Linear Gate Motor & Opener in Agoura Hills: What to Know First
Linear gate motor and opener repair in Agoura Hills is work we do every week, and most jobs are diagnosed and repaired the same day we arrive. A typical Linear swing-gate motor replacement runs between $850 and $1,450, depending on the series and whether the arm bracket survived the failure. You get the written price before we pick up a tool, and you get the photo record before we leave. This page is for Agoura Hills homeowners with a Linear actuator, operator arm, or control board that has stopped doing its job. Call (424) 388-2906 and a live person answers.
How Linear Products Fail - and How We Fix Them
Linear builds the actuator that moves the gate, and the electronics that tell it when to move. When they fail, the failure usually leaves evidence. Here are the five we see most often on Agoura Hills driveways.
- Linear LRA and LA series actuator arm: capacitor death after a hot summer. The LRA linear ram and the older LA412-style arms use a motor start capacitor that sits inside a housing with almost no ventilation. After several Agoura Hills summers with temperatures in the 90s and direct afternoon sun on the arm, the capacitor dries out and the motor hums but does not move. The fix is a new capacitor with a higher temperature rating than the OEM part, and we photograph the old one with its bulged casing before it goes in the bin.
- Linear APeX controller: ghost operation from a corroded edge sensor terminal. The APeX board is sensitive to moisture at the safety-edge input terminals. Coastal air off the Santa Monica Mountains puts enough humidity into an unsealed enclosure to start corrosion within a few years. The gate opens or stops for no reason, or refuses to close. We pull the board, clean the terminal block with contact cleaner, reseal the enclosure, and document the before and after. If the terminal is too far gone, we install a sealed terminal strip rather than replacing the whole board.
- Linear M3 and M5 slide-gate operators: limit switch drift on long runs. On longer driveway runs, the mechanical limit switches on the M3 and M5 slide operators can drift a few degrees with repeated use. The gate starts slamming into the end stop or stopping short of fully open. We reset the limit positions, torque the cams, and record the exact limit positions in the job notes so the next adjustment is a five-minute job instead of a re-diagnosis.
- Linear Delta-3 and PB series remotes: receiver board failure from voltage spikes. The receiver on the Delta-3 receiver board and the PB-series remotes paired with it can burn out after a minor power surge. The homeowner still hears the transformer hum, but the board no longer responds to any transmitter. We test with a known-good remote before condemning the board, then install a surge protector on the power feed so the replacement does not meet the same end.
- Linear gate openers with battery backup: charger failure masquerading as a battery failure. When a Linear system with battery backup stops working during a power outage, most people replace the battery. In our experience on Agoura Hills installs, the charger board fails first and the battery is fine. We test the charger output before recommending any battery replacement. A constant 13.8 volts is normal; anything under 12.9 means the charger is the problem.
Our Linear Gate Motor & Opener Process

- 1
Call comes in. You reach a live person, not a voicemail menu. We ask what the gate is doing, what the model plate says, and whether the remote or keypad still works at all.
- 2
Dispatch and arrival. A background-checked technician arrives in uniform, introduces himself by name, and starts with a visual inspection: the arm, the mounting, the wiring, the operator enclosure, the photo-eyes, the safety edges.
- 3
Diagnostics and documentation. We test voltage at the board, check the capacitor with a meter, watch the limit cycle, and photograph every finding. If we find the problem, we show you what we found before we touch anything.
- 4
Written price. Before any work starts, we hand you the flat price in writing. That is Haven Standard Clause 1, and we do not skip it. The price covers parts and labor, and it does not change at the end.
- 5
Repair and test. We install OEM Linear parts where the warranty matters, and quality aftermarket where the OEM part is the weak point (the capacitor being the usual example). We cycle the gate multiple times, test the safety reversal, and check the photo-eye alignment.
- 6
Closeout and record. Before we leave, you get a photo log of every adjustment, a written record of every part number installed, and a one-year guarantee on the work. That is the 365-Day Done Right Promise.

AfterWhat Linear Gate Motor & Opener Costs in Agoura Hills
Here is what we typically write on the estimate sheet for Linear work in Agoura Hills. These are real ranges from jobs we have done, not list prices from a catalog.
- Linear swing-gate actuator replacement (LRA or LA series): $850-$1,450, depending on arm length and whether the mounting bracket is reusable.
- APeX control board replacement: $450-$750, including programming and safety-edge re-verification.
- Capacitor replacement on a Linear arm: $120-$220, including the upgraded high-temp part and the photo record.
- Limit switch reset and tune-up on M3/M5 slide operators: $150-$300.
- Full Linear slide-gate operator replacement (M3/M5 class): $1,800-$2,800, depending on gate length, weight, and whether the power feed needs upgrading.
What moves the price: the specific Linear series on the property, whether the mounting plate survived, and whether the power at the gate is clean or needs a surge protector added. You will know the exact number before we start, because we write it down and hand it to you. Call (424) 388-2906 for a free estimate.
Why Agoura Hills Homeowners Call Vance Gate Repair Agoura Hills for Linear Work

We carry Linear parts and know the weak points without guessing, which means you are not paying us to learn on your driveway. We are an independent Linear service provider, so we can tell you frankly when an OEM part is the right call and when a better aftermarket part exists. And if the motor on your property is not a Linear, we service LiftMaster, Mighty Mule, Ghost Controls, and DoorKing as well, so you do not need a different phone number for every brand. Every visit leaves a documented record under Clause 4 of The Haven Standard: what we found, what we set, what we installed. Adrian Vance started doing this kind of documentation on commercial access-control sites back in 2014, and he has not stopped. Name what you found. Name what it costs. Name what you left behind.
FAQs
Yes, we work on Linear gate openers under warranty, but as an independent Linear service provider, the warranty is between you and Linear. Our work does not void it; we use OEM parts where the warranty depends on it, and we document everything so you can submit a claim with a clean record. Call (424) 388-2906 and we will walk you through what the warranty likely covers before we schedule anything.
In most Agoura Hills cases, yes. We stock the common Linear repair parts and the call-out itself usually happens the same day you phone. Capacitor replacements, limit resets, and remote programming are almost always one-visit fixes. If the operator requires a part we need to order, we tell you that before you commit to anything. Call (424) 388-2906 and we will give you an honest arrival window.
If the arm moves and the board responds, repair is usually the right call. We see Linear arms that are twelve years old with no issues past the capacitor, and replacing the whole operator would cost you four times as much for no benefit. If the gear train is worn to the point of slapping, or the board has failed in multiple zones, we will tell you that too, with the pricing for both paths on the table. The estimate is free and the decision is yours.
Yes. We program Delta-3, PB-series, and other Linear transmitters, replace receiver boards, and sync keypads to existing operators. We also test the receiver before we blame the remote, because the receiver board fails more often than the remote does on Agoura Hills properties with older Linear installs.
A full Linear operator installation includes mounting, power connection, limit setting, safety device wiring and testing (photo-eyes and safety edges), remote and keypad programming, and a documented closeout with photos and part numbers. We quote the full installation in writing before any work starts. Call (424) 388-2906 to schedule a free on-site measure and written estimate.
