Linear Gate Motor Replacement Nationwide

Linear Gate Motor Replacement: The San Jose Owner’s Guide

We replace Linear gate motors throughout San Jose, and a typical motor swap runs between $750 and $1,250 installed, parts included. Most replacements are done the same day we arrive, because we stock the common Linear-compatible motors and control components on the truck. When a Linear motor goes down, you usually notice it as a gate that hums but won’t move, moves an inch then stops, or has gone completely silent. If you’re standing in your driveway off Meridian Avenue or up near Alum Rock watching your gate do nothing, that’s the call we answer.

One thing to know early: Calder Gate Repair is an independent service provider. We are not affiliated with Linear, but we work with their equipment constantly and we keep replacement motors, boards, and arms ready for the models we see most in this California climate. Nico Alvarez, our owner and lead technician, will tell you straight: if he can’t explain the repair in plain English, he hasn’t understood it well enough yet.

Which Linear Models This Applies To

Most Linear gate operators in San Jose fall into a few families: the LSO series swing openers, the LRA and APeX series for slide and swing gates, and the older linear arm operators you’ll find on plenty of driveways in neighborhoods like Willow Glen and Berryessa. The compatibility gotcha to know is that Linear LSO and APeX models don’t share the same motor carriage or RPM rating, and the actuator stroke length has to match the swing distance of your gate exactly. A motor with the wrong stroke length will either throw the gate too fast or stall it mid-travel, and both failures eat limit switches and clutch gears fast.

If you’re trying to identify the right replacement, open the operator cover and find the silver or white data plate. You’ll see a model prefix and a production date. If the plate is sun-faded beyond reading, measure the actuator arm from mount point to mount point while the gate is closed and we’ll cross-reference it against the Linear spec sheet. We also carry quality aftermarket equals and Linear OEM parts, and we’ll show you the price difference before we order anything. For older units installed before Linear moved to the newer APeX and LSO boards, the wise spend is often a motor-and-board pair, not just a motor, because the old control logic is what killed the motor in the first place.

Signs Your Linear Gate Motor Replacement Is Failing

• Gate hums for a second, then nothing. The motor’s starter capacitor is dying or the arm is bound, and the motor is pulling more amps than it’s built to handle. That hum is the motor trying to start and failing.
• Gate travels a few inches and reverses. This is usually a worn limit cam or a failed internal gear. In Linear units you’ll also see this when the RPM sensor is dirty, so the board thinks the gate is binding and reverses it on purpose.
• Gate moves slower every month. Motor windings degrade over time, and in California heat that process runs faster than the manufacturer’s lifespan numbers suggest. If your Linear opener is 8 to 12 years old and sluggish, the motor isn’t healing itself.
• You hear grinding or a metal-on-metal scrape. The gear head inside the motor housing is stripping. Once the gear teeth start shedding metal, the motor works harder, runs hotter, and fails sooner.
• Gate won’t move at all and there’s no noise. Either the motor’s internal thermal overload has tripped, the capacitor failed completely, or the board stopped sending voltage. We test for all three before recommending a motor.

Replacement Cost & What’s Included

In San Jose, a Linear gate motor replacement installed by Calder Gate Repair runs about $750 to $1,250 for most swing gate setups, and $900 to $1,400 for slide gate motors because the rack and chain alignment adds labor. The spread comes down to which Linear model you have, whether the arm stroke and mounting bracket exact match or need modification, and whether the old board gets reused or needs replacing at the same time. California sun exposure shortens capacitor and winding life, so we often recommend doing the motor and the control board in one visit rather than paying for a second service call in a year. You’ll get a written price before any work starts, and that number is the number you pay.

Every replacement includes the motor, rewiring where the old connectors are brittle, a full limit switch adjustment, and torque setting. It also carries the 365-Day Done Right Promise: if the repair fails within a year, Calder returns at no charge, and that’s stated in writing on every job.

DIY or Call Us?

You can safely check a few things before calling: confirm the breaker hasn’t tripped, clear debris from the gate track, and check for obvious physical damage to the arm. What you shouldn’t do is open the motor housing and start pulling wires or swapping parts. Gate operators run on 120V or 240V with a motor capacitor that can hold a charge after power is cut, and a short from a miswired capacitor will fry the new board you just installed. We see it a few times a year, and the repair costs more than the motor swap would have the first time.

If the gate is off its travel path, jamming, or you smell burnt electrical when you stand near the operator, that’s the point to stop and call us at (669) 666-6859. A trained technician gets it sorted without turning a $900 job into a $2,100 board, motor, and wiring job.
