Linear Gate Motor Replacement: The Sherman Oaks Owner’s Guide
We stock Linear-compatible gate motors and replacement parts on the truck, and most Sherman Oaks driveway gate motor replacements run between $850 and $1,900 installed, depending on the model and whether the existing bracket and arm assembly can be reused. We can typically complete the swap the same day we diagnose it.

Most Sherman Oaks homeowners find out their Linear motor has failed the hard way: the gate stops mid-travel, hums without moving, or a neighbor calls to say the gate has been sitting open since morning. By the time you’re reading this, you’ve probably already noticed the control board clicking but the arm not moving, or the operator doing nothing at all while the keypad still lights up. That’s the profile of a Linear motor that’s done its time, not a wiring glitch.
Adrian Vance has been replacing these exact operators on Sherman Oaks properties since 2014. I’ll tell you what I found, what it costs to fix it, and what you’ll have when I leave. That starts with a written price before we touch a tool, and it ends with a photo log of every part we installed and every reading we set.
Key takeaways:
- Linear gate motor replacement in Sherman Oaks typically costs $850 to $1,900 installed, quoted in writing before work begins
- Most Linear failures trace to the motor itself or the capacitor, not the control board
- We stock Linear-compatible motors and OEM-equivalent parts for same-day swap in most cases
- We’re an independent service provider, not affiliated with Linear, and we repair or replace whatever brand is already on the property
- Every replacement includes a documented photo record and the 365-Day Done Right Promise
Which Linear Models This Applies To
Most of the Linear operators we swap in Sherman Oaks fall into three families: the LRA chain-drive and belt-drive swing operators, the APeX and AR series residential swing arms, and the VS series vertical-pivot operators you see on compound-style gates along Mulholland and up the canyon. The compatibility gotcha with Linear is the arm style. An LRA arm won’t mate to an APeX chassis, and a VS-series motor has different limit-switch geometry than either one, so matching the operator to the exact post-mount matters more than the horsepower number. The model label is on the underside of the metal cover, usually a white sticker with a two or three letter prefix followed by three digits. If the sticker is sun-baked to illegibility, we match by measuring the arm throw and the mounting bolt pattern.
On OEM versus aftermarket: Linear was sold to Nortek Control, then to Nice S.p.A., and the current brand has gone through enough ownership changes that some exact-match motor assemblies are no longer manufactured. When a direct Linear replacement motor isn’t available, we use quality aftermarket equivalents that match the existing arm ratio and limit-switch travel. For most Sherman Oaks installations, an aftermarket motor with matched specs is the better value, and we document the exact part number installed so nobody has to guess during the next service call.
Signs Your Linear Gate Motor Replacement Is Failing

- The gate hums but the arm doesn’t move. This usually means the start capacitor has failed, or the motor brushes are gone after years of cycling. A humming operator is a motor that wants to work and doesn’t have the kick left to do it.
- The gate stops under load, then reopens. Linear operators read resistance as an obstruction signal, and a weak motor registers its own strain as an obstacle. This is common on heavy iron gates where the motor has been undersized for the leaf weight.
- It works wet and fails dry, or vice versa. Moisture-driven intermittent failures around the motor windings or gearbox seals are common in Sherman Oaks, especially near the hillside sprinkler zones where micro-emitters soak the operator base every morning.
- The arm moves in jerks or creeps on start. Worn gear teeth or a slipping clutch show up as hesitation before the gate gets moving. If you hear a metallic rattle on startup, the gearbox is on its way out and dragging the motor with it.
- The operator trips its breaker or blows the low-voltage fuse. A motor drawing too many amps at stall is either binding or shorted. This tends to get worse over weeks, not days. We find a lot of these in Sherman Oaks where gate bearings have worn and the motor has been compensating until it couldn’t.

AfterReplacement Cost & What’s Included
In Sherman Oaks, most Linear gate motor replacements land between $850 and $1,900 installed. The spread comes from two things: whether the operator is a light residential swing arm or a heavier linear-ram unit, and whether the existing bracket, gate hinge hardware, and limit set can be reused. A straight motor swap on an intact LRA usually runs at the low end. A full operator replacement with a new arm, re-set limits, and a re-synced photo-eye lands at the top of the range.

What’s included: the motor or full operator, the swap labor, limit adjustment, force and obstruction calibration, and a written record with photos of what was installed and how it was set. The price is handed to you in writing before any work starts, under Haven Standard Clause 1. We don’t work on “estimates” that turn into a bigger number later. The number we write is the number you pay. Every replacement is covered by our 365-Day Done Right Promise: if it isn’t right, we make it right, no argument and no charge within that year.
DIY or Call Us?

There’s a voltage warning that belongs right here: Linear operators run on 120V or 240V line current, and the capacitor inside the motor housing stores enough charge to deliver a serious shock even with the power off. This is not a part to swap by feel. The forces involved, a moving gate leaf under a failing motor, are also not forgiving. A gate that drops because the limit was set wrong can hurt someone or crush a vehicle.
What you can check safely: whether the breaker and GFCI are tripped, whether the keypad and safety beam are getting power, and whether there’s visible damage to the arm or post bracket. That’s the diagnostic that costs nothing. What you shouldn’t do is open the operator cover and start swapping motor wiring, because the parts that fail inside a Linear are exactly the parts that bite. If you’ve already got the cover off and you’re not sure what you’re looking at, close it and call us at (213) 463-6296. We’ll give you a straight answer and a written price, either way.
FAQs
In Sherman Oaks, a Linear gate motor typically lasts 8 to 12 years, and the motor itself is rarely what dies first. The start capacitor and gearbox seals tend to go before the windings give out, and our sun here ages limit-switch housings faster than you’d see in a coastal climate. If the gate still moves but strains, the motor may have years left in it with the right sub-component replaced.
It depends on whether the failure is in the capacitor, gearbox, limit assembly, or motor windings. A failed capacitor or limit switch is a repair, and we do those all the time in Sherman Oaks for under $400. A shorted winding or seized gearbox is a replacement, because rebuilding a burnt motor costs more than a new matched unit. We’ll diagnose what actually failed, show you the failed part and the test result, and quote the repair or replacement accordingly. Call (213) 463-6296 if you want a straight answer to a specific gate.
Most Sherman Oaks Linear gate motor replacements take two to three hours from arrival to a fully re-set and tested operator. If the existing bracket and arm assembly are intact, we can usually finish faster. If the post bracket is cracked, the gate itself needs re-hanging or re-welding, or the power feed is compromised, the job runs longer and we’ll tell you exactly how much longer before we start.
We stock Linear-compatible replacement motors, capacitors, limit-switch kits, and arm assemblies on the truck for the most common residential Linear operators in Sherman Oaks. For less common models, like an older VS series vertical-pivot unit, we source next-day and bill the same written price. It’s rarely more than a day of waiting, and we’d rather wait for the right part than install something that sort of works. We also carry parts for LiftMaster, Mighty Mule, and Ghost Controls, so if the problem turns out to be a different brand on the property, we’re already prepared.
