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 $850 and $1,900 installed, depending on the model and whether we’re swapping the motor head only or the full operator assembly. We stock Linear-compatible motors on our trucks and complete most replacements in a single visit, usually within two to three hours of arriving. You’ll know it’s time when the gate starts moving slower than it did last year, makes a grinding sound on startup, or trips its breaker in the middle of a cycle. Most West Hollywood homeowners call us after the gate has quit entirely, often on a Friday when the driveway becomes a parking lot for a dinner party.

Which Linear Models This Applies To

This replacement guide covers the Linear slide and swing gate operators still in service across West Hollywood’s hillside properties and flatland estates: the LDO series (LDO50, LDO33), the SL series swing operators (SL2000), and the older APeX and MegaCode lines that Linear built their reputation on. If you open your control box and the nameplate says Linear with a model number starting in LDO, SL, or APeX, this is your page.

The compatibility gotcha worth knowing: Linear changed their motor coupling design between the APeX-era units and the current LDO generation, so a motor from a 2008 APeX will not bolt into a 2019 LDO housing without an adapter plate and shaft spacer. Field-measure the motor shaft diameter before ordering anything online. It’s either 5/8 inch or 3/4 inch, and guessing wrong means a return trip. We match the motor to the exact armature winding spec Linear used in your series, rather than dropping in a universal motor and hoping the torque curve behaves. For most West Hollywood homeowners, we recommend OEM Linear motors when the operator is under ten years old and still has life in the control board. On older systems where the board is next to fail, a quality aftermarket equivalent with a two-year warranty often makes better financial sense. We carry both, and we’ll tell you honestly which one fits your gate and your budget.

Signs Your Linear Gate Motor Replacement Is Failing

• The gate hesitates or stalls mid-cycle. The motor’s start capacitor is losing its ability to kick the armature into motion under load. West Hollywood’s summer heat accelerates capacitor aging, and a gate that stalls on a 95-degree afternoon but works at 8 a.m. is telling you the capacitor is done.
• A grinding or squealing sound on startup. The motor shaft bearing or the drive gear has worn past tolerance. Linear units run a hardened steel worm gear against a bronze gear, and once that bronze gear loses its tooth profile, the motor has to work harder every cycle until it overheats.
• The overload breaker trips more than once a week. The motor is pulling too many amps, usually because a failing bearing or a gate that’s fallen out of adjustment has increased the mechanical load. Replacing the motor without checking the gate hinge alignment means you’ll replace it again in two years.
• The gate moves noticeably slower than it did six months ago. Brush wear inside the DC motors on LDO units is the usual cause. Linear DC motors have replaceable brushes, but once the commutator is scored, the whole motor assembly needs replacement.
• Burning smell from the control box. Shut the system off at the breaker and call us. This is thermal damage to the motor windings, and continuing to run it will take out the control board next. We see this most on West Hollywood gates that cycle more than 40 times a day, which is common on duplex and small apartment driveways off Santa Monica Boulevard.

Replacement Cost & What’s Included

Here’s what a Linear gate motor replacement costs in West Hollywood, installed, with no surprises on the bill:

• OEM Linear motor head replacement: $850 to $1,300 depending on series and model
• Motor plus gear train (recommended on units over 12 years old): $1,100 to $1,600
• Full operator replacement when the control board is also failing: $1,500 to $1,900
• Gate alignment or hinge correction, when needed: $150 to $400, quoted separately before any work begins

The range comes down to model series, what’s reusable, and whether the gate itself needs mechanical correction. We always quote the price upfront and get your agreement before we turn a single bolt. Every Linear replacement we install carries the 90-Day Done Right Promise in writing: if it is not right, we come back and make it right, no paperwork, no arguing. That’s the Keystone Standard on every job, whether you’re two blocks off Melrose or up in the hills above Sunset.

DIY or Call Us?

Replacing a Linear gate motor involves 120-volt line wiring, capacitor discharge, and mechanical load adjustment. If you have a multimeter, insulated tools, and you understand how to safely discharge a capacitor, you can perform the removal and bench-test the motor yourself. What you should not do is wire a new motor into a live control board or attempt to set the limit switches and torque adjustments without a service manual for your specific Linear series. Getting the torque limit wrong on a gate motor turns the gate into a pinch hazard, and a control board short from an incorrect wire pairing will cost more than the labor would have. We’re happy to handle the whole job, or if you’ve already sourced your own motor, we’ll install it and set the limits correctly. Call (442) 255-3886 and we’ll give you a straight answer on what you’re looking at.
