FAAC Gate Motor Replacement Nationwide

FAAC Gate Motor Replacement: The Roswell Owner’s Guide

Most FAAC gate motor replacements in Roswell run between $1,180 and $2,400 installed, depending on whether you need a single swing arm, dual swing arms, or a sliding gate operator. We stock FAAC-compatible motors and mounting hardware on our vans and can typically complete the swap same-day if we have your model details when you call. The failure usually announces itself gradually: the gate starts hesitating on cold mornings, then stops mid-travel, then won’t move at all until you cycle the power.

Which FAAC Models This Applies To

FAAC operators fall into distinct series, and the replacement motor must match both the mechanical format and the control board’s voltage profile. We regularly replace units in the 400 series (the compact 402 and 422 swing-arm operators common on residential driveway gates around Roswell’s historic district), the 700 series (heavier 746 and 844 units for estate gates), and the 720/721 sliding gate operators found on many Alpharetta Highway commercial properties.

To identify your motor, check the silver FAAC label on the operator housing for the model number and production date code. The arm length matters: a 402 with a 270mm stroke cannot accept a 350mm replacement without bracket modification. We carry both OEM FAAC motors and quality aftermarket equivalents from HySecurity and US Automatic. For Roswell’s humidity cycles, we typically recommend OEM on units under ten years old because the factory sealing around the gearbox holds up better to the mold and pollen load we see from April through October.

Signs Your FAAC Gate Motor Replacement Is Failing

• The gate reverses before reaching the limit. The internal encoder or mechanical limit switch is sending erratic position data, often caused by moisture infiltration into the motor housing after years of Georgia rain cycling.
• Audible grinding with slow or no movement. The worm gear inside the reduction box has stripped or the bronze bushing has worn oval, a failure mode we see frequently on FAAC 746 units that have been opening 400-pound wood gates since the mid-2000s.
• Operator runs but the arm doesn’t extend or retract. The clutch mechanism has failed or the internal shear pin has broken, which protects the gearbox from damage but renders the gate inoperable until the motor is opened and rebuilt or replaced.
• Intermittent response to remote or keypad commands. The motor’s internal capacitor is failing, causing insufficient startup torque; this often worsens in Roswell’s summer heat when capacitor electrolyte degrades faster.
• Visible oil leakage from the motor housing. The shaft seal has failed, allowing gearbox lubricant to escape and water to enter; continued operation without replacement will destroy the control board mounted directly below.

Replacement Cost & What’s Included

What moves the price: whether the existing mounting bracket is salvageable, if the control board also took damage from the motor failure, and whether the gate itself needs rebalancing before the new operator can be calibrated correctly. We deliver a written price before any work starts under Haven Standard Clause 1, and that price includes the 365-Day Done Right Promise. Every replacement leaves with a photo log of the wiring connections, limit switch settings, and the installed part number.

DIY or Call Us?

There is safe triage and there is work that belongs on a truck with the right tools.

What you can check: verify the breaker hasn’t tripped, confirm the photo-eye LEDs are aligned (the red or green indicator on the receiver eye), and test whether the gate moves freely by hand with the operator disengaged using the manual release key. If the gate binds manually, the problem may be mechanical, not the motor.

What we do not recommend: removing a 35-pound operator arm under spring tension, working on 120V control wiring without lockout verification, or attempting to recalibrate FAAC limit switches without the manufacturer’s programming tool. The stored energy in a swing-gate arm can cause serious hand or facial injury if released improperly. We carry the specific FAAC programming cable and have the torque-limited tools to set clutch pressure without stripping the adjustment screw, which is a common DIY error that converts a motor replacement into a full bracket rebuild.

Call (706) 928-9815 and we’ll walk through the symptoms by phone. If it sounds like a motor failure, we’ll confirm the model from your label photo and bring the right unit.
