Linear Gate Motor Replacement Nationwide

Linear Gate Motor Replacement: The San Antonio Owner’s Guide

A Linear gate motor replacement in San Antonio typically runs between $425 and $1,150 installed, depending on the specific Linear model and whether you need a full operator swap or just the motor assembly. We stock Linear-compatible replacement motors on our service trucks and can usually complete the swap the same day we diagnose it.

Most San Antonio homeowners don’t wake up thinking about gate motors. They notice the gate started moving slower, or it stopped halfway last Tuesday, or the remote works only when you’re close enough to touch the gate. Then one morning it just hums and doesn’t move at all. That’s the moment you’re on this page, and that’s the exact problem we fix.

Which Linear Models This Applies To

Linear is one of the most common gate opener brands we pull out of San Antonio driveways, and not all Linear motors interchange. The two big families we work with are the Linear LRA swing gate series and the Linear SLR slide gate series. The LRA models (you’ll see LRA500, LRA1000, LRA2000 on the motor label) use an articulating arm setup common on ornamental iron gates around Terrell Hills and Monte Vista. The SLR slide operators sit in concrete pads along the fence line, and those show up on wider residential lots in Stone Oak and along Schertz Road.

The compatibility gotcha: Linear changed motor mounting footprints between older LRA and newer LRA-EX versions. A motor that bolts into a 2010 LRA1000 will not drop into an LRA1000EX without the adapter plate, which adds about $60 in parts. We match by the silver data plate on the side of the operator, not by the remote or the keypad. Take a photo of that plate before you call, and Nico Alvarez can usually tell you over the phone whether we carry the exact match.

On OEM versus aftermarket: for Linear specifically, we stock both genuine Linear replacement motors and a quality aftermarket equivalent that carries a comparable 12-month parts warranty. The aftermarket option saves you 20 to 30 percent, and we stand behind it the same way. If you’d rather keep the operator all-Linear, the OEM route is available and we quote it as a separate line item.

Signs Your Linear Gate Motor Needs Replacement

• The motor hums but the gate doesn’t move. This is the classic failed capacitor or stripped gear, but on Linear units we’ve seen the motor windings themselves burn out after years of Texas heat. A hum with no movement usually means the motor is trying and failing.
• The gate opens halfway and stops. The thermal overload inside the motor is tripping because the motor is pulling too much current. In San Antonio summers, we see this pattern spike in July and August when the motor’s been baking in a metal housing all afternoon.
• The gate moves slower every week. This is a motor losing torque. By the time you notice it, the brushes inside the motor are usually worn down, and a new motor is more cost-effective than a rebuild.
• You have to press the remote multiple times. The issue can be the radio receiver, but if you hear the click and the motor still won’t engage, the culprit is often internal. We test the board and the motor separately before quoting anything.
• The gate reopens or reverses on its own. This points to a failing motor drawing irregular current, which trips the obstruction sensing. It’s the gate’s way of saying the motor can’t push reliably anymore.

Replacement Cost & What’s Included

For a Linear residential gate motor replacement in San Antonio, you’re looking at $425 to $1,150 installed. The spread comes down to three things: whether it’s a swing or slide model, whether you need the articulating arm assembly as well, and whether we go OEM Linear or the quality aftermarket equivalent.

Every quote includes removal of the old motor, installation, wiring, limit adjustment, and a full function test before we leave. The labor is quoted separately from the part so you see exactly what you’re paying for. And like every job Calder Gate Repair does, the price is written down and agreed before we start. If the invoice ever matched anything other than the quote, the quote wins.

DIY or Call Us?

You can safely check a few things before calling: confirm the operator has power at the outlet, check that the manual release lever isn’t stuck in the disengaged position, and look for obvious damage to the arm or chain. That’s about where the safe DIY zone ends on a Linear operator.

These motors run on 120V with an internal capacitor that holds a charge even after the unit is unplugged. The motor swap also involves re-setting the limit switches, which on Linear swing arms means the gate’s travel arc has to be re-learned precisely or the gate will slam into the post or a car. We’ve fixed enough DIY attempts where a homeowner’s new motor was installed but the limits were set wrong and the gate bent its own hinges. If you’re not comfortable discharging the capacitor and verifying the wiring against the Linear schematic, call us at (361) 314-4803. We’ll give you an honest recommendation, and if a repair makes more sense than a full motor swap, we’ll tell you that too.
