Linear Gate Motor Replacement Nationwide

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

If your Linear gate motor has stopped responding, hums without moving the gate, or trips its breaker every time it runs, the operator has likely reached the end of its service life. Replacing a Linear gate motor in San Antonio typically costs between $1,100 and $2,600 installed depending on the arm type, gate weight, and whether you need a swing or slide operator. We stock replacement Linear operators and compatible parts on our trucks, and we can usually have your gate working again the same day we diagnose it.

Most San Antonio homeowners discover the motor has failed in one of two ways: the gate simply won’t open one morning, or it opens halfway and reverses. Occasionally a motor that’s been running for years starts sounding wrong first, a grinding or clicking that wasn’t there before. Whatever the first sign was, a Linear operator that’s failed mechanically rarely makes sense to rebuild. Swapping in a new motor, matched to the gate’s weight and duty cycle, is usually the faster and more honest fix.

Which Linear Models This Applies To

Linear made two main families of gate operators that we still see throughout San Antonio neighborhoods: the swing-arm operators (like the ACT 33 and ACT 34 series) and the slide-gate operators (like the SL series). The ACT 33 handles single swing gates up to about 16 feet and 600 pounds. The ACT 34 is built for heavier single swing gates or paired gates where two operators run in master-and-slave configuration. The SL slide operators cover rolling and cantilever gates, with the SLD model handling residential slide gates up to roughly 40 feet long.

Identifying your Linear model is straightforward if the original label is still intact. Look at the body of the operator, usually on the side or bottom of the control box, for a metal or vinyl tag that names the model and serial number. If the label is sun-bleached or gone, which happens to plenty of Texas gates after a decade of summer heat, we identify the operator by the arm style and the gate’s weight and length. One compatibility gotcha with Linear is that older ACT series operators used a different control board connector than newer production runs. So a motor swap isn’t always plug-and-play if the board is the original; sometimes the board and motor should be replaced together so they communicate correctly. We keep both OEM Linear parts and quality aftermarket equivalents on hand, and we’ll tell you upfront which makes sense for your gate rather than defaulting to whatever costs more.

We’re an independent San Antonio gate company, not a Linear dealer, so our recommendation on parts is based on which one will last longest on your particular gate, not on a brand agreement.

Signs Your Linear Gate Motor Replacement Is Failing

• The gate hums but doesn’t move. The motor is getting power and trying to run, but the start capacitor or drive gear has failed. On Linear ACT operators, the most common first failure is the drive gear stripping where the arm meets the motor shaft.
• The gate opens a few feet and stops, or reverses on its own. The motor’s stall current sensor is triggering because the gate is now harder to move than the operator expects. Hinge wear, a sagging gate, or a failing motor can all cause this, so we check all three before we condemn the motor.
• The breaker trips every time the gate runs. A motor that’s drawing high current, usually from windings starting to short or a seized gearbox, will pull more amperage than the circuit can supply. This is a fire risk if left alone, so it’s the symptom we treat most seriously.
• The gate moves noticeably slower than it used to. Motor torque drops off as windings age or capacitors weaken. What used to take 12 seconds might now take 20 or more. The motor is fading before it fails.
• You hear grinding or clicking from inside the operator housing. That’s usually the gear set, not a minor noise. Once gears start shedding metal, the motor has to work harder and the end feels worse than it sounds.

Replacement Cost & What’s Included

In San Antonio, expect a Linear swing-arm motor replacement to fall between $1,100 and $1,800 installed for a standard residential single gate. Slide-gate Linear motor replacements typically run $1,600 to $2,600 because the motors are heavier, the gates are longer, and the work involves more mechanical alignment. The range depends on whether you’re matching an existing arm, replacing the control board at the same time, and how much hinge or track correction the gate needs so the new motor isn’t pulling against a worn-out gate.

Here’s what a typical Linear swing motor replacement looks like on paper:

• Replacement Linear-compatible motor and gearbox: $600 to $950
• Control board (if the connector style requires it): $180 to $320
• Labor, including mounting, wiring, and travel-limit setup: $320 to $530
• Gate adjustment (hinge shims, post correction if needed): $0 to $250

DIY or Call Us?

The honest answer is that a Linear gate motor swap is not a safe DIY project for most homeowners. These operators run on 120V or 240V, and a swing gate under power can move with enough force to hurt a kid or a dog if the travel limits aren’t set correctly after the swap. What you can safely do is confirm the basics before you call: check that the breaker for the gate circuit is on, look for obvious arm damage, and note exactly what the motor does when you press the remote. That information helps us bring the right parts on the first visit.

What we don’t recommend you do is open the operator housing with the power live, or try to force a gear back into position. We’ve followed more than a few YouTube-guided repairs in San Antonio where someone replaced a capacitor but left the real problem untouched, and the gate failed again two weeks later. If you want this done once, call us at (325) 252-5195 and let us match the right Linear motor to your gate’s actual weight and usage.
