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 between $850 and $1,450 installed, depending on the model series and whether the arm bracket, limit switches, and wiring are still sound. We stock Linear-compatible motors and Linear OEM parts on our trucks, and in most cases we complete the swap the same day we diagnose the failure.

Most homeowners discover the problem the same way: the gate worked fine for years, then one morning it hums, clicks, or does nothing at all. Sometimes the arm moves a few inches and stops. Sometimes the remote does its job but the motor sits silent. That’s the point where knowing the exact Linear model saves time and money, because not every Linear motor fits every Linear gate.

Which Linear Models This Applies To

The Linear brand covers a wide spread of residential swing and slide gate operators. The most common models we replace in West Palm Beach are from the Linear Pro Access line, primarily the APeX series, the older LS series for slide gates, and the ubiquitous LDO50 and LDO33 single and dual swing arm operators. Each series has different mounting geometry, different arm travel, and different control board logic, so matching the motor to the original plate matters.

The surest way to identify what you have: open the control box cover and read the model plate. It’s printed on a white or silver sticker, usually near the terminal strip. If the sticker is sun-bleached or missing (common after a decade of Florida sun), take a photo of the arm, the control board, and the overall gate width. A Linear APeX arm brackets differently than a Linear LDO50, and mounting the wrong arm onto the wrong post means the gate either binds or fails at the gearbox within months.

One compatibility gotcha that catches owners off guard: Linear changed the control board pinout between older and newer APeX revisions. A motor swapped without matching board firmware can run but refuse to respond to limit inputs. We check board revision before we order or install anything.

For OEM versus aftermarket: we install genuine Linear parts when the operator is newer and the board is factory-fresh, because the warranty holds and the limit logic stays consistent. For older units where Linear parts are backordered or the board is already on borrowed time, quality aftermarket equivalents from brands like US Automatic and Aleko work well when paired with the correct transformer rating and arm length. We won’t put an undersized aftermarket capacitor into a Linear swing arm and call it done. It’s a false economy in the Florida heat.

We’re an independent service provider, not affiliated with Linear or Nortek, but we service the full Linear residential line and keep the common failure parts on hand: capacitors, limit switch sets, control boards, and complete actuator arms.

Signs Your Linear Gate Motor Replacement Is Failing

• Hum or buzz with no movement. The capacitor is failing or the start winding is gone. In a Linear swing arm, this usually means the motor is working electrically but can’t generate enough torque to move the gate leaf. The capacitor is a $30 part; a seized gearbox is not.
• Gate stops mid-travel and reverses. This is almost always a limit switch issue or an obstruction sensor picking up a false reading. On Linear units, the internal limit cams can slip after years of heat cycling, so the board thinks the gate has hit the close limit when it’s only halfway home.
• Slow, labored movement. The gearbox grease has broken down or the arm hinge pins are corroded. West Palm Beach’s salt air and wet summers accelerate this more than most people expect. A motor working against a binding hinge draws higher current and burns out faster.
• Gate drifts or won’t hold position. The motor’s internal brake, or in some Linear swing arms the ACME screw, is worn. The gate should not move when closed unless someone pushes it. If it drifts, the mechanical retention has failed, and no amount of limit switch adjustment fixes that.
• No response at all, but the board shows power. The motor windings are open, or the run relay on the control board has failed. A technician with a multimeter can distinguish these in five minutes. This is the failure where replacing the motor alone without checking the board means paying twice.

Replacement Cost & What’s Included

In West Palm Beach, an installed Linear gate motor replacement lands between $850 and $1,450. The spread depends on whether you need a swing arm actuator or a slide gate motor and chain, whether the existing mounting brackets are reusable, and whether the control board needs replacement alongside the motor.

Every quote is written before any work starts, under Haven Standard Clause 1. That written price includes the motor or actuator, the bracket hardware, limit setup, force settings, and a full travel test in both directions. You will not see an invoice larger than the quote, ever.

The part and the labor are covered by the 365-Day Done Right Promise. If the motor fails or the gate runs out of adjustment within a year, we fix it at no additional charge.

DIY or Call Us?

This is not a part to replace yourself. A Linear swing arm actuator contains a high-torque motor driving a screw mechanism under load, and a slide gate motor moves hundreds of pounds of steel. Both operate on 120V or 240V, and both have pinch points that can crush fingers or break a hand if the arm activates during installation. The control board terminals carry live voltage even with the gate motion disabled. If you’re not comfortable working inside a live electrical panel, this is a job for a trained technician with the right tools and insulated test leads.

What you can safely check: whether the breaker is on, whether the remote battery is dead, and whether debris is blocking the track or hinge path. If those are clear and the motor still won’t run, call us at (561) 725-8048. We’ll send a technician who will tell you what was found, what it takes to fix it, and what you’ll have when we leave.
