FAAC Gate Motor Replacement: The Calabasas Owner’s Guide
A FAAC gate motor replacement in Calabasas typically runs between $850 and $1,900 installed, depending on the model line and whether you’re replacing just the motor/gearbox assembly or the full operator unit. We stock OEM and quality aftermarket FAAC-compatible parts on our trucks, so most replacements are completed in a single visit. If you’re reading this because the gate stopped mid-swing or the motor hums but nothing moves, you’ve found the right page.

The way most Calabasas homeowners discover they need this part is straightforward. The gate opens when it wants to, not when it should. Or it opens halfway, groans, and sits there. Or the control board clicks, the motor draws current, and the gate does nothing at all. That’s a failed FAAC gate motor, and it will not heal itself. Here’s what you need to know before you spend a dollar.
Which FAAC Models This Applies To
FAAC builds several distinct motor families, and the wrong match wastes your money. The primary residential and light-commercial lines we see in Calabasas are the 400 Series (swing leaf operators), the 750 and 770 Series (underground operators), and the 390 and 391 Series (articulated arm operators). Each uses a physically different motor assembly, and none swap between series.
Here’s the compatibility gotcha most owners miss: FAAC changed motor coupling designs between early and late production runs of the 400 Series. An operator built before roughly 2012 may need an adapter plate even when the motor’s part number matches. We verify this on-site before ordering, so you don’t eat a return-shipping cost. The motor label carries a serial number and build date. If the label is faded or painted over, we pull the operator cover and identify the assembly by mounting pattern and shaft diameter.
On OEM versus aftermarket: FAAC OEM motors carry a premium, and for newer operators still under their original warranty period, OEM makes sense. For a ten-year-old 400 Series in Calabasas sun, a quality aftermarket motor with equivalent torque and RPM ratings does the same job for 25 to 35 percent less. We’ll quote both options and let you decide. We’re an independent gate company, not affiliated with FAAC directly, so our recommendation follows the piece of metal, not a brand contract.
Signs Your FAAC Gate Motor Replacement Is Failing
- Motor hums, gate doesn’t move. The start capacitor or internal gearing has failed. On FAAC operators, this is the single most common failure mode after five to eight years in service. The motor is getting power and trying to work; the mechanical output is gone.
- Gate opens, then stops partway with no obstruction. Thermal overload protection is tripping inside the motor. As windings age or bearings wear, the motor draws more current, runs hotter, and shuts itself down mid-cycle. It resets after cooling, then does it again.
- A grinding or whining noise from the operator. Internal gear wear. FAAC nylon reduction gears are designed to fail before the worm shaft does. When you hear metal-on-metal, the damage has already moved past the sacrificial part.
- The gate drifts closed or creeps open while parked. Motor brake failure. FAAC operators use an integrated electromagnetic brake. When the brake coil burns out or the brake disc wears thin, the gate can no longer hold position.
- Intermittent operation, especially after a hot Santa Ana afternoon. Failing motor windings don’t like heat. Calabasas summers push already-degraded insulation over the edge. The motor works in the morning, quits at 2 p.m., and works again by evening.
Replacement Cost & What’s Included
For Calabasas specifically, here’s what installed FAAC gate motor replacement pricing looks like in today’s market:
- Motor/gearbox assembly replacement (400 Series swing): $850-$1,250 installed
- Motor assembly replacement (750/770 underground): $1,200-$1,900 installed, depending on excavation and water ingress repair
- Full operator replacement (motor, control board, arm): $1,700-$2,600 installed
- Aftermarket motor option: subtract roughly $150-$350 from the OEM figure depending on the model
Your price is quoted before we turn a bolt. Every job includes the motor, any required adapter or coupler, labor to remove and reinstall, limit-setting and force adjustment after install, and a test cycle of the full travel.

DIY or Call Us?
Here’s the honest split. If your FAAC operator is dead because the breaker tripped or a wire loosened in a junction box, you can check that yourself in ten minutes with a non-contact voltage tester. If the motor drives a gate that doesn’t move, or makes noise, or trips its overload, stop there. Gate motors of this class are heavy, gear-driven, and under mechanical load from the gate leaf. Improper removal can send a gate leaf swinging free or drop a 40-pound operator on your hand. This is work for someone who has done it enough times to know what will go wrong before it goes wrong.
Victor Salinas has diagnosed and replaced these specific FAAC assemblies in Calabasas for the better part of four decades. His training started in the welding and metal fabrication program at Pierce College in Woodland Hills, where an instructor told him early that a gate is only as honest as the weld holding it together. That lesson applies to the motor too. If the gate is giving you trouble, there is a reason, we just have to find it.

FAQs
A properly maintained FAAC gate motor in Calabasas typically lasts 8 to 12 years. Salt air for those near Malibu’s edge, fine dust from the foothills, and prolonged heat exposure between June and October all work against that figure. Operators tightened and tested annually tend to reach the upper end.
Sometimes. If the failure is isolated to the start capacitor, brake coil, or a single bearing, the motor can often be repaired in place for a lower cost than replacement. If the windings have shorted or the gear train is grinding, replacement is the better financial decision in almost every case. We’ll tell you which side you’re on before you spend anything.
Most single-motor FAAC replacements are completed in 90 minutes to two and a half hours, including removal, installation, and setting limits and force to match the gate’s current travel. Underground operators run longer when the vault needs cleaning or re-bedding.
