FAAC Gate Motor Replacement: The Santa Clarita Owner’s Guide
FAAC gate motor replacement in Santa Clarita typically runs $900 to $2,400 installed, depending on which FAAC model you have and whether the arm or piston bracket is still intact. We stock FAAC-compatible motors and hydraulic components on the truck for the most common 390, 400, 412, 750, and 770 series operators, and most replacements are completed in a single visit. You usually discover the motor has failed the hard way: the gate won’t open, or it opens halfway, groans, and stops, or the motor runs but the gate doesn’t move at all. By the time most Santa Clarita homeowners call us, the operator has been fighting a misaligned hinge or a sagging leaf for months, and the motor finally gave out doing work it was never sized for.
Key Takeaways:
- Installed FAAC motor replacement in Santa Clarita: $900 to $2,400, written before work starts
- We carry OEM FAAC motors and quality-compatible equivalents for 390/400/412/750/770 series operators
- Same-day or next-day replacement is standard for motors we stock; unusual models may take 2 to 3 business days for parts to arrive
- Every replacement includes a documented photo record of the install, per Clause 4 of The Haven Standard
- 365-Day Done Right Promise covers every FAAC motor replacement we perform
If your FAAC operator is dead or dying, call (747) 294-2900. A live person answers, any hour, and we can usually tell you over the phone whether we have your motor in stock.
Which FAAC Models This Applies To
FAAC builds two fundamentally different families of gate operators, and the replacement motor for one will not bolt into the other. The hydraulic 390, 400, 412, and 415 swing-gate operators, plus the 750 and 770 slide-gate series, use a dedicated motor-and-pump assembly. The newer 700, 770 Compact, and E124 electromechanical operators use a 24V DC gearmotor with a completely different mounting pattern and control-board integration. If you don’t know which family you have, open the plastic cover and look for the brass data plate. The model number is stamped there, typically in the format “FAAC 412” or “FAAC 750” followed by a serial number. Photograph that plate before you call anyone, including us. It saves a wasted trip.
For the hydraulic FAAC operators common in Santa Clarita, the single most confusing compatibility point is this: the 390 and 412 share a motor assembly, but the 400 uses a longer motor shaft, and the 415 runs a different displacement pump entirely. You cannot simply swap a 390 motor into a 400 housing without replacing the pump flange. We’ve seen this done, and the result is always the same: the coupler strips within six months and the gate dies again.
On the OEM-versus-aftermarket question, our position is specific. FAAC OEM motors are built to Italian spec and run reliably for years when the gate is balanced and the duty cycle is respected. Quality aftermarket equivalents exist for the 390/412 and 750 series, and we install them regularly at a lower parts cost. The key difference is not the motor windings; it’s the hydraulic shaft seal. Cheap aftermarket motors fail at the seal, and a leaky hydraulic motor leaks oil onto your driveway and kills the pump. If we install an aftermarket motor, it’s one with a viton seal and a known production date. If you’re replacing a hydraulic unit, ask any contractor whether the motor includes a new shaft seal. If they don’t know what that is, call someone else.
Vance Gate Repair Santa Clarita is an independent gate automation service provider. We are not affiliated with FAAC, and we service eight other automation brands, including LiftMaster, Mighty Mule, and Ghost Controls, so the recommendation you get is based on what’s already on your property, not on what we’d rather sell you.
Signs Your FAAC Gate Motor Replacement Is Failing

- The motor runs but the gate barely moves. On hydraulic FAAC units, this is the pump losing pressure or the shaft seal leaking fluid. The motor is still spinning; the hydraulic side has already failed. Ignore this and the motor burns out trying to build pressure that will never come.
- The gate opens fine but stalls halfway closed, then reverses. This is often mistaken for an obstruction setting, but on FAAC hydraulic operators it’s usually the motor overheating under load. The thermal overload is working exactly as designed. The gate is telling you the motor is undersized for the current hinge condition.
- A loud groan on startup that fades once the gate is moving. This is the motor pushing against a stiff gear or low hydraulic fluid. On electromechanical FAAC units, it’s typically a failing start capacitor. The capacitor is a $40 part. Running the motor on a bad capacitor for six months turns it into a $900 replacement.
- The gate stops at random positions and the control board flashes a fault light. The board is reacting to overcurrent, not a bad limit switch. In Santa Clarita’s summer heat, FAAC motors already run hot, and a dragging gate pushes them past their thermal ceiling. The motor is not dead yet, but it will be.
- You reset the breaker and the gate works for a day, then trips again. The motor’s windings are breaking down and drawing excess current. This is the point where continued use risks damage to the FAAC control board, which costs nearly as much to replace as the motor itself.
One thing we tell every Santa Clarita customer with a FAAC gate: the motor is almost never the first thing that fails. It’s the last thing. The hinge rusts, the leaf sags, the chain stretches, and the motor absorbs all of that extra load for years until it burns out. A replacement fixes the symptom. Unless we identify and correct what overloaded the original motor, the new one is on the same clock. We measure the amp draw at full travel, check the leaf for sag, and photograph the readings. You get that photo record before we leave.

AfterReplacement Cost & What’s Included
For FAAC motor replacement in Santa Clarita, here’s the pricing picture in plain numbers:
| Scope | Typical Santa Clarita Price |
|---|---|
| FAAC 390/412 hydraulic motor replacement, OEM | $1,100 to $1,600 installed |
| FAAC 390/412 hydraulic motor replacement, quality aftermarket | $900 to $1,250 installed |
| FAAC 750 slide-gate motor replacement, OEM | $1,400 to $1,900 installed |
| FAAC E124/electromechanical gearmotor replacement | $1,200 to $2,400 installed, depending on rail and bracket condition |
| Motor replacement plus hydraulic fluid flush and seal kit | Add $250 to $400 |
That price is the price. It’s written down and handed to you before we touch a tool, under Clause 1 of The Haven Standard. It includes the motor, the labor, any couplers and shaft seals the job needs, a full limit-switch re-set, pressure adjustment on hydraulic units, and a documented photo record of everything we found and installed. The 365-Day Done Right Promise covers the work: if the motor or our installation fails within a year, we make it right at no charge.
What drives the range is mostly the model and bracket condition. A clean 390 swap on a gate that’s still balanced is fast and straightforward. A 750 slide motor where the chain tensioner has seized and the rail is out of square takes real time. We’ll tell you which end of the range you’re on during the estimate, in writing, before anything is ordered or opened.
DIY or Call Us?

There are things you can safely check before calling anyone. Confirm the breaker hasn’t tripped. Confirm the release handle isn’t partially engaged. Look for obvious grease leaks at the bottom of a hydraulic operator. Listen for whether the motor hums or stays silent when you press open. Those observations help us diagnose faster.
What you should not attempt yourself is replacing the motor on any FAAC hydraulic operator. These are live electrical systems running on 120V or 240V, and the hydraulic pump holds residual pressure even with the gate fully closed. The motor shaft couples to the pump with a splined coupler under tension; getting it wrong means a damaged pump, a stripped coupler, or a control board destroyed by a miswired connection. We’ve repaired enough DIY FAAC replacements in Canyon Country and Valencia to know exactly what happens when the wiring diagram was skipped. Name what you found. Name what it costs. Name what you left behind. That’s the standard we work to, and if you’d rather not risk finding out what a failed DIY motor swap costs to un-do, call (747) 294-2900 and we’ll send a technician with the right parts and the right documentation.
FAQs
A properly installed FAAC hydraulic motor on a balanced gate typically lasts 8 to 12 years in Santa Clarita’s climate, sometimes longer. Electromechanical FAAC units run 6 to 10 years. The biggest factors are gate balance at installation, duty cycle, and whether the operator is sized for the gate’s actual weight and wind exposure. In the wind-prone areas near Sand Canyon and the upper Canyon Country neighborhoods, undersized motors on tall solid gates fail well short of their rated lifespan. Call (747) 294-2900 for an exact assessment of your gate and motor.
Sometimes. If the failure is a start capacitor, a shaft seal, or a pressure relief valve, we repair the existing motor and you’re billed for a part and service call, not a full replacement. On hydraulic units where the motor windings have burned or the pump has seized, rebuilding costs more than replacing and leaves you with an old motor’s remaining wear points. We’ll show you the readings and let the numbers decide. Estimates are free.
For the common 390 and 412 hydraulic motors that we stock on the truck, the swap takes about 2 to 3 hours from arrival to a fully tested, running gate. Slide-gate 750 replacements run 3 to 4 hours. Unusual models or electromechanical operators with bracket damage can stretch to a full day. We’ll give you a written time frame with the written price before work starts.
We keep OEM FAAC motors and quality aftermarket equivalents on the truck for the 390, 400, 412, 750, and 770 series, plus the common E124 gearmotor. If you have a less common FAAC model, we can usually source the correct motor from our Santa Clarita warehouse inventory or have it in hand within 2 to 3 business days. Call (747) 294-2900 with your model number and we’ll confirm stock before dispatch.
