FAAC Gate Motor Replacement: The Fort Worth Owner’s Guide

FAAC gate motor replacement in Fort Worth typically runs $850 to $1,400 installed, and we usually stock the common 400, 402, 415, and C720 parts in our truck so most swap-outs happen the same day we show up. What most owners notice first is a gate that grinds, stops mid-cycle, or makes a clicking sound without moving at all. Sometimes it’s a capacitor or limit switch giving up, and sometimes the motor itself has finally cooked.

If you’re reading this, odds are your FAAC operator gave you years of dependable service and now it’s dead in the closed position, or worse, stuck half-open with the Monday morning school run bearing down. That’s a lousy way to start the day. Let’s figure out what you actually need so you don’t buy parts you don’t, or pay for a whole new operator when one motor seals the deal.

Which FAAC Models This Applies To

If your gate swings, slides, or runs on a buried hydraulic operator, there’s a good chance it’s a FAAC underneath the cover. The models we see most in Fort Worth driveways are the 400 series swing operators (S418, S450H, 415, 412, 402), the 390 series undergrounds, and the hydraulic 770 and C720 slide models. The label on the side of the control box will tell you the model and date of manufacture, and the motor itself usually carries a stamped part number. Snap a photo of both before you call. It saves everyone time.

One thing about FAAC worth knowing: older 400 series motors are not interchangeable with the newer 415 and 412 lines without a compatible control board. FAAC changed the encoder and mounting patterns quietly, and if you’re shopping by “looks the same,” you can buy a motor that mechanically fits but won’t communicate with the board. That’s the kind of $200 mistake we’d rather you avoid. We keep OEM FAAC replacements alongside tested aftermarket units from the same Italian and Chinese suppliers most independent shops in Texas trust, and we’ll tell you plainly which is which on your invoice. We’re an independent Fort Worth shop, by the way, not a FAAC dealer, so our advice comes without a quota attached.

A useful Fort Worth specific tip: FAAC motors, especially the hydraulic C720 models, don’t love our July heat. The hydraulic oil thins, pressure drops, and the pump runs hotter and longer. The motor often outlasts the pressure seals, and replacing only the motor on a ten year old hydraulic unit can leave you with a fresh motor pumping through tired seals. We’ll test pressure before we quote that job so you don’t pay for half a repair.

Signs Your FAAC Gate Motor Replacement Is Failing

• Hum but no movement. The capacitor is usually the culprit here. Your motor is trying to start but can’t get the rotor turning. It’s a $15 to $40 part, but the hum also undersizes the problem: a seized gear or worn thrust bearing can create that same sound. We don’t fire the parts cannon; we meter the capacitor and check shaft rotation first.
• Gate stops halfway, then reverses. If your FAAC 400 series gate hits an invisible wall and backs up, the obstruction sensing is likely reading its own worn motor as resistance. Dirty limit switch contacts or a motor drawing high amps under load can both trigger the behavior. Older boards are also notoriously fussy about voltage drops, which our Texas grid seems happy to deliver in August.
• Loud grinding during travel. The drive gear on a FAAC worm screw wears in a visible pattern after 7 to 10 years, and when it slips, you hear it. Replacing just this gear is sometimes the right repair instead of a full motor swap. If you catch it early, the motor may survive. If you let it grind for months, metal shavings contaminate the gearbox and now you’re replacing the assembly.
• DC models beep and won’t move. FAAC 402 and 412 units run on battery backup, and the beep code on the control board is often the first warning. Low battery voltage tells the motor to stay still, but the motor isn’t necessarily dead. Sometimes it’s a failed transformer or charging relay upstream. We diagnose that before selling you a motor.
• Dead silence. If nothing at all happens, your FAAC motor may have burned a winding’s insulation, often after a storm surge or years of gate hinges getting so stiff the motor was working double. That’s the scenario where we inspect the gate’s own mechanical condition before dropping in a new motor. A new motor mounted to a gate that swings like a refrigerator door is a future warranty call waiting to happen.

Replacement Cost & What’s Included

For a FAAC swing gate motor replacement in Fort Worth, expect $850 to $1,400 installed. Slide and hydraulic operators like the 770 and C720 run toward the high end, sometimes a bit past it, because the motor and pump have to be removed as one unit and the system re-bled. The spread covers two things: which model you have, and whether we’re replacing one motor or rebuilding the drive assembly around it. We price the motor, labor, and any required hardware as separate line items on the written estimate.

A cheap aftermarket FAAC compatible motor will save you $150 to $250 upfront and may not reach its fifth birthday. An OEM motor costs more today and is what we suggest for anyone planning to stay in the house. Every gate motor replacement we do carries our 90-Day Done Right Promise in writing: if it’s not done right, we make it right. And like everything else, the price is agreed before we ever turn a wrench, never adjusted at the door. Call (817) 241-4067 and we’ll give you a straight number for your exact model.

DIY or Call Us?

You can safely check your breaker, verify the gate’s manual release moves freely, and confirm the battery terminals (on DC models) aren’t fuzzed with corrosion. Those checks cost nothing and give us a useful picture over the phone. Where DIY goes wrong is the moment you disconnect a FAAC motor’s capacitor. They hold charge even with power off, and the terminals bite. Anyone who’s grabbed one will tell you it’s not like a lawnmower spark plug; it’s an actual wallop.

Beyond the safety of it, the mechanical work is the unglamorous half. If the gate post shifted or the hinges are grabbing, your new motor will be dead inside three years and someone will blame the motor. That drives us crazy because we’ve seen it too many times, someone else’s motor on a gate that was never square to start with. We weld on site, we level the gate, we set the limits and leave with the gate closing on its own. If you want to save money, skip the motor swap and have us do the hinge maintenance. That’s honest advice from a shop that’s been at this since 2001.
