Linear Gate Motor Replacement Nationwide

Linear Gate Motor Replacement: The West Hollywood Owner’s Guide

A Linear gate motor replacement in West Hollywood typically runs between $1,100 and $2,400 installed, depending on the model series and whether the swing-arm brackets and control board are still in good shape. We stock Linear-compatible swing and slide gate motors on our trucks and can usually complete the swap the same day we arrive, assuming no structural damage to the gate itself. Most homeowners discover the problem the hard way: the gate stops mid-arc, hums without moving, or refuses to respond to the remote after a rainstorm, and the limit switch reset that used to work no longer does.

The thing about Linear motors is they’re workhorses until they aren’t. When they go, they tend to go suddenly, leaving a 400-pound gate stuck exactly where it was when the internal capacitor finally gave out. Adrian Vance has been replacing these units since his commercial access-control days, and the pattern is consistent: the motor housing is usually fine, the internals are not.

Which Linear Models This Applies To

We replace motors across the Linear actuator and slide-gate operator lines: the LDCO series (LDCO 800, LDCO 841, LDCO 861), the LDO 250 and LDO 350 swing actuators, the SL and SLD slide operators, and the older ProLift and Megacode-era units still running on plenty of West Hollywood properties. The fastest way to identify what you have is to remove the cover and look for the silver data label on the motor housing itself, not the control board. That label gives you the model number, voltage (most residential Linear units in West Hollywood run 110V AC), and the serial number prefix that tells us which generation of internals we’re dealing with.

Here’s the compatibility gotcha most homeowners don’t know: Linear changed the internal gear-and-capacitor assembly on the LDCO series in 2019, and the newer control board will not communicate with the older actuator arm without a firmware-compatible daughter board. If someone tells you “any Linear motor will work,” walk away from that estimate. We match the replacement motor to the exact generation of your existing system, and we photograph the label before we order anything so there’s zero guesswork.

On the OEM versus aftermarket question for Linear specifically: we install both, and we’re honest about the tradeoff. OEM Linear motors carry a two-year factory warranty and match your existing wiring harness without modification. Quality aftermarket equivalents, usually from ALEKO or Topens, run $200 to $400 less and work fine, but the harness often needs a re-pinned connector. We’ll show you the price difference in writing and let you decide. Most West Hollywood customers with LDCO units end up on OEM, because the labor savings from a direct plug-in swap offsets the part markup.

Signs Your Linear Gate Motor Replacement Is Failing

• The gate starts, then reverses before reaching full travel. This is usually the internal current-sensing circuit misreading resistance from a worn gear train. The motor thinks something is blocking the gate and backs off. We see this most often on Linear units 6 years or older.
• The motor hums but the gate doesn’t move. That’s the start capacitor failing, which is the most common death of Linear motors in the West Hollywood heat. The capacitor sits inside the housing and bakes in direct sun for years; when it fails, the motor can’t build the torque to start the gate moving.
• The gate moves at half speed or staggers mid-travel. Worn internal nylon gears, common on the LDO 250 series. The gears are $60 to $90 in parts, but the labor to split the housing and re-align the limit cams often pushes people toward full motor replacement instead. We’ll price both.
• The remote only works from 10 feet away, then stops working altogether. This usually isn’t the remote at all. It’s the receiver board inside the motor drawing too much current as it fails, which drags down range gradually. If you’ve already replaced batteries in two different remotes, the motor is talking to you.
• You hear a clicking noise from inside the housing, and the gate doesn’t move at all. That’s the internal relay or limit switch assembly, and on sealed Linear units it’s not field-serviceable. The motor needs to come out.

Replacement Cost & What’s Included

Installed Linear gate motor replacement in West Hollywood runs between $1,100 and $2,400. Here’s what drives the spread:

• Linear swing actuator motors (LDO 250, LDO 350): $1,100 to $1,600 installed. Smaller part, less labor, usually one technician.
• Linear LDCO series (LDCO 800, LDCO 841, LDCO 861): $1,400 to $2,000 installed. These are the most common residential Linear units in West Hollywood.
• Linear slide operators (SLD series): $1,800 to $2,400 installed. Heavier unit, longer install, sometimes requires chain or rack adjustment on top of the motor swap.

The price includes the motor, removal and disposal of the old unit, mounting hardware, wiring reconnection, limit-switch calibration, and a documented photo record of every step: what we found, what we set, what we installed. If your existing arm bracket or gate mount is cracked or rusted through, that’s added to the quote as a line item before we touch it, never after. A written price goes in your hand before any work starts, under Haven Standard Clause 1. If the motor we install fails within a year, we replace it at no charge, parts and labor, no expiration-date games.

Key Takeaways:

• Linear motor replacement in West Hollywood: $1,100 to $2,400 installed, depending on series.
• We stock Linear-compatible motors on the truck; most swaps are same-day.
• 2019 is the compatibility cutoff on the LDCO line. Match the generation, not just the brand.
• You get a written price before we start and a photo log before we leave.

DIY or Call Us?

A Linear gate motor involves 110V AC wiring, a capacitor that holds a charge even with the power off, and a gate that weighs more than your car door. This is not a weekend project. We’ll say it plainly: if you open the housing and touch the capacitor terminals without discharging them correctly, you will get hurt. The capacitor inside a Linear LDCO unit holds enough charge to knock you off a ladder. If you want to save money, here’s what you can safely do yourself: check the breakers, verify the manual release works, note the exact model on the data label, and leave the rest alone. We’ll handle the electrical, the gear alignment, and the limit switches, and you’ll get a photo log showing exactly what we did. Call (424) 321-7416 and we’ll get a technician out with the right replacement on the truck.
