FAAC Gate Motor Replacement Nationwide

FAAC Gate Motor Replacement: The Johns Creek Owner’s Guide

FAAC gate motor replacement in Johns Creek typically runs $1,150-$2,400 installed for a single residential swing or slide operator, depending on the 400-series model, arm geometry, and whether the existing mounting bracket is reusable. We stock FAAC-compatible drive assemblies and control boards on our trucks, and most replacements are completed in one visit. If your gate is moving slowly, stopping mid-travel, or not responding to the remote, the motor or its integrated gearbox is often the culprit.

Most Johns Creek homeowners notice the failure during the first cold snap of November or after a heavy rain season, when the sealed housing has already taken in moisture. The gate may jerk, hum without moving, or run in one direction only. These are not settings problems. They are mechanical failures inside the motor assembly.

Which FAAC Models This Applies To

We replace motors across the FAAC 400-series line most commonly found in Johns Creek residential installations: the 402 for light swing gates up to 800 pounds, the 422 for heavier single-leaf iron gates, and the 746 slide-gate operator used on longer driveway entries off Bell Road and the Medlock Bridge area. The 390 and 391 articulated arm models also appear on older properties with stone pillars where a linear actuator will not fit.

To identify your unit, check the silver data plate on the motor housing for the model number and manufacturing date. The 400-series uses a 24V DC motor with an integrated worm gearbox; the 746 uses a 230V AC reversible motor with external limit switches. These are not interchangeable. We also need to know your gate’s leaf width and weight, because FAAC rates operators by duty cycle and inertia, not just horsepower.

On OEM versus aftermarket: we install FAAC factory motors when the control board is still functional and the owner wants to preserve the original warranty alignment. For units over eight years old, we often recommend a quality aftermarket equivalent with a cast-aluminum gearbox housing rather than the original die-cast zinc, which corrodes faster in Georgia’s humidity. We quote both options in writing before ordering.

Signs Your FAAC Gate Motor Replacement Is Failing

• The gate hums but does not move. This usually means the motor is receiving power but the gearbox has stripped its worm gear or the thermal cutout has failed. The motor draws current without producing torque, which will eventually burn the windings.
• Movement is slow or uneven in one direction only. A failing armature winding or worn brush set creates asymmetric torque. On a FAAC 422, this often shows first on the closing cycle because that direction fights gravity and gate sag.
• The operator runs for a few cycles then stops for ten to thirty minutes. The internal thermal overload is tripping. In Johns Creek’s July heat, a motor already running near its limit will shut down faster. This is a precursor to complete winding failure.
• Grinding or clicking from the motor housing. The gearbox bearings are dry or the worm gear is chipped. FAAC gearboxes are factory-sealed and not serviceable; the entire motor-gearbox assembly must be replaced.
• Remote works but the gate does not respond, and the control board LED shows normal status. The motor is not drawing enough current to register a fault, but it is also not producing motion. We test this with an ammeter at the motor leads to confirm.

Replacement Cost & What’s Included

The total installed price depends on three things: whether the existing arm bracket bolts come free without drilling, whether the control board needs a firmware update to recognize the new motor, and whether we find secondary damage like a cracked chain sprocket or water in the conduit. We inspect all three before giving you the written price. Under Clause 1 of The Haven Standard, that price is the price. If we find something unexpected, we stop and call before proceeding.

Every FAAC motor replacement carries our 365-Day Done Right Promise. If the new motor hums, stalls, or fails to hold its limit settings within that year, we return and make it right at no charge. We also leave you a photo log of the installed part number, the amperage draw at full load, and the limit-switch positions we set.

DIY or Call Us?

There are two things a homeowner can safely check before calling: whether the manual release is fully re-engaged after a power outage, and whether the breaker feeding the operator is tripped. Both are visible without opening the housing.

Everything else requires caution. A FAAC operator stores energy in its gearbox and capacitor even when unplugged. The 400-series capacitor holds a 24V charge that can deliver a painful shock; the 746’s 230V terminal block is lethal if handled incorrectly. The motor itself weighs 18-34 pounds and mounts on a bracket that may be corroded through. We have replaced brackets that looked solid until the wrench applied torque and the bolt spun freely in crumbling aluminum.
