Linear Gate Motor Replacement Nationwide | Gatewood Fence & Gate

Linear Gate Motor Replacement: The Prosper Owner’s Guide

We stock and install Linear-compatible gate motor replacements across Prosper, and most swaps run between $650 and $1,400 installed depending on the series and whether we’re replacing just the operator head or the full arm assembly too. If you call before noon, we can usually have the new motor in and your gate running the same day. The call usually starts the same way: “It was working fine yesterday, and today it just hums and won’t move” or “It opens halfway and gives up.” That’s the failing motor telling you it’s done.

Here’s what you need to know before you buy anything: Linear made several distinct motor lines over the years, and the part that fits an LDO50 swing arm won’t bolt onto an APeX or an old LRA residential slide unit. The model plate on the side of the operator tells you everything, but half the ones we see have been sun-bleached until the sticker’s unreadable. When that happens, we match by measuring the arm travel, the mounting bolt pattern, and the motor’s voltage and amp draw. Hal Gatewood has been matching Linear parts in driveways across Prosper since 2001, which means we’ve seen every sticker variation and every trick question this brand can throw at you.

One more thing before you start shopping: Gatewood Fence & Gate is an independent service provider. We’re not a Linear dealer, we don’t answer to Linear, and we’ll tell you honestly when a quality aftermarket motor does the same job for less than the OEM box. That matters when you’re pricing a repair on a gate that’s already ten years old.

Which Linear Models This Applies To

Linear has built gate operators under several series names, and the compatibility question trips up a lot of owners shopping online. The main lines we replace in this area are the LDO swing-arm series (LDO50, LDO33), the APeX series (APeX-5, APeX-3, APeX-1), and the older LRA and SLR slide-gate units still running on plenty of Prosper acreage. Each series uses its own motor type and gear reduction, and within the LDO line the LDO50 has a longer arm stroke and heavier-duty motor than the LDO33, so they are not interchangeable parts.

Here’s a compatibility gotcha worth knowing: an LDO50 arm will physically mount to some LDO33 brackets, but the travel limits and torque curve don’t match, and the motor burns out early fighting the geometry. We see that exact mismatch once or twice a month, usually installed by a handyman who “found a deal online.” The way to identify your part correctly is to read the model plate on the operator cover first. If that’s unreadable, we measure the arm stroke (the LDO50 travels a longer arc), check the capacitor rating (the 50 uses a higher microfarad start capacitor), and confirm the motor’s continuous-duty amp rating. That ten minutes of checking saves you from buying the wrong part twice.

On the OEM versus aftermarket question, our honest position after 29 years of doing this work is that it depends on the unit’s age. For a Linear unit under five years old, we usually recommend the OEM Linear motor replacement because the rest of the operator still has substantial life left and the factory part carries the full warranty conversation. For older units, especially LRA and SLR models that Linear discontinued years ago, a quality aftermarket motor with the same frame size, capacitor spec, and duty rating often makes more financial sense, and in some cases the aftermarket part is the only thing still manufactured for that model.

Signs Your Linear Gate Motor Replacement Is Failing

• The motor hums but the gate doesn’t move. That’s the start capacitor failing or the motor’s centrifugal switch sticking. In the Texas heat, capacitor failure on Linear units is the single most common reason the motor won’t kick over, and it sounds exactly like a refrigerator that can’t quite start.
• The gate starts, then stalls halfway and reverses. The motor’s thermal overload is tripping because the windings are overheating. This is usually the beginning of the end, not a sensitivity adjustment, and it gets worse in summer when the motor’s already hot from the sun beating on the steel cover.
• You smell that hot electrical smell after the gate cycles. That’s insulation breaking down inside the motor windings. Once you can smell it, the motor’s running on borrowed time. We’ve unwound more than a few Linear motors where the winding varnish had baked to the color of roofing tar.
• The gate moves slower than it used to, especially when it’s cold. Cold weather thickens the gear grease and a weak motor struggles harder. In North Texas we get those February mornings where a tired Linear motor just refuses to push a heavy gate through cold grease.
• You hear grinding or a rhythmic thump while the gate moves. That’s gear wear inside the operator, not the motor itself, but it means the motor’s been working against a failing gear train and likely has the heat damage to show for it. Replacing the motor without addressing the gear wear means you’ll be doing this again inside a year.

Replacement Cost & What’s Included

In Prosper, an installed Linear gate motor replacement runs from $650 on the low end to about $1,400 when you’re replacing a full LDO50 arm assembly including the motor, gearbox, and limit controls. A solo motor swap on an APeX unit with the existing arm in good shape typically lands between $725 and $950. The range depends on which Linear series you have, whether we’re replacing just the motor or the motor and gearbox together, and whether the gate needs balancing work first so the new motor isn’t fighting the same fight that killed the old one.

Every price we quote includes the part, labor, and the trip, and you’ll get that number in writing before any work starts. We don’t quote one thing on the phone and another at the driveway. The 90-Day Done Right Promise applies to every replacement we do, and if we install a motor and the gate needs adjustment inside that window, one call brings Hal back, no runaround. You also get $40 off any repair over $200 and no trip charge inside the county, so the number you hear is the number you pay.

DIY or Call Us?

Here’s the honest split. If your gate motor hums but won’t start, you can safely test a couple things yourself: check that the circuit breaker for the gate hasn’t tripped, and look for any obvious obstruction binding the gate. That’s the boundary of what I’d recommend. A Linear gate motor swap involves 120-volt or 240-volt wiring, capacitor discharge, and re-tuning the open and close limits so the gate doesn’t slam or stall. A capacitor holds a charge even with the breaker off, and the arm on an LDO50 is under spring tension, which makes this genuinely dangerous work for someone who hasn’t done it before.

We’ve been called out to clean up enough DIY attempts where the gate was wired with wire nuts left sitting in water and the limits set so the gate whips past the stops. Hal’s been at this since he trained at Collin College and started fixing gates around Prosper when half these neighborhoods were still pasture, and he’ll tell you straight: a botched motor swap costs more than a proper one. If you want to run your situation by us before you decide, call (979) 291-0947 and describe what the gate’s doing. We’ll tell you honestly if it’s something you can handle or if you need us out there.
