Linear Gate Motor Replacement: The Agoura Hills Owner’s Guide
A Linear gate motor replacement in Agoura Hills typically runs $850 to $1,650 installed, depending on the model and whether the arm, brackets, and control board are still sound. We stock Linear-compatible motors and parts on our trucks, so most replacements are done in a single visit, usually within two hours of arrival. The way most Agoura Hills homeowners discover they need this is simple: the gate gets halfway open, groans, and stops, or the motor hums without moving anything, or the whole thing went silent overnight after a hard rain. You’re not imagining it. These motors work hard in our climate, and when they go, they tend to go in stages, not all at once.
Which Linear Models This Applies To
If your gate operator has a Linear nameplate, you’re most likely dealing with an LDO series slide operator, an LS series swing operator, or the old APeX and M3 lines that Agoura Hills homes have run for fifteen to twenty years. The motor inside is the workhorse, and the single most common gotcha we see is a homeowner buying a replacement online for an LS model and discovering it doesn’t match the arm geometry of the older M3 that’s actually on the gate. The model number is printed on a silver tag on the side of the motor housing; if that tag is sun-faded or missing, measure the bolt spacing on the motor mount face, because among Linear models, the spacing changes between series and a motor that’s off by half an inch will not seat. None of this is guesswork for us. Linear has been one of the nine brands we service for years, and we keep both OEM and quality aftermarket motors in stock, along with the boards, arms, and capacitors that fail alongside them. One more thing worth knowing: Linear, as a brand, has gone through ownership changes that left some older part numbers discontinued. A quality aftermarket equivalent is often the smarter buy than chasing a $600 OEM motor for a twenty-year-old opener. We will tell you which is which before you spend a dollar.
Ironworks Gate Co. is an independent service provider. We are not affiliated with Linear, LiftMaster, Mighty Mule, Ghost Controls, or any of the brands we service. We simply know their equipment well enough to fix it correctly the first time.
Signs Your Linear Gate Motor Replacement Is Failing
Most Linear motor failures follow a pattern. Here’s what owners in Agoura Hills tell us they noticed before the gate stopped entirely:
- Humming with no movement. The motor gets power and tries to start, but the starter capacitor has failed or the gears have stripped. We replace both together, because a new motor on an old capacitor burns out within months.
- Gate stops midway and reverses. The motor’s internal current sensing is tripping because it’s drawing too much power. That’s usually a motor running with a failing bearing along the Ladyface foothills grit and heat, not a limit switch problem.
- Intermittent operation after rain. Moisture creeps into the housing through a dried seal, and the motor runs on damp windings until it shorts. Agoura Hills winter rains catch a lot of these before the motor dies outright.
- Screeching or grinding on startup. The internal gear train is eating itself. Running it longer only turns a $900 motor replacement into a $1,600 full operator replacement.
- The gate is hard to push manually, even with the operator disengaged. The motor isn’t the problem here, it’s a symptom of seized hinge or wheel bearings forcing the motor to work double. We address the root cause so the new motor isn’t doomed on day one.
Replacement Cost & What’s Included
For an Agoura Hills home, you’re looking at $850 to $1,650 for a complete Linear motor replacement, including the motor, labor, and whatever small hardware the job needs. A straight motor swap on an LDO slide operator sits at the lower end. Replacing a swing-arm motor along with the arm and board runs toward the higher end. The variance is driven by model age, access to the operator, and whether the control board and receiver should be replaced at the same time. We quote the full job price up front and we agree on the number before we turn a single bolt. No surprises on the bill. Every motor we install carries our written 90-Day Done Right Promise, which means if it isn’t right, we come back and make it right. No paperwork, no arguing.
Key takeaways:
- Installed Linear motor replacement in Agoura Hills: $850-$1,650
- Price quoted and agreed before any work starts
- Parts on the truck for most Linear LDO and LS series operators
- Written 90-Day Done Right Promise on every job
DIY or Call Us?
Here’s the honest split. You can safely check the basics: is there power to the outlet, is the breaker tripped, is the manual release lever fully seated. These take five minutes and cost nothing. Beyond that, this is a job where DIY goes sideways fast. A Linear gate motor involves 120-volt or 240-volt wiring, springs and arms under tension, and a heavy gate leaf that can crush a hand if the operator releases unexpectedly. If the gate is a slide gate, the motor and chain or belt drive sit at waist height with pinch points all around. The smart move is to call us at (213) 293-3886. If it rolls or swings, we can sort it out, and we will tell you exactly what we found before we touch a thing. Victor Salinas grew up in the Ladyface foothills, and half the driveways on his street had a gate that needed attention at least once a year. He’s been straight with homeowners about what a gate actually needs versus what it doesn’t for the better part of three decades. We’ll give you the same honesty.
FAQs
A Linear gate motor installed in Agoura Hills typically lasts 8 to 12 years, though salt air drifting in from the coast and our summer heat against the foothills can shorten that to 6 or 7 years without regular service. The motor itself usually outlives the capacitor and the gear train, which is why we replace those together at motor swap time. Call (213) 293-3886 and we’ll assess what’s actually worn on your operator.
The motor itself is almost never rebuilt, because opening the sealed housing to replace armature bearings costs more in labor than a quality replacement motor. But the parts that fail around the motor, the capacitor, the limit switches, and the drive gears, are very repairable, and sometimes that’s all the gate needs. We’ll tell you which one it is before you spend anything at all. Call (213) 293-3886 for a straight answer, free.
Most Linear motor replacements on LDO and LS series operators take about two hours from the time our technician starts to the time the gate cycles smoothly on its own. The work includes removing the old motor, mounting the new one, setting the limit switches, and adjusting force so the gate closes without slamming. Book at (213) 293-3886 and we’ll schedule a window we stick to.
We stock Linear-compatible motors and the supporting parts on our trucks, so you don’t have to gamble on an online purchase that may not match your series. We also service the other brands you might have on the driveway, including LiftMaster, Mighty Mule, and Ghost Controls. If a specific motor is not on the truck for a less common model, we source it from our local supply houses same or next day. Either way, call (213) 293-3886 first and we’ll tell you what you actually need before you order anything.
