FAAC gate motor replacement in San Jose typically runs $780 – $1,420 installed, depending on the specific FAAC series, the actuator style, and whether your control board needs attention at the same time. Most swing-gate actuator swaps take us 1.5 – 3 hours on site, and we stock common FAAC-compatible motors and parts on the truck. The way owners usually discover this problem: the gate makes a grinding hum but won’t budge, or it starts opening halfway and reversing, and eventually the motor just quits under load.
If that sounds familiar, you’re in the right place. Below we cover exactly which FAAC models this applies to, what fails first, what a replacement honestly costs in San Jose, and the one thing you should never attempt yourself.
Key Takeaways
- Installed FAAC gate motor replacement in San Jose: $780 – $1,420 parts and labor.
- We stock FAAC-compatible motors plus hydraulic pump units on our service trucks.
- Most replacements are done same-visit; we quote the price in writing before any work starts.
- The 365-Day Done Right Promise covers the replacement motor and the labor.
Which FAAC Models This Applies To
We work on the FAAC swing-gate actuator lines most common in San Jose residential driveways: the 400 Series (the 402, 412, 422 operator arms), the 750 and 770 underground series, and the older 390 and S418 models that still run plenty of gates in the Almaden Valley and Willow Glen. The key to matching a replacement motor is reading the label on the operator housing, not guessing from the gate’s appearance. FAAC stamps model and serial numbers on a metal plate riveted to the actuator body or the pump housing. You’re looking for a code like 402 CBAC or a 750 series designation followed by a production year.
Here’s a compatibility gotcha we run into regularly: a FAAC 400-series motor is not interchangeable with a 390 motor, even though the housings look similar from the outside. The mounting bolt pattern, the shaft length, and the encoder wiring all differ. Owners sometimes buy a used motor online, bolt it up, and then call us to sort out why the gate slams at the end of travel. On the OEM-versus-aftermarket question: for FAAC specifically, we lean OEM or a known-quality equivalent like a rebuilt hydraulic pump from a supplier with a verifiable track record. The hydraulic 750 and 770 series are particularly picky about seal tolerances, and a cheap aftermarket pump that weeps oil inside the housing will ruin a fresh motor in a few months.
Portcullis Gate Repair San Jose is an independent gate service company. We are not affiliated with FAAC, which honestly works in your favor, because we’ll tell you when a rebuild makes more sense than a brand-new motor.

Signs Your FAAC Gate Motor Replacement Is Failing
Most FAAC failures give you warning signs for weeks before the gate stops completely. Here’s what we hear about most often on service calls in San Jose, and what each symptom points to.
- Gate hums but doesn’t move. The motor is getting power but the hydraulic pump isn’t building pressure. In the 750 series, this typically means the pump seals have worn out or the hydraulic fluid has leaked past the piston. The motor still spins; it just has nothing to push against.
- Gate slows down noticeably over a few weeks. On FAAC’s hydraulic operators, cold oil in the San Jose morning makes every gate move a little slower, but if it stays slow at noon on a 65-degree day, the motor or pump is losing efficiency. You’re feeling reduced torque before the failure gets loud.
- Intermittent operation, particularly after rain. Moisture works into the actuator housing seals and grounds out the motor windings or the limit switch wiring. San Jose’s wet winters and heavy morning dew in the hills make this seasonally predictable.
- Gate opens partway, then reverses or stops. This often looks like a control board problem, but on FAAC swing gates it’s frequently the motor’s internal encoder failing to report position accurately. The board kills the run for safety because it doesn’t know where the gate actually is.
- Burning electrical smell near the operator. That’s a motor running too hot, usually because a failing bearing or a pump with hydraulic restriction is making it work double. This is the one to take seriously immediately; a cooked motor can damage the control board when it finally shorts.
Replacement Cost & What’s Included
Here’s the honest range for FAAC gate motor replacement in San Jose, quoted the same way we’d write it on an invoice.
- 400 Series operator arm motor (402, 412, 422): $780 – $1,150 installed.
- 750 / 770 underground hydraulic pump and motor assembly: $1,050 – $1,420 installed.
- 390 / S418 legacy swing arm motor: $850 – $1,150 installed, with a note that some 390 parts now require a retrofit plate because FAAC discontinued certain mounting brackets.
- Control board replacement if the failed motor took it out: add $260 – $480.
The range depends on what we find: the model series, whether the mounting hardware is corroded into place, and whether the limit switches and wiring are reusable. You get the price in writing before any work starts, and that’s the price on the invoice when we finish. No “well, it turns out the teardown was more complicated” additions. The replacement motor itself carries our 365-Day Done Right Promise: if it fails inside a year, we come back and make it right at no charge, and the return visit is free.
That’s the Kingswell Way on every job: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails.

What you can safely check yourself: the breaker or disconnect at the control box, obvious physical damage to the arm or linkage, and whether the gate swings freely by hand when you pull the release. If the gate itself is binding, that’s useful information; a motor replacement won’t fix a hinge or wheel problem that’s been overloading the operator for a year.
What you should not attempt: opening a FAAC hydraulic cylinder or the underground 750/770 pump housing. These units hold hydraulic fluid under pressure, and a seal failure during disassembly can spray oil with enough force to hurt someone. Same goes for the electrical side: FAAC operators run on line voltage with a capacitor inside that holds a charge even after the breaker is off. A charged capacitor can bite. If you’ve confirmed power is reaching the operator and the gate still won’t move, that’s the moment to call us at (669) 800-5686. We’ll give you the honest range over the phone and quote the exact number before any work starts.
FAQs
A well-maintained FAAC actuator typically lasts 8 – 12 years in San Jose’s climate, with underground 750/770 series units often going longer because the housing sits below grade and avoids direct sun and rain exposure. The 400 Series arm motors tend to fail sooner on gates without proper end-stop adjustment, because the motor keeps pushing against the stop long after the gate has closed, and that fighting against the stop is what kills the windings eventually. If you’re replacing a motor before year six, ask us to check the stop settings before we leave.
Sometimes, yes. On the 400 Series, a motor with good windings but failed seals or a worn gear can often be rebuilt with a seal and bearing kit for $220 – $380 in labor and parts, and we’ll tell you if that’s the better call before quoting a full replacement. On the 750/770 underground series, a hydraulic pump rebuild is occasionally a smarter money decision than a new assembly, but if the motor itself has burned windings, replacement is the honest answer. Call (669) 800-5686 and Dean Prescott can tell you which path fits your specific symptom.
Most 400 Series arm motor swaps on a standard San Jose driveway gate take 1.5 to 3 hours on site. Underground 750/770 pump replacements run longer, usually 3 – 5 hours, because we’re working below grade and have to pull the gate leaf off or block it safely while the unit is out. We’ll give you the window before we roll, not after.
We stock common FAAC-compatible motors, hydraulic pump assemblies, seals, and control board capacitors on the truck, so a lot of San Jose replacements are done the same day. For less common legacy series like the 390, we may need to order a part from our Sacramento supplier, which usually lands in one to two business days. Call (669) 800-5686 with your model number and we can tell you which one yours is before the truck leaves the yard.
Yes. Beyond FAAC, we carry parts and run service for LiftMaster, Mighty Mule, Ghost Controls, BFT, Linear, Viking, DoorKing, and Elite. If you have a mixed property, a FAAC swing gate at the driveway and a LiftMaster slide operator at the back, one truck handles both. We’re an independent shop, not tied to any single manufacturer, so the recommendation comes from what your gate actually needs, not what we’re obligated to sell.
