FAAC Gate Motor Replacement: The Los Angeles Owner’s Guide

We stock and install FAAC-compatible gate motor replacements across Los Angeles, with most swaps running between $750 and $1,450 installed depending on the specific FAAC model and whether we’re replacing the motor alone or the full operator assembly. In most cases we can have your gate running again the same day we arrive, because our trucks carry the FAAC parts that actually fail in this city: 24V motors, capacitor assemblies, and control boards for the 400, 412, 415, and 770 series. The way owners usually find us is simple: the gate starts opening halfway, then reverses, or it hums but won’t move at all, or the keypad beeps but nothing happens and it’s been getting slower every week since spring.

If you’ve got a FAAC gate that’s acting up, this page will tell you exactly what to check, what it costs to replace the motor here in Los Angeles, and what we do differently when we do the work. Call (626) 649-4572 for a free estimate.

Which FAAC Models This Applies To

The FAAC gate motors we replace most often in Los Angeles are the 400 Swing, 412 Operator, 415, 770, and the newer S418 and S800 lines. Each has a slightly different motor assembly, and here’s the compatibility gotcha that surprises a lot of owners: the 412 and 415 look nearly identical from the outside, but the motor flanges are not interchangeable. A 415 motor won’t bolt onto a 412 gearbox without an adapter plate, and FAAC doesn’t sell one. We’ve seen at least three Los Angeles homeowners buy a used 415 motor on eBay for their 412 and end up drilling holes that weakened the mounting bracket.

To identify your FAAC model, look on the inside of the plastic cover for a silver data plate. The model number is stamped there. If the plate is faded or missing, take a photo of the operator from two feet back and send it to us; we can identify most FAAC units from the arm geometry and the shape of the release handle. The serial number’s first two digits tell you the production year, which matters more than most owners think, because FAAC made a running revision to the 400-series motor bearings in 2018 that affects which replacement motor we’d recommend.

On the OEM versus aftermarket question for FAAC specifically: FAAC factory motors are built in Bologna, Italy and they’re excellent. But for the 400 and 412 series, there’s a well-made aftermarket motor assembly from a US supplier we’ve installed for years that runs about $80 cheaper, fits without modification, and carries the same one-year functionality we give on OEM parts. We’ll quote both and let you choose. For anything newer, such as the S800, we use FAAC OEM parts, because the aftermarket options for those just aren’t good enough yet, and we don’t install parts we don’t trust.

Signs Your FAAC Gate Motor Replacement Is Failing

These are the symptoms we hear on calls across Los Angeles, from Brentwood and Pacific Palisades to the Valley, and what each one actually means:

• The gate opens halfway and stops, then slowly reverses. The motor’s torque sensor is detecting resistance that shouldn’t be there. Often it’s the motor’s internal capacitor losing its ability to hold a charge, which is the earliest wearing part on a FAAC 400-series motor in our climate. In coastal Los Angeles areas like Playa del Rey or Marina del Rey the salt air accelerates this faster than inland neighborhoods do.
• The motor hums but the gate doesn’t move. The start capacitor has failed. The motor is getting power and trying to turn, but it can’t generate enough starting torque. On a FAAC this is a $40 to $60 part, but if you keep trying to open the gate while it’s humming, you’ll overheat and cook the motor windings, turning a small repair into a full motor replacement.
• The gate opens fine but slams closed or closes in slow motion. On FAAC hydraulic operators, this usually points to low hydraulic fluid or a failing bypass valve in the pump section of the motor assembly. The motor itself may still be healthy. We check fluid level and pump pressure before recommending a motor replacement, because sometimes a $30 o-ring and fresh hydraulic oil is the actual fix.
• The gate beeps at the keypad but won’t respond, or it works sometimes and not others. This often masquerades as a motor issue but it’s commonly the control board failing to send consistent voltage to the motor. We test the board’s output before we recommend replacing the motor. A new motor won’t fix a board that isn’t telling it to run.
• The motor smells hot after a normal open-close cycle, or you hear a grinding noise from inside the housing. Grinding is usually the gear drive inside the operator housing. On a FAAC 770, the motor and gearbox are a sealed unit, so this means replacing the whole assembly. On the 400 series the motor can be replaced separately from the gearbox, which saves several hundred dollars. We’ll open it up and show you what we’re seeing before we quote anything.

Replacement Cost & What’s Included

In Los Angeles, a FAAC gate motor replacement installed by us typically lands between $750 and $1,450. The lower end of that range is a 24V motor swap on a 400-series unit where the gearbox and board are still healthy. The upper end is a full 770-series motor and pump assembly replacement with new hydraulic fluid, or an S800 motor replacement with labor, disposal of the old unit, and recalibration of the open/close limits.

What drives the difference: whether the motor is available as a separate part on your FAAC model, whether the control board also needs replacing, and whether your gate is a single or double leaf. Double-leaf gates that swing on two operators mean two motors, though the second motor rarely fails at the same time as the first. You’ll see the exact line-item cost in writing before we touch anything, including the part number we’re quoting, the labor, and any hydraulic fluid or small hardware the job requires. The price you see on the written estimate is the price you pay. Our labor and the part are both covered for a full year under the 365-Day Done Right Promise. If it’s not right, we make it right, no argument.

DIY or Call Us?

A FAAC gate motor is a 24V DC or 120V AC sealed unit, and on most models the wiring runs through a control board that can hold a stored charge even when the breaker is off. If you’re not completely comfortable de-energizing the system and verifying it with a meter, don’t open the housing. We say that plainly because we’ve seen owners try to save a couple hundred dollars and end up needing a new control board after a short. That said, there are safe checks you can do before calling us: confirm the breaker labeled “gate” or “front gate” is on, check that the manual release lever on the operator isn’t left in the open position from a recent power outage, and clear any debris or overgrown bougainvillea from the gate’s swing path. Those three things resolve a surprising number of “dead motor” calls in Los Angeles.

Where DIY goes wrong on FAAC motors specifically is the limit-switch recalibration after a motor swap. FAAC 400-series operators use fine-pitch limit cams inside the housing, and if they’re set wrong the gate will either stop six inches short of the post or push through the close point and burn out the new motor’s capacitor in weeks. We set them with the motor on the bench, connected to a meter, before we even bolt it back into your gate. If you’d rather not deal with any of that, call us at (626) 649-4572 and we’ll come out, diagnose it, and give you a written price.
