FAAC Gate Motor Replacement Nationwide

FAAC Gate Motor Replacement: The North Miami Beach Owner’s Guide

A FAAC gate motor replacement in North Miami Beach typically runs between $1,400 and $2,800 installed, depending on whether you have a swing-arm (S-series or C-series) or sliding-gate (746/844) model and whether the control board survived the failure. We stock complete FAAC motor units, gearbox rebuild kits, and capacitor kits on the truck, so most replacements we complete same-day on the first visit. The way most North Miami Beach owners discover the part has failed is not dramatic: the gate starts moving slower over a few weeks, then one afternoon it hums for two seconds and stops, or the display on a 455D control board throws a “motor fault” and the gate will not respond to the remote. By the time we arrive, the windings are usually burnt or the capacitor has swollen to twice its normal size – and the salt air along Dumfoundling Bay is almost always a contributing factor.

Which FAAC Models This Applies To

We install and replace motors across the FAAC residential lineup that’s most common in North Miami Beach: the 402, 412, 415, and S418 swing-arm operators (often found on the double gates of gated communities along NE 20th Avenue and around Sans Souci Estates), plus the 746, 844, and 400 sliding-gate operators. If you have a 455D control board in the same enclosure, we can swap the motor independently without replacing the board – something that saves most owners $300 to $600 versus a bundled control package. The key identification step is simple: there’s a metal data plate on the motor body or the operator arm itself. Look for the model code and the “RPM” and wattage stamping. An S418, for example, is a 24V DC motor, while the older 402 is 115V AC – and mixing those up is the single most common reason a well-meaning DIY replacement ends with a burned board. We photograph that plate before we order or install anything, so there’s no guessing and no returned trips.

On OEM versus aftermarket: FAAC genuine motors carry a two-year manufacturer warranty and are built to tighter tolerances on the planetary gear interface. Quality aftermarket equivalents from companies like North Shore Commercial Gate or All-O-Matic’s rebranded line run 20-30% less and hold up fine on single-family gates in North Miami Beach, but we’ll level with you: if the gate cycles more than 15 times a day, spend the extra on OEM. The aftermarket units wear their brushes faster under that load. Either way, the price is written before we touch a tool.

Signs Your FAAC Gate Motor is Failing

• Gate moves slower than it did three months ago. The motor’s start capacitor is losing its ability to kick the arm into motion, or the gearbox oil has thickened with salt-air contamination. We see this constantly on properties within a mile of the Intracoastal.
• Humming sound for 1-2 seconds, then nothing. The motor is getting voltage but cannot turn – usually a seized gearbox or a swollen capacitor. If you keep pressing the remote after this, you’ll burn the windings and turn a $90 capacitor job into a full motor replacement.
• “Motor fault” or flashing indicator on the 455D board. The board is sensing an overcurrent condition from the motor. Sometimes it’s the motor; just as often it’s a failing limit switch forcing the motor past its travel and tripping the fault. We check both before quoting.
• Gate opens fine but stalls halfway through closing. On FAAC swing operators, this is frequently the thermal overload inside the motor tripping because the arm bracket has shifted and the motor is working against a misaligned pivot. The motor may still be good – but if it has been running like that for weeks, the windings are on borrowed time.
• Burning electrical smell near the operator box. That’s varnish burning off the motor windings. Stop using the gate immediately and kill the breaker. A motor that reaches this point is not repairable – it is a replacement.

Replacement Cost & What’s Included

In North Miami Beach, a FAAC swing-arm motor replacement (402, 412, 415, S418) runs $1,400-$2,200 installed, while FAAC slide-gate motors (746, 844, 400) land between $1,800 and $2,800 because the rack and pinion alignment adds a labor step. Here’s the flat structure we quote, in writing, before work starts:

Every quote includes the motor, installation, full travel-limit adjustment, force-setting recalibration, and safety-edge testing. The price is handed to you in writing before any work starts, and it does not change unless we find something you approve in advance. The replacement itself is covered by our 365-Day Done Right Promise: if it isn’t right within a year, we make it right at no charge. We are an independent service provider – not affiliated with FAAC – which is why we can be blunt about which parts last and which ones don’t in this climate.

DIY or Call Us?

A FAAC operator is not a tension-spring hazard the way a garage door is, but it is still a motorized gate – and the specific dangers on this part are two-fold. First, the motor runs on line voltage or 24V DC at high current, and opening the operator enclosure without killing the breaker can put you across a live terminal. Second, a gate that moves unexpectedly with the motor removed can crush fingers or a child – FAAC arms store energy in the gearbox even when unplugged. We don’t give step-by-step instructions for this replacement, because the mistake is never in the unscrewing; it’s in the limit-switch and force-setting afterward, where a gate set too fast becomes a weapon.

What you can safely do: listen for the hum or fault pattern, photograph the data plate, and kill the breaker so the gate stays put. Then call us. Adrian Vance has been running FAAC diagnoses across North Miami Beach for years, and the first thing he does is check what’s actually failed before quoting a motor at all – because sometimes the fix is a $120 capacitor, and we’d rather tell you that than sell you a motor you didn’t need. Call (754) 219-6080 and you’ll get a live person, 24 hours a day, and a written price before any work starts.
