AfterFAAC Gate Motor Replacement: The Miami Beach Owner’s Guide
FAAC gate motor replacement in Miami Beach typically runs $1,150-$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 on our trucks and can usually complete the swap same-day if the gate structure and electrical feed are intact. Most Miami Beach owners realize their FAAC motor has failed when the gate stops mid-travel, reverses for no reason, or makes a grinding hum without moving the leaf.
Which FAAC Models This Applies To
FAAC has produced several series common in Miami Beach, and the motor you need depends on the operator family already bolted to your gate. The 400 series (412, 414, 415, 422) covers light residential swing gates up to about 800 pounds per leaf. The 770 series handles heavier residential and light commercial swing gates. For sliding gates, the 746 and 844 series are what we see most often south of Fifth Street and up through North Beach.
To identify your unit, check the silver data plate on the motor housing. You’ll find a model number, serial number, and production date. The mounting pattern matters too: 400-series arms use a different bracket spacing than 770-series units, and the 746 slider has a rack-compatible pinion that does not interchange with the 844. We carry both OEM FAAC motors and quality aftermarket equivalents from HySecurity and others. For gates exposed to salt air near the Atlantic or Biscayne Bay, we often recommend the aftermarket option with marine-grade sealing, since FAAC’s OEM gaskets tend to harden faster in coastal humidity.
One compatibility gotcha: early 400-series operators shipped with 115V motors, while later production switched to 230V. The housings look identical. Matching voltage wrong will either fry the new motor or leave it barely turning. We verify with a multimeter before ordering.
Signs Your FAAC Gate Motor Replacement Is Failing
- Gate stops partway open or closed. The motor brushes are worn to their limit, or the start capacitor has lost capacitance. In either case the motor stalls under load but may still run with no gate attached. We test stall torque against FAAC’s spec sheet to confirm.
- Loud grinding or squealing from the operator housing. The reduction gears inside the FAAC gearbox have lost lubrication or the nylon gear has stripped teeth. This happens faster in Miami Beach when water intrudes past cracked gaskets during summer storms.
- Gate reverses immediately after starting to move. The motor is drawing excessive amperage, which the control board reads as an obstruction. Sometimes it’s a binding gate, but if the mechanicals check free, the motor windings are shorting intermittently.
- Remote works but gate does not respond. The control board sends signal, the transformer outputs voltage, but the motor never energizes. Usually a failed thermal cutoff or seized armature. We see this on 400-series units past the eight-year mark in Florida heat.
- Visible rust weeping from the motor housing seams. Salt air has breached the casing. The motor may still run, but the bearings are degrading and the windings are next. On Alton Road properties we’ve replaced motors that looked fine internally six months prior.

AfterReplacement Cost & What’s Included
| Service | Price Range |
|---|---|
| Single swing gate motor (FAAC 400 series, installed) | $1,150 - $1,650 |
| Dual swing gate motor pair (FAAC 400 series, installed) | $1,850 - $2,400 |
| Heavy-duty swing motor (FAAC 770 series, installed) | $1,450 - $2,100 |
| Sliding gate operator (FAAC 746 or 844, installed) | $1,650 - $2,400 |
| Electrical troubleshooting if feed is suspect | $95 - $195 |
What drives the range: whether your existing mounting bracket and arm geometry are reusable, if the control board also took damage, and whether we need to rerun low-voltage wiring chewed by iguanas or corroded at the conduit. Every replacement includes removal and disposal of the old motor, installation and leveling of the new unit, limit-switch programming, safety-device testing, and a photographed record of all settings before we leave. The price we write down is the price you pay. Under Haven Standard Clause 1, no work starts until you have that written price in hand.
Our 365-Day Done Right Promise covers the full installation. If the motor fails or the gate drifts out of adjustment within that year, we make it right at no charge.
DIY or Call Us?
There is one safe thing an owner can check: verify that the breaker feeding the gate is on and that the manual release handle (usually a key-turn on FAAC operators) is fully re-engaged. Beyond that, gate motor replacement involves 110V or 230V electrical work, a 150+ pound operator that must be leveled to within a few degrees, and limit-switch settings that control crushing force. The springs inside a swing-gate arm are under tension even when the gate is open. We have seen homeowners drop operators on their foot or wire 230V motors to 115V feeds.
We are not affiliated with FAAC; we are an independent service provider. What we are is a company that arrives with the motor already in the truck, because Adrian Vance runs inventory tight and a second trip wastes your morning. Call (786) 371-2767 and we’ll confirm your model, quote the replacement in writing, and schedule the work.
FAQs
Seven to twelve years is typical, but coastal exposure shortens that. Motors within three blocks of the ocean often show internal corrosion by year five. We replaced a 414 on a Meridian Avenue property last year that looked perfect externally but had bearings locked with salt creep. Call (786) 371-2767 if your motor is past six years and acting up - estimates are free.
Sometimes. Brushes and capacitors are replaceable, and we carry those on the truck. But if the armature windings are shorted or the gearbox is stripped, rebuilding costs approach replacement and leaves you with old gaskets and bearings. We diagnose first, then recommend repair or replacement with the price for each option written out. Call (786) 371-2767 for a free second opinion on any other company’s estimate.
Most FAAC motor replacements take two to four hours. A straightforward 400-series swap with a reusable bracket is closer to two hours. If we need to fabricate a new mounting plate or rerun conduit, it extends toward four. We bring the part, the tools, and the documentation kit. You’ll have the photo log and written record before we leave.
We stock FAAC-compatible motors for the 400 series, 770 series, 746, and 844, plus the common arm assemblies and control boards. For discontinued models we can usually source within 24 hours. We also stock parts for LiftMaster, Mighty Mule, and Ghost Controls if your property has mixed brands. Call (786) 371-2767 and we’ll confirm we have your specific motor before dispatching.
We operate under The Haven Standard: written price before work starts, documented photo record on every visit, and the 365-Day Done Right Promise. Name what you found, name what it costs, name what you left behind. That’s how we work.
