Linear Gate Motor Replacement Nationwide

Linear Gate Motor Replacement: The West Palm Beach Owner’s Guide

A Linear gate motor replacement in West Palm Beach typically runs $650 to $1,400 installed, depending on the model, swing versus slide configuration, and whether the arm or receiver board needs replacing alongside the motor. We stock Linear-compatible motors and parts on the truck, and most single-gate swaps are completed the same day. The usual way owners discover the motor has failed is simple: the gate stops opening, or it opens halfway and reverses, or the keypad works but the arm just hums and doesn’t move.

If you’re reading this, you already know which brand is on the gate. That saves time. Linear has been on Florida gates for decades, and the failure patterns in this climate are consistent: corrosion in the limit switch terminals, a receiver board that stops recognizing remotes after a season of humidity, or a drive gear that strips after years of salt-air exposure. As Lonnie Burke puts it, “Figure out what broke first. Everything else follows from that.” That’s how we price the job, and it’s why we don’t quote a full motor swap until we’ve confirmed the motor is actually dead.

Which Linear Models This Applies To

Linear has produced several operator lines over the years, and the compatibility specifics matter. The most common we see in West Palm Beach driveways are the LDO and LDCO series swing operators, the AL/LA slide gate operators, and older SL and S line units that homeowners have kept running well past their motor’s designed lifespan. The motors on these units aren’t all interchangeable, even within the same series. A Linear LDO50 and an LDO75 look similar from a distance, but the motor windings and starting capacitor ratings differ enough that dropping the wrong one in will burn out the board within weeks.

The reliable way to identify your model is the data plate on the operator chassis, usually on the inside of the cover or on the mounting plate. It lists the model number and voltage. If the plate is faded or paint-covered, take a clear photo of the operator body and the gear housing and we’ll match it from that. For OEM versus aftermarket on Linear specifically, our honest position is this: Linear OEM motors are good, but some of the aftermarket replacements built to the original spec, like the newer sealed-bearing units sold through the trade supply houses, actually hold up better in coastal Florida. The failure point is rarely the armature itself. It’s the exposed terminals and the capacitor, and the quality of those components is what separates a motor that lasts six years from one that lasts two.

One compatibility gotcha that catches people: a Linear swing operator motor that works fine on a 110-volt circuit will not work on a solar installation running through an inverter with unstable output. The inverter voltage sag under load is the fastest way to kill a new motor. If your gate runs on solar, say so when you call. We spec the motor differently.

Signs Your Linear Gate Motor Replacement Is Failing

• Gate reverses after opening a few feet. The motor is pulling higher amps than the board allows, which usually means a failing capacitor or the armature windings starting to short. The board trips the reversal circuit to protect the motor, but the underlying cause is the motor itself getting weak.
• Keypad and remotes work, but the arm only hums. This points to either a dead start capacitor or the gear train jamming against a stripped motor gear. A new capacitor is cheap. A stripped gear means the motor’s output shaft and pinion need replacement. We test for both before recommending anything.
• The gate moves at half speed, especially in the morning. Humidity overnight gets into the motor housing and creates a small current leak across the commutator. Once the day heats up, it runs closer to normal. This is the early warning sign in West Palm Beach, and it goes away only with a motor swap.
• Blown fuse or tripped breaker on the operator. The motor is drawing current even when the gate is idle, which is typical of a winding insulation breakdown. Florida heat accelerates that breakdown. If the fuse blows twice, the motor is done.
• Manual operation feels free, but the motor stalls under load. A gate that rolls or swings easily by hand but stalls when the motor runs means the motor has lost torque. That’s nearly always the gear reduction assembly or the motor’s internal magnets losing strength. Lubricating the hinges won’t fix this one.

Replacement Cost & What’s Included

For West Palm Beach, the installed price for a Linear gate motor replacement breaks down like this:

• Swing gate motor, single operator (LDO/LDCO class): $650 – $950 installed
• Slide gate motor with new chain and idler (AL/LA class): $850 – $1,200 installed
• Motor plus receiver board replacement: add $180 – $340 depending on the board revision
• Capacitor-only repair when the motor is still healthy: $95 – $160

The price includes the motor, installation, wiring terminations, travel limit reset, and a full system test under load. We write the exact number down before any work starts, and that number doesn’t change at the door. Everything is covered by our written guarantee for a full year. If it fails within that window, we come back and fix it free. No charge, no argument. That’s The Garrison Standard, and it’s been the same since 2008.

One note on price honesty: if a motor is healthy and the real problem is a $20 limit switch or a $40 capacitor, we’ll tell you that and replace the small part. We don’t sell motors that aren’t needed.

DIY or Call Us?

There are two safe checks you can do before calling. First, confirm the operator is getting power: test the outlet or the dedicated circuit breaker. Second, look at the wiring connections inside the operator housing. If you see green corrosion on the motor terminals or a burnt smell, that’s the smoking gun. There is nothing safe to attempt beyond that. Gate motors run on 110 or 220 volt input, and the capacitor inside holds a charge even after the power is disconnected. A charged capacitor across your hand is a genuinely painful and dangerous injury. We wear insulated gloves and discharge capacitors properly on every motor job. We recommend you don’t open the motor housing yourself.

If the motor is confirmed failing, the swap itself takes a trained technician about two hours for a swing gate or three for a slide gate, and we carry the motors, capacitors, and boards on the truck so there’s no second trip. Call (728) 203-2413 and a real person answers, day or night. We’ll schedule the visit, dispatch a background-checked and uniformed technician, and hand you a written price before a single tool comes out.
