FAAC Gate Motor Replacement Nationwide

FAAC Gate Motor Replacement: The Long Beach Owner’s Guide

FAAC gate motor replacement in Long Beach typically costs $850 to $1,450 installed, depending on which FAAC series you have and whether the arm bracket survived the failure. We stock FAAC-compatible replacement motors on the truck and can usually have your gate running the same day we diagnose it. Most Long Beach owners discover the problem the same way: the gate starts moving slower than it used to, then one morning it opens halfway and stops, or it hums without moving at all. The motor didn’t fail overnight. It wore down a little at a time, often for months, and the symptoms were hiding in plain sight.

Which FAAC Models This Applies To

FAAC has been building gate operators for decades, and the replacement path depends on which series is on your property. The 390 and 391 swing-arm operators are the most common residential units we replace in Long Beach, along with the 750, 760, and 770 series sliding-gate motors. The newer C720 and S450H series show up on homes built after 2015. Each series uses a different motor assembly, and the mounting bolt pattern is not interchangeable between a 390 and an S450H. Before you order anything, find the label on the housing and write down the model number and year code. If the label is worn off or painted over, we can identify the series from the arm profile and the capacitor size during a service call.

On the OEM-or-aftermarket question, we’ve replaced enough FAAC motors to have a firm opinion. FAAC’s OEM motors are well built, but the aftermarket equivalents for the 390 and 750 series are often produced by the same contract manufacturers and carry the same torque and RPM ratings. The cost difference is usually $120 to $200. We will install either one, and we’ll show you the exact motor going in before we bolt it down, with the part number on your invoice. The compatibility gotcha on older FAAC units: the capacitor required for a 390 series is 12.5 microfarads, but the C720 uses a 14 microfarad cap. Installing a motor with the wrong cap will run the unit hot in a month. We check this every time.

Signs Your FAAC Gate Motor Replacement Is Failing

• The gate moves noticeably slower than it used to. The motor’s run capacitor is losing its ability to hold a charge, which means the motor is working harder just to produce the same movement. A slow gate puts extra load on the gears and shortens whatever life the motor has left.
• The motor hums but the gate doesn’t move. The start circuit has failed or the capacitor is completely dead. The hum is the motor trying to start and failing. Continuing to hold the button down or trigger the remote while it hums will burn out the windings in under a minute.
• The gate stops mid-travel and goes into alarm or fault mode. This usually means the motor is overheating and tripping the thermal cutoff. In Long Beach’s coastal neighborhoods near the Colorado Lagoon, salt air accelerates corrosion on the circuit board connections, which can mimic motor failure when the real problem is a corroded terminal.
• Oil or grease leaking from the gearbox onto the mounting plate. The output shaft seal has failed, and the gear oil is leaking out. This is not repairable on most FAAC residential units. Once that seal goes, the gearbox runs dry, and the motor burns out shortly after.
• The gate starts and stops hard, with a shudder at the beginning of travel. The motor bearings are worn, which shows up as visible vibration on the arm. The motor is still running, but the bearings are grinding, and replacement now means saving the gearbox and arm bracket instead of replacing everything.

Replacement Cost & What’s Included

In Long Beach, a FAAC gate motor replacement runs $850 to $1,450 installed, and the price depends on three things: which series you have, whether the arm bracket and manual release are still sound, and whether the control board survived the failure. A basic 390-series motor swap with the existing arm bracket intact typically lands around $850 to $1,050. An S450H or C720 replacement with a new arm, capacitor, and limit-switch reset runs $1,150 to $1,450. The number we quote is the number you pay. You get a written price before any work starts, which means the motor, the labor, the capacitor if needed, and any new hardware all appear on the paper in front of you before we open the housing.

Some checks are safe for an owner to make: confirm the breaker is on, check the manual release lever isn’t half-engaged, and look for visible corrosion on the circuit board terminals. If the motor hums, stop there. A FAAC gate motor runs on 115V or 230V AC, and the capacitor stores enough of a charge to hurt you even with the power off. We have had to replace more than one motor where an owner opened the housing, tested a live connection, and damaged the board in the process. If your gate is on a hillside or slope, the under-gate force required to hold the leaf is higher, and the motor is not a beginner’s swap. The motor mount bolts are torqued to spec, not snugged, and the limit switches must be set exactly. Call us at (424) 788-1027 and we’ll come look. The diagnostic visit is free, and you get a written price before we touch anything.
