Linear Gate Motor Replacement Nationwide

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

We stock, install, and program Linear-compatible gate motor replacements throughout San Antonio, and most residential swap jobs run between $650 and $1,450 installed, including the new motor, labor, and programming. If your Linear operator is dead, grinding, or opening halfway and reversing, we can usually have it replaced within one to two business days, often same day if the failure is a common model. You’ll know yours is going when the gate hesitates, growls on startup, or trips its own breaker more than once a month.

Most San Antonio homeowners discover the problem at the worst possible moment: the motor hums but nothing moves, or the gate starts opening and stalls. That’s the control board sending power but the motor no longer translating it into motion. The good news is a Linear gate motor replacement is a straightforward, predictable job when the technician knows the series and has the right part on the truck.

Which Linear Models This Applies To

Linear built its reputation on slide and swing gate operators that were workhorses for residential driveways and light commercial entries. The models we see most often in San Antonio are from the LRA, LSO, and older APeX series, along with the current PRO series operators. The specific motor head within each unit varies by swing versus slide configuration and by the weight rating of the gate it drives. That last point matters more than most owners realize: a motor spec’d for a 400-pound gate will fail early if it’s been pulling a 700-pound ornamental iron gate for five years.

Identifying your model is simpler than it sounds. Open the operator cover and look for the silver data plate. It will list the model number, serial number, voltage, and horsepower. Take a photo of that plate before you call us. It saves a return trip and lets us confirm we’re bringing the correct Linear gate motor replacement, not a close cousin. We carry OEM Linear motor heads and gear assemblies for current production models, and for older discontinued series we use tested, quality aftermarket equivalents that match the original mounting pattern and torque profile.

One compatibility gotcha worth knowing: Linear changed the mounting bolt pattern between the APeX and PRO series. A motor that looks nearly identical on the marketplace will not bolt up without modification. We’ve seen more than one San Antonio homeowner order the wrong part online and discover the mismatch after the old motor was already out.

We keep our most-requested Linear gate motor replacements stocked on the service trucks: LRA slide motors, LSO swing arm motors, and the common APeX replacement heads. If your model is unusual, we can typically source the part from our San Antonio supplier network within 24 to 48 hours.

Signs Your Linear Gate Motor Replacement Is Failing

• The motor hums but the gate doesn’t move. This usually means the start capacitor has died or the gear train has jammed. The motor is trying to spin but can’t translate that energy into motion.
• The gate stops mid-cycle and reverses. That’s the obstruction sensing circuit doing its job, but the real culprit is often a failing motor drawing more amps than the board expects. The board interprets the strain as an obstruction and reverses the gate.
• You hear a grinding or chattering noise on startup. The plastic drive gears inside many Linear operators are sacrificial by design. They wear before the motor does. If ignored, the stripped gear will eventually take the motor armature with it.
• The operator trips its breaker or GFCI repeatedly. A motor with shorted windings or worn brushes pulls excessive current. This is a fire hazard area, plain and simple, and should not be reset-and-ignore.
• The gate runs noticeably slower than it used to. A tired motor with worn bearings loses torque. You’ll notice it most on hot San Antonio afternoons when the thermal overload kicks in earlier.

If you catch a failing motor before it seizes, a replacement usually takes under two hours. If the motor has already seized and damaged the gear assembly, the job includes both the motor and the gear rebuild kit, which pushes the price toward the upper end of our range.

Replacement Cost & What’s Included

In San Antonio, a Linear gate motor replacement installed by us typically runs $650 to $1,450. The spread depends on three things: which series you have, whether the gear assembly also needs replacement, and whether your operator is a slide or swing configuration (swing arms often require more labor for alignment).

Your written price includes the motor or motor-and-gear assembly, removal of the old unit, installation, limit setting, force adjustment, and full cycle testing. We also verify the safety devices (photo eyes and edge sensors) still work correctly after the swap. The price we quote before starting is the price you pay. Every replacement carries our 365-Day Done Right Promise: if the repair fails within a year, we come back and make it right at no charge. That’s not a courtesy; it’s the deal.

Give us a call at (940) 531-3336. Tell us the model number off the data plate and what the gate is doing when it acts up. Cole Rafferty likes to say, “Tell me what it’s doing wrong – I’ll tell you what it costs to fix it, in writing, before we start.” We’ll have a tech at your San Antonio property with a name and photo sent to your phone before they arrive.

DIY or Call Us?

Here’s the honest split. You can safely check a few things before calling: confirm the operator has power at the outlet, listen for whether the motor hums or stays silent, and look at the data plate to write down the model number. That information genuinely helps us arrive with the right part.

What you should not do is open the operator and start removing the motor yourself. These units run on 120V or 240V line voltage, which can injure or kill. The motor connects to a gear assembly under spring tension in some models, and a wrong move there can send a sprocket or chain where you don’t want it. There’s a reason we recommend a trained professional for this repair, and it’s not to sell you a service call. The internal components of a Linear operator are not friendly to casual hands.

If you’ve already unbolted the operator cover and feel stuck, close it back up, kill power at the breaker, and call us at (940) 531-3336. We’ll walk you through what to check while the tech is on the way.
