Linear Gate Motor Replacement Nationwide

Linear Gate Motor Replacement: The Los Angeles Owner’s Guide

We replace and install Linear-compatible gate motors across Los Angeles, with most complete motor swaps running $490 to $1,150 installed depending on your gate’s weight, swing arc, and whether we’re matching an existing Linear arm or reusing your brackets. The failure usually announces itself the same way: the gate moves slower than it did a year ago, the motor runs but the gate barely swings, or the opener hums and trips its breaker while the gate sits dead on its hinges. Most Los Angeles owners we hear from have been nursing a tired Linear motor for months – resetting the breaker, shoving the gate by hand, telling themselves it’ll hold “one more week.”

Call (903) 417-0793

Nico Alvarez has opened hundreds of Linear units over the years and will tell you the same thing: Linear built these motors to run for roughly 8 to 12 years in Los Angeles conditions. After that, the capacitor bank, the internal gear train, and the limit switch assembly all start competing to see which one quits first. We stock Linear-compatible replacement motors and gear assemblies on our trucks, which means we’re typically able to complete the swap the same day a technician is on site. If you’re watching a dead arm motor with a gate half-open and a car trapped in the driveway, call us at (903) 417-0793 – a live person answers and we’ll tell you straight what the repair will cost before anything gets unbolted.

Key Takeaways

• Linear arm motors are serviceable and replaceable – you rarely need a whole new gate operator
• Installed replacement in Los Angeles typically falls between $490 and $1,150 depending on gate weight and bracket compatibility
• We stock Linear-compatible motors on the truck, so most swaps happen same-visit
• Every job gets a written price before work starts, and the 365-Day Done Right Promise in writing
• Calder Gate Repair is an independent service provider – we’re not affiliated with Linear, but we’re factory-familiar with their entire swing-arm lineup

Which Linear Models This Applies To

The Linear swing-arm gate operator family covers a lot of Los Angeles driveways. If your unit says LRA, LS, or SwingArm anywhere on the cover sticker, the motor internals we’re describing here are almost certainly your failure point. Specific models we see week in and week out include the Linear LRA-S, LS-A, LRA-XL, SW Series, and the older APeX and MegaCode swing operators that predate them. The common thread across the family is a 24V DC or low-voltage AC motor that bolts to a reduction gearbox inside the arm housing.

Here’s the compatibility gotcha that saves Los Angeles homeowners from buying the wrong part: Linear changed their internal motor mounting pattern in the mid-2010s transition from the APeX series to the LRA series. A motor sold for an APeX-era arm will not bolt directly into an LRA housing without an adapter plate, even though the arm length looks identical from the outside. Before any replacement, we check the model sticker, measure the motor face plate, and confirm the gear pitch so the new motor seats correctly the first time. When it comes to OEM versus aftermarket, we’re honest about the tradeoff: genuine Linear replacement motors carry top dollar but match perfectly. Quality aftermarket equivalents – the ones we stock – use the same gear pitch and voltage spec at roughly 60% of the OEM price, and we’ve been installing them in Los Angeles for years with the same 365-day warranty behind them.

Signs Your Linear Gate Motor Replacement Is Failing

A Linear gate motor gives you plenty of warning before it stops completely. If you catch it early, the fix is cheaper and your gate never leaves you stranded. Here’s what Los Angeles owners call us about, in order of how often we see it:

• Motor hums but gate doesn’t move. The run capacitor has lost its charge – a known weak point on Linear swing arms older than 8 years. The motor is getting power but can’t build the starting torque to push a 300-pound gate. This is almost always the capacitor bank or a seized gear train.
• Gate swings slower every week. As the internal plastic worm gear wears, the reduction ratio effectively changes. The motor is working harder to achieve the same swing, and it’s the clearest early sign that the motor and gear set need attention before the motor windings cook themselves.
• Gate stops mid-swing and reverses for no reason. On Linear units, the internal limit switch – the small sensor that tells the gate when it’s reached the open or closed position – sits inside the motor housing, not on the gate post. When it drifts, the control board gets confused about where the gate actually is, and the gate gives up mid-arc.
• Breaker trips when the gate opens. The motor is drawing more current than the circuit will allow. In Los Angeles heat especially, a motor with aging windings will overheat and trip the breaker, then work again once it cools – right up until it doesn’t come back at all.
• The manual release won’t disengage the motor. If pulling the manual release lever feels like it’s fighting you, the reduction gear inside the arm housing has likely seized. The motor still runs free, but the gear is locked. We see this most often on gates that sit unopened for months at a time.

Replacement Cost & What’s Included

For most Los Angeles homes, a Linear gate motor replacement runs $490 to $1,150 installed. The range breaks down like this: the motor and gear assembly itself is typically $220 to $440 depending on whether we use an OEM Linear replacement or a quality aftermarket equivalent. Labor is usually $180 to $320, covering the pull-apart, motor swap, gear alignment, and limit switch recalibration. The rest of the variance comes from what else is wrong once we’re inside – a cracked arm housing, a corroded wiring harness, or a bracket that needs re-welding after years of pushing against a sagging gate.

Every quote we give in Los Angeles is a written price before any work starts. The number on the invoice is the number Nico agreed to when he gave the estimate. That’s not optional and it’s not negotiable – it’s how we’ve run this shop from day one. The replacement motor carries our 365-Day Done Right Promise: if the repair fails within a year, Calder Gate Repair comes back and makes it right at no charge. That’s in writing on every job. You also get a free second visit if something isn’t right, for any reason.

DIY or Call Us?

The honest split is this: there are two things a Los Angeles homeowner can safely check before calling us, and there’s one place you should stop.

The safe checks: reset the breaker and test whether the gate’s manual release lever moves the gate freely by hand. If the gate swings smoothly and the motor still won’t turn it, the motor is confirmed dead and the smart money stops there. The stop point is opening the arm housing yourself. Linear arm motors run on 24V to 120V internally, and the capacitor bank holds a stored charge even with the breaker off. Mis-handle a charged capacitor and you’ll get more than a surprise. Beyond the electrical risk, gear alignment is not a bolt-off-bolt-on job – a motor installed a few degrees out of alignment will destroy the new gear set within a month, turning an $800 replacement into an $800 repeat. Tell me what it’s doing, and I’ll tell you what it’ll cost – before I touch anything. Call (903) 417-0793 and we’ll walk through the symptoms and get you a written number the same day.
