AfterLinear Gate Motor & Opener in Granada Hills: What to Know First
Linear gate motor and opener service in Granada Hills runs $185 to $440 for most repairs, and we typically have the gate running again same visit. We’re an independent Linear service provider, not a manufacturer warranty station, which means we fix what’s actually failing instead of quoting you a whole new operator. If you have a Linear gate motor acting up, dead, or halfway working, call (760) 361-6706 and we’ll tell you straight what it needs. This page explains how Linear operators fail in our part of the Valley, what honest repair costs look like, and why Granada Hills homeowners keep our number in their phone.
How Linear Products Fail — and How We Fix Them
- Linear LSO and LDO swing operators losing limit stops. These residential swing operators use mechanical limit cams that wear and drift over time, especially on heavy gates. The gate overshoots, then slams back against the post. We reset the limits, check the drive arm geometry, and replace the cam if it’s stripped. Fifteen minutes of adjustment beats a new motor every time.
- Linear SL and SLX slide operators cooking the start capacitor. Slide motors pull hard on startup, and the capacitor is the sacrificial part. A gate that hums but won’t move is almost always a dead capacitor or a seized drive bearing. We bench-test the motor, replace the capacitor and bearing if needed, and check the chain tension while we’re there. That last step matters because a slack chain is what killed the capacitor in the first place.
- Linear APeX control boards losing their programming. Power flickers and brownouts through the summer in Granada Hills are rough on control boards. The APeX board forgets its travel limits and the gate opens six inches and reverses. We re-flash the limits, replace the onboard battery, and note for you whether a whole-board replacement is coming or if the board still has years in it.
- Linear photoelectric safety eyes going dirty or out of alignment. The LX series eyes sit low and eat dust, sprinkler water, and the occasional garden hose spray. The gate refuses to close when the “beam” is broken. We clean the lenses, realign the eyes, and check the wiring at the J-box — and we’ll show you which eye is the culprit before we touch anything.
- Linear remote receivers not hearing the transmitter. The wire whip antennas on Linear receivers corrode where they enter the enclosure, especially on older Mighty-Mule-sourced boards. Range drops to eight feet and then nothing. We replace the antenna whip, re-secure the case with a proper gasket, and re-pair all your remotes. No board swap, no nonsense.
Our Linear Gate Motor & Opener Process
- 1
You call, a person answers. Hal or a member of his crew picks up, day or night. You tell us what the gate is doing — or not doing. We give you a straight idea of what we’re likely to find, and we schedule a time we’ll actually show up for.
- 2
We show up and look before we touch. We check the operator, the arm or chain, the hinges, the limit switches, and the board. Most Linear failures we see in Granada Hills are not the motor itself. It’s a limit cam, a capacitor, a bearing, or a board that lost its memory. We find the real failure before spending a dollar.
- 3
We quote the repair before we start. That’s the price on the table, part and labor, approved by you. You’ll see the same number on the invoice before any work begins. We don’t adjust it at the door.
- 4
We use OEM or proven aftermarket parts — with a reason for whichever we pick. For Linear control boards and safety eyes, we recommend OEM when the board is still in production, because aftermarket boards can fight the receiver logic. For capacitors, drive belts, and limit cams, a quality aftermarket part often outlasts the original at a lower price. We tell you which is which and why.
- 5
We fix it in your driveway. Welding is done on site — cracked operator mounting brackets, bent gate posts, broken hinge tabs, all handled without hauling your gate anywhere.
- 6
We test it like we own it. The gate cycles a dozen times, the safety eyes get blocked on purpose, the remote gets pressed from the street, and the limits get re-checked. Then we hand you our 90-Day Done Right Promise in writing. If it’s not right, one call brings us back.
What Linear Gate Motor & Opener Costs in Granada Hills
| Linear job | Typical cost |
|---|---|
| Limit switch reset and cam replacement | $185 – $260 |
| Start capacitor and bearing replacement (slide operator) | $220 – $310 |
| Control board replacement (APeX or legacy) | $310 – $440 |
| Safety eye replacement and realignment | $170 – $230 |
| Full operator replacement (swing or slide) | $1,100 – $2,400 installed |
What moves the price: age of the operator, whether the board is still made, how much welding the mounting points need, and whether the gate itself is dragging. A heavy gate with sagging hinges will eat a new motor in a year — so we fix the gate while we’re replacing the operator. Every estimate is free. You’ll always have the price approved before we turn a wrench. Call (760) 361-6706 for an exact quote.

FAQs
Linear was folded into Nortek Control and then Nice North America, so the name evolved, but most residential Linear operators still have parts available through aftermarket channels and some OEM warehouse stock. If your unit is under warranty, we’ll tell you before we start whether a factory claim makes more sense. As an independent service provider, our repair won’t void things — but we walk through the warranty picture honestly before any work.
In most cases, yes. We keep the common failure parts for Linear operators on the truck — capacitors, limit cams, drive arms, safety board components. Call (760) 361-6706 and we’ll give you a straight answer on timing. If it’s a full board replacement, we may need a day to source it.
Usually not. That’s most often the limit cam losing its stop position, or the board getting partial power. The motor is doing exactly what it’s told to do — it’s being told the wrong thing. We diagnose before we replace.
If the operator is under fifteen years old and the motor winding tests fine, repair almost always beats replacement. If the board is obsolete, the gearbox is grinding, and the arm is bent, replacement starts to make sense. We’ll show you the numbers either way — and we’ll never push a replacement when a $40 part fixes it.
Yes. We integrate Linear operators with gate intercoms and add or replace battery backup for the operators that support it. We’ll wire it clean, test it properly, and show you how it works before we leave.
