FAAC Gate Motor Replacement: The West Hollywood Owner’s Guide
If your FAAC gate motor has quit or started grinding, we stock and install FAAC-compatible replacement motors for most residential models, with typical installed prices in West Hollywood running $850 to $1,900 depending on the series and what else got taken out with it. We carry the common 390, 400, and 770 series on the truck, so in most cases we can have your gate cycling again the same day we show up. How owners usually find us: the gate opens fine one afternoon, then the next morning it hums for three seconds, trips the breaker, or just sits there dead while the remote clicks uselessly. The motor board is often the first casualty, especially on hillside properties in West Hollywood where the gate fights gravity every single cycle.
Which FAAC Models This Applies To
We work on the FAAC 390, 391, 400, 412, 415, 422, 750, 760, and 770 series, plus the 844 and S800 for slide gates. The quickest way to identify yours is the silver data plate on the motor housing or the control board cover. It will list the model and the hydraulic or electromechanical designation, and that matters because a 390 motor will not bolt into a 400 swing gate operator without adapter work. One compatibility gotcha we see often in West Hollywood: the FAAC 422 and 770 share the same controller board but not the same pump, so if the board fried and took the pump with it, you need the pump matched to your exact series, not just a board swap. FAAC uses proprietary Molex connectors on many of its harnesses, so a generic aftermarket motor from a big-box store will not plug in without cutting and splicing, which voids the warranty and usually leaks or shorts within a year. For FAAC specifically, we recommend OEM motors or known aftermarket equivalents that mirror the FAAC mounting pattern and hydraulic flow rate. Gatewood Fence & Gate is an independent service provider, not affiliated with FAAC, which means we are free to tell you when a motor is genuinely repairable instead of always reaching for a replacement box.
Signs Your FAAC Gate Motor Is Failing
- The motor hums but the gate doesn’t move. On hydraulic FAAC units this usually means the pump is trying but the hydraulic fluid has leaked out or the internal bypass is stuck. The motor itself may be fine, but it is working against nothing, and that will burn it out within a few weeks.
- The gate opens halfway and stops, or reverses for no reason. This often traces to a failing capacitor or a worn motor bearing that is tripping the obstruction sensing. On FAAC boards the red diagnostic LED will flash a fault code during the failure, and that code tells us whether it is the motor or the safety circuit.
- You smell hot oil or electrical insulation after a cycle. FAAC hydraulic motors run hot when the fluid is low or the pump is cavitating. If you catch this early, a seal kit and fluid change might save the motor. If you wait until the gate stops moving, the motor is usually done.
- The gate moves slower in one direction, or labors going uphill. On swing gates mounted on West Hollywood hillside driveways, the motor is constantly fighting gravity. A motor that has been overloaded for years will start dragging before it fails outright, and that dragging strain is what kills the controller board next.
- The breaker trips every time the gate runs. That is the motor drawing more current than it should, either from internal winding wear or from the gate itself binding and forcing the motor to work too hard. We always check the hinge posts and wheel track before condemning a motor, because a gate that is binding will kill a brand new motor the same way it killed the old one.
Replacement Cost & What’s Included
In West Hollywood you can expect to pay $850 to $1,900 installed for a FAAC gate motor replacement, depending on whether we are swapping a 390 hydraulic swing motor or a heavier 844 slide gate operator, and whether the controller board and safety edges survived the failure. The parts range from roughly $400 to $1,100 for the motor itself, and the labor is the difference. Every quote we give is the price, and the price is agreed before any work starts, so there is no invoice surprise at the end. The installation includes removing the old motor, mounting and aligning the new one, refilling and bleeding the hydraulic system if applicable, wiring the safety edges and photocells back in, and cycling the gate at least six times to confirm clean operation. Every replacement carries our 90-Day Done Right Promise in writing. If it is not done right, we make it right, one call and Hal is back out.
DIY or Call Us?
You can safely check a few things: whether the breaker is tripped, whether the remote battery is dead, and whether the gate has visible debris blocking the track or bottom edge. What you should not do is open the FAAC motor housing and start probing wires. These motors run on 120V or 240V line voltage, the hydraulic units hold pressure even when unplugged, and the capacitor can hold a charge that will knock you on the ground. We have seen owners replace a board themselves, wire the harness one pin off, and fry a brand new $500 board in twenty seconds. If the gate is heavy and you are standing on a slope, do not unbolt the motor from the mount unless you know exactly how you are going to hold the gate still. Call (323) 677-4063 and tell us what the gate is doing wrong. Hal will give you a straight answer over the phone, and if it needs a motor, the price will not change when we get there.
FAQs
Expect 8 to 12 years for a residential FAAC motor in West Hollywood, but hillside swing gates that cycle frequently and fight gravity can wear one out in 6 to 8 years. The controller board usually fails before the motor itself, especially if the gate has been overloaded, so sometimes the motor is fine and the board is the real culprit. If your FAAC is over 10 years old and the motor has failed, replacing both the motor and board together is the smarter long-term move. Call (323) 677-4063 and Hal will tell you honestly whether that is your situation before any work is scheduled.
Yes, in many cases a FAAC motor can be repaired instead of replaced, particularly if the failure is a seal leak, a bad capacitor, or a worn bearing. On hydraulic units a seal kit and fluid change runs far less than a full motor replacement, and we do that repair on site in your driveway. If the motor windings have burned or the pump housing is cracked, replacement is the honest call. Tell Hal what the gate is doing wrong and he will tell you what it actually needs, and if the estimate says repair, that is what you get.
Most FAAC gate motor replacements in West Hollywood take 2 to 4 hours on site, including removal, mounting, wiring, hydraulic bleed, and full-cycle testing. We carry the common 390, 400, and 770 series motors on the truck, so the swap can often be completed the same day we arrive. If we have to special-order a less common model or matching controller board, we will tell you the lead time before we schedule the return visit. Call (323) 677-4063 with your model number ready and Hal can usually tell you over the phone whether the part is on the truck.
We stock FAAC-compatible replacement motors for the 390, 400, 770, and 844 series, plus controller boards, safety edges, photocells, and hydraulic fluid kits, and we also carry parts for LiftMaster, Mighty Mule, and Ghost Controls on the truck. If we do not have your exact motor in the van, we can usually have it in hand within 2 to 3 business days. Tell me what it’s doing wrong and I’ll tell you what it actually needs, give me your number and I’ll call you back myself. Call (323) 677-4063 and ask for Hal.
