FAAC Gate Motor Replacement in San Jose, CA

FAAC Gate Motor Replacement: The San Jose Owner’s Guide

A complete FAAC gate motor replacement in San Jose typically runs $1,200 to $2,400 installed, depending on the model series and whether your gate is single or dual swing. Most replacements we handle are completed in one visit, and we stock FAAC-compatible drive units for the common 400 and 700 series on our service trucks. If your gate has stopped mid-travel, reverses for no reason, or the motor hums without moving the gate, the drive unit is usually the culprit.

We see this failure pattern often in San Jose’s older neighborhoods like Willow Glen and Almaden Valley, where FAAC systems installed in the 2000s are reaching their natural end of life. The combination of our dry summers and occasional winter moisture cycling through the housing wears down the brushes and armature faster than the spec sheet suggests.

Which FAAC Models This Applies To

FAAC organizes its residential and light-commercial gate motors into series families, and matching the correct replacement means reading the data plate carefully. The 400 series covers most single-family swing gates in San Jose, including the 402, 422, and 452 models, with torque ratings from 250 ft-lbs up to 1,100 ft-lbs. The 700 series handles heavier dual-swing and estate gates, with the 746 and 844 being the units we replace most often in the foothill properties off Sierra Road and around Silver Creek.

To identify your unit, look for the metal data plate on the motor housing, not the plastic cover. You’ll need the model number, production year, and the voltage spec, 115V or 230V. A common gotcha: the 400 series and 700 series use different mounting bolt patterns, and the control board pinouts changed in 2011, so a newer motor will not handshake with an older board without an adapter harness.

We carry both OEM FAAC motors and quality aftermarket equivalents from HySecurity and US Automatic where the application allows. For most San Jose residential jobs, the aftermarket unit matches the OEM spec at a lower parts cost, and we warranty the work identically either way. For commercial properties with high-cycle use, we typically recommend staying with the FAAC factory unit.

Ironworks Gate Co. of San Jose is an independent service provider. We are not affiliated with FAAC, but our technicians are trained and equipped to service their full product line.

Signs Your FAAC Gate Motor Replacement Is Failing

• The motor hums or clicks, but the gate does not move. This usually means the armature is spinning inside a stripped gearbox, or the start capacitor has failed. In either case, the motor draws power without transferring torque, and continuing to cycle it will burn out the windings entirely.
• The gate moves slowly or stalls on slight grades. FAAC motors have internal thermal cutouts that degrade with age. When the motor overheats, it drops into a reduced-power mode. We see this especially on uphill swing gates in the hilly terrain around Evergreen and East San Jose.
• Intermittent operation, fine one day and dead the next. Moisture intrusion through worn shaft seals causes corrosion on the control board contacts. San Jose’s morning fog in the spring and fall accelerates this, and by the time the owner notices, the board and motor often both need attention.
• The gate reverses immediately after starting to open. This can look like a safety sensor issue, but a failing FAAC motor with weak torque output will trigger the force-sensing algorithm to reverse the gate as a protective measure. Testing with a calibrated force gauge separates a motor problem from a sensor problem.
• Burning smell or visible scorching on the housing. The motor windings are shorting to ground, usually from water damage or age-related insulation breakdown. This is a fire risk, and the unit should be disconnected at the breaker until a technician evaluates it.

Replacement Cost & What’s Included

What drives the range: single swing vs. dual swing, the series and torque rating, whether the existing control board is compatible, and access conditions. A straightforward 402 replacement on a level driveway in Cambrian Park is at the lower end. A dual 746 on a steep grade in the Los Gatos hills, with a 2010 control board that needs adapting, runs higher.

Our pricing is settled before we start, no surprises on the bill. Every replacement carries our 90-Day Done Right Promise, the Keystone Standard, written and with no paperwork to chase down. If it is not right, we come back and make it right.

Active offers: $50 off any repair over $250, free second opinion on any written estimate, and a permanent 5% senior and veteran discount.

DIY or Call Us?

There is a safe middle ground here. A homeowner can verify the data plate model number, check that the breaker is live, and confirm the manual release works. These three checks save time when you call and rule out the obvious.

What we do not recommend: removing the motor housing, attempting to rebuild the gearbox, or working on the 115V or 230V electrical connections. FAAC motors are heavy, the capacitors hold a lethal charge even when disconnected, and the spring-loaded manual release can catch a finger. We have been called to jobs in San Jose where a well-intentioned owner turned a $1,400 motor replacement into a $2,800 job by damaging the control board and bending the gate arm.

If it rolls or swings, we get it working right, and we tell you exactly what we did. A quick call to (866) 977-5773 gets a live person, 24 hours a day, and we can usually have a technician out same day or next.
