors and quality aftermarket equivalents on the truck, but we’ll tell you straight which one makes sense. On an older 400 series pump unit, an aftermarket motor with new brushes often makes more financial sense than an OEM unit costing more than the gate is worth. On a newer S418 under warranty, we’d point you back to OEM without blinking.

One more Van Nuys reality check: FAAC changed the shaft dimensions on certain 740-series motors mid-production around 2012. If your system predates that shift, a modern OEM motor will not fit your existing worm gear assembly without a shim kit. When we look up your unit, we check the serial number, not just the line name. That one detail has saved people hundreds of dollars.

Signs Your FAAC Gate Motor Replacement Is Failing

• The gate starts moving, then stops and reverses. This usually points to a motor drawing too much amperage, or a hydraulic bypass valve sticking. The control board sees the spike, assumes an obstruction, and reverses.
• You hear a low humming but no movement. That’s often the start capacitor or the brushes gone soft. The motor gets voltage but can’t build torque to overcome the gate’s mass.
• The gate moves slower than it did six months ago. In Van Nuys heat, hydraulic fluid thins as it ages and internal seals lose tolerance. Slowness is usually mechanical drag, not electronics, which is why we always check the post and hinge load before we point at the motor.
• The motor runs for a second and trips the breaker. This is a classic shorted winding. It’s also the point where you stop flipping the breaker back on and call somebody. An internally shorted motor will take the control board down with it if you keep feeding it.
• A burned electrical smell or visible scorch marks near the motor housing. This one is past diagnosis. The motor is gone. The question is what caused the overheat, and that’s what we’ll trace before installing the replacement.

Replacement Cost & What’s Included

The installed cost of a FAAC gate motor replacement in Van Nuys typically runs between $1,100 and $2,200 depending on whether it’s a swing or slide operator, single or double leaf, and whether the new motor requires new mounting plates or capacitor trays. The motor itself is usually $400 to $900 of that bill. The rest is labor, testing, and tuning, because a motor bolted in without checking the capacitor, the limit cams, and the load balance won’t last.

When we quote you a price, it’s the price. We don’t show up with a lower number and then find a reason to add $300 at the end. The price is quoted and agreed before any work starts, and it’s on paper if you want it. We also stand behind the work with our 90-Day Done Right Promise. If the motor or the install isn’t right within 90 days, one call brings Hal back. No runaround, no service queue.

And because this comes up often: if you got a written estimate from someone else and the numbers seem off, bring it. We’ll give you a free second opinion.

DIY or Call Us?

Let’s be honest about this one. A FAAC gate motor is not a garbage-disposal swap. These are 24-volt systems, so the shock risk is lower than line voltage, but the mechanical risk is real. A gate leaf losing support during a motor swap can crush a hand or pin a body. The springs on a swing gate carry tension you can’t always see, and a slide gate’s chain can catch a glove and pull. Our advice: if you can safely cut power at the breaker and you just want to inspect the capacitor or look for swollen wires, that’s fine. But once you’re unbolting the motor from a loaded gate, call someone who’s done it a few hundred times.

We’ll fix it in your driveway, not haul it to a shop. Hal welds on site, and if your motor cooked itself because a hinge post sagged, you want him to see that post while the gate is still hanging. Fix the motor without the post and you’ll fix it twice. Call (951) 749-5734 and we’ll put eyes on it.

How Long Does a FAAC Gate Motor Last in Van Nuys?

Across most of Van Nuys, you’ll get 7 to 12 years from an FAAC motor before brushes, capacitors, or seals give out, and that range depends heavily on how often the gate cycles and whether the previous installer balanced the leaves. A gate that fights its own weight kills a motor twice as fast. We regularly see 15-year-old 400-series motors still running in shaded parts of the Valley, and 6-year-old failures on gates that were never properly shimmed after the concrete settled. The motor doesn’t exist in a vacuum.

Can You Repair a FAAC Gate Motor Instead of Replacing It?

Sometimes, yes. If the brushes are worn but the commutator isn’t scarred, we can rebuild the motor and save you a few hundred dollars. If the windings have shorted or the armature is burned, you’re buying a motor. We’ll tell you which one it is before we touch a single bolt.

Do You Stock FAAC Replacement Parts or Do I Have to Wait?

We keep the most common FAAC motors, capacitors, and limit-switch kits on the truck, and our shop is stocked with parts for nine major brands including LiftMaster, Mighty Mule, and Ghost Controls. If your motor is an oddball, we can usually have it within two to three business days. Either way, you’ll know the timeline before anything gets disconnected.

Do You Handle Commercial FAAC Slide Gates Too?

We do. Commercial slide operators in Van Nuys get hammered by heavy cycle counts, and the S418 and S450H series are in our regular rotation. If it rolls on a track or rides a chain, we can replace the motor and button it up same day in most cases. Call (951) 749-5734 and we’ll quote it straight.
