Linear Gate Motor Replacement: The Simi Valley Owner’s Guide
A Linear gate motor replacement in Simi Valley typically runs between $850 and $1,650 installed, depending on the model and whether the arm, bracket, and control board can be reused. We stock Linear-compatible motors on our trucks and can usually complete the swap the same day we diagnose the failure. Most homeowners in Simi Valley discover the motor has died the hard way: the gate was working fine last week, and this morning it just sits there, humming faintly or not making a sound at all.
What you’re looking at is usually one of two failures: the motor’s internal capacitor gave out after years of Southern California heat cycles, or the gear assembly stripped a tooth and the arm can’t translate power anymore. Either way, the fix is the same general shape: match the motor, swap it, set the limits, verify the safety edges, and document everything. Adrian Vance has handled enough of these to know the difference between a motor that’s truly dead and one that just needs a limit switch reset – and you’ll know which one you have before anyone picks up a tool.
Key takeaways:
- Linear gate motor replacement in Simi Valley: $850-$1,650 installed, written price before work starts
- We carry Linear-compatible motors and aftermarket equivalents on the truck
- Same-day completion on most replacements once the failure is confirmed
- 365-Day Done Right Promise covers every motor we install
Which Linear Models This Applies To
Linear built two main swing-gate motor platforms that dominate driveways across Simi Valley: the older LRA and L-Series operators (LRA10, LRA18, LRA22), and the newer APeX and TiltMaster lines. Slide gates run on the SL series, most commonly the SL4 and SL10, and those have their own replacement logic. If your motor housing says LINEAR on the side but the label is sun-baked and unreadable – common after a Simi Valley summer – we can identify it by measuring the arm stroke and checking the transformer output in about ten minutes.
The compatibility gotcha with Linear is the arm bracket. On the LRA series, the motor ships with a cast-aluminum articulated arm bracket that many owners never replace. When the new motor goes in, we check that bracket for hairline cracks and wallowed-out pivot holes. If it’s worn, you want it replaced at the same time, because a new motor pushing through a worn bracket will eat its own gear set within a year. That’s the kind of thing that doesn’t show up in a parts catalog diagram but makes the difference between a repair that lasts and one that doesn’t.
On the OEM versus aftermarket question: Linear’s OEM motors are solid, and for most LRA and APeX operators we install them when the homeowner wants an exact match. But there are quality aftermarket equivalents for the LRA series that we’ve installed without issue, and they typically save $150 to $250 on the part. We’ll show you both prices on the written estimate and let you decide. We’re an independent service provider – not affiliated with Linear – which is exactly why you get an honest comparison instead of a brand loyalty lecture.
Signs Your Linear Gate Motor Replacement Is Failing

- The motor hums but the gate doesn’t move. The capacitor that gives the motor its starting torque has failed, or a stripped gear is letting the motor spin without engaging the drive train. Both are replaceable, and both generate the same sound.
- The gate moves halfway and stops, then reverses. This is usually a limit switch drifting out of calibration, but on older Linear LRA units, it can also mean the motor is overheating and tripping the thermal overload. We check the current draw at the transformer to tell the difference.
- The gate opens fine but struggles to close – or vice versa. Uneven strain like this points to a motor with a failing capacitor or worn internal bearings, not a hinge problem. If the hinges were the issue, the struggle would show up in both directions.
- The motor housing is hot to the touch after a cycle. Linear motors run warm in Simi Valley heat, but a housing that’s uncomfortable to hold means internal resistance – bad bearings, degraded windings, or a failing capacitor. That’s the motor telling you it’s running hard just to perform normally.
- The gate was fine until a power outage, and now the motor runs in reverse or not at all. Power spikes and brownouts are rough on Linear control boards. If the board survived but the motor got spiked, you’ll see erratic behavior that looks like a programming issue but is actually the motor’s internal electronics scrambling.

AfterReplacement Cost & What’s Included
Here’s the pricing picture for Linear gate motor replacement in Simi Valley. All prices include the motor, labor, limit calibration, and full safety verification before we leave.
- LRA10 / LRA18 swing-gate motor replacement: $850-$1,150 installed
- LRA22 or APeX swing-gate motor replacement: $1,100-$1,450 installed
- SL series slide-gate motor replacement: $1,200-$1,650 installed
- Arm bracket replacement (if needed): $95-$180 depending on condition
- Control board replacement (if failed alongside motor): $300-$525
What drives the range: whether the arm bracket is reusable, whether the motor mounts directly to the existing bolt pattern or needs a new mounting plate, and whether the control board survived whatever killed the motor. We’ll know all of that before we give you the number. Under Haven Standard Clause 1, you get a written price before any work starts – not after. Every motor we replace carries the 365-Day Done Right Promise: if it’s not right within a year, we make it right at no charge.
DIY or Call Us?

Let’s be honest about the electrical risk first. A Linear gate motor is a 120V or 240V device wired directly into your panel or a nearby junction box, and the start capacitor can hold a charge even with power disconnected. If you’re not comfortable working around live electrical connections and you don’t own a multimeter, this is not a weekend project. The danger is real, and we’d rather see you call us than end up in an urgent care with a capacitor burn.
What you can safely check before you call: confirm the breaker is on, check that the power switch on the motor housing hasn’t been bumped off, and look at the arm pivot points for obvious binding or debris. Those three checks solve a surprising number of “dead motor” calls and save you the trip charge. If the motor’s getting power and the arm moves freely but the gate still won’t run, that’s a motor replacement conversation. Call (805) 516-0479 and we’ll schedule the diagnosis. The written estimate is free.
FAQs
Linear gate motors in Simi Valley typically last 7 to 10 years, though motors in full-sun exposures without shade can fail closer to 5 or 6 years from heat degradation of internal capacitors and winding insulation. If your motor is past year 8 and starting to struggle, planning for replacement now beats discovering the failure on a Monday morning.
Some failures are repairable – capacitors, limit switches, and even gear sets can be replaced on LRA series motors – but when the windings fail or the housing is corroded through, replacement is the parts-and-labor math that makes sense. We’ll show you the repair price and the replacement price on the same estimate so you can decide with real numbers. Call (805) 516-0479 for a free diagnosis.
A Linear gate motor replacement takes 2 to 3 hours for a direct swap, and up to half a day if the arm bracket or control board needs attention alongside the motor. Most jobs are same-day from diagnosis to tested-and-working, and you’ll have a photo log of the old motor, the new motor, and the limit readings before we pull out of the driveway.
We stock Linear-compatible motors for the LRA, APeX, and SL series on our trucks, along with aftermarket equivalents for the most common LRA models. We don’t stock every Linear part ever made – nobody does – but we carry enough to complete most Simi Valley replacements the same day we diagnose them.
