Linear Gate Motor Replacement: The Malibu Owner’s Guide
A Linear gate motor replacement in Malibu typically runs $420 to $680 installed, and we keep the most common Linear replacement parts on the truck so we can usually handle it the same day we look at it. That price covers the motor, the gear assembly where needed, and the labor to swap it, test the limits, and make sure the gate closes square. Most folks find out their Linear has failed the same way: the gate starts moving slower than it did last month, then it’ll sit there and hum without budging, then one morning it just doesn’t respond at all.

What you’re describing if you’ve landed here is usually one of two things. Either the motor itself has given up after years of salt air and daily cycles out on the coast, or the gear train inside the operator has stripped and is spinning without catching. Both are fixable. Neither requires you to rip out the whole gate system and start over, which is what a national outfit will sometimes tell you because it’s an easier upsell than a repair.

Which Linear Models This Applies To
The Linear name covers a lot of ground, because the company made gate operators under several lines over the years. The ones we see most often on Malibu driveways and ranch gates are the Linear LDO series (the LDO50 and LDO33 are everywhere), the ACT series, and the older APeX units that are now fifteen-plus years old and showing their age. The key to ordering the right motor replacement is the model tag on the side of the operator chassis, not the arm or the control board. Write down everything on that tag and send us a photo of it, and we’ll match it before we leave the shop.
Here’s the compatibility gotcha that catches people: a Linear LDO50 motor does not drop into an LDO33 housing, even though they look nearly identical from the outside. The shaft length and mounting pattern differ between the two. Same story with certain ACT models built before 2008. We’ve also seen aftermarket motors advertised as “fits all Linear swing gate openers” that are about as universal as a square peg. We stock genuine Linear OEM replacement motors where they’re still available, and we carry a short list of aftermarket equivalents we’ve tested and will actually stand behind. If we wouldn’t put it on our own gate, it doesn’t go on yours. Gatewood Fence & Gate is an independent service provider, not affiliated with Linear, which means we tell you straight what your options are instead of steering you toward whatever’s in stock this quarter.
Signs Your Linear Gate Motor Replacement Is Failing
- Gate hums but doesn’t move. That’s almost always the gear train stripping. The motor’s spinning fine; the plastic or composite gear inside the operator is what gave up. On Linear units the gear is the sacrificial part, and it’s a fraction of the cost of a full motor swap.
- Gate moves noticeably slower than it used to. On a swing gate that started its life taking twelve seconds to open and now takes twenty, the motor windings are tired or the capacitor’s weak. In Malibu we see this a lot on exposed coastal properties where the unit runs in salty air ten months a year.
- Operator trips its internal breaker or pops the GFCI. This points at the motor pulling more amperage than it should, usually from internal wear or moisture intrusion. Don’t keep resetting it: every trip is the motor telling you it’s done.
- Gate only moves when you give the arm a push. That’s the motor’s start winding gone. It’ll struggle to start under load and fail completely on a cold morning. We replace the motor rather than nursing it along.
- Burnt smell from the operator housing. That’s lacquer burning off the windings inside the motor. Once you smell it, the replacement clock’s already run out. Shut the unit off at the breaker and call us.
Replacement Cost & What’s Included
Here’s the honest math for a Linear gate motor replacement in Malibu. The motor assembly itself runs between $180 and $320 depending on your model and whether the gear needs replacing at the same time. Labor typically lands between $240 and $360, which includes removing the old unit, installing the new motor, setting the open and close limits, adjusting the force settings, and cycling the gate ten or twelve times to make sure it behaves. Total installed price: $420 to $680 for most single-gate Linear operators.
| Item | Typical Range |
|---|---|
| Linear replacement motor (OEM) | $180 - $260 |
| Gear assembly (if stripped) | $60 - $110 |
| Labor, testing & setup | $240 - $360 |
| Typical total installed | $420 - $680 |
You’ll hear a quoted price before we touch the gate, and that price is what you’ll pay. No trip charge inside the county, no surprise line items. If the gate needs an additional part we didn’t see coming, we walk over and show it to you before we do anything. Every job carries our 90-Day Done Right Promise in writing, so if the new motor acts up in the first three months, one call brings us back. And we offer a free second opinion on any written estimate from another company, which has saved more than a few Malibu folks from paying for a full replacement they never needed.

DIY or Call Us?
You can safely check a few things yourself. Confirm the unit has power at the outlet, check that the breaker hasn’t tripped, and open the cover to see if there’s obvious moisture or an ant nest inside. Those are real culprits out here, and they cost nothing to rule out. What you should not do is start unbolting the motor from a Linear operator and wiring in a replacement you found online. This is line-voltage work, and the capacitor inside holds a charge even after the unit’s unplugged. A wrong wiring match between the motor leads and the control board turns a $500 repair into a $1,400 control board replacement. We’ve had to fix that exact sequence more times than I’d like. If you’ve narrowed it down, tell me what it’s doing wrong and I’ll tell you what it actually needs - no runaround. Call us at (559) 314-7708 and we’ll get eyes on it.
FAQs
A Linear gate motor in Malibu’s salt air typically lasts 8 to 12 years, though units within a half mile of the ocean often fail closer to the 6- to 8-year mark because the wind-driven salt mist eats at windings and board connections. If your gate opens and closes 20-plus times a day, knock another couple years off. Call (559) 314-7708 if yours is acting up and you want a straight answer on whether it’s worth replacing the motor or the whole operator.
Rarely. Once windings burn, the motor’s done. What can be repaired on a Linear that’s humming or running rough is the gear train and the capacitor, both of which are far cheaper than a motor swap, so we always check those first. If the motor itself is the problem, replacement is the repair. Call (559) 314-7708 and we’ll verify which one it actually is.
Most Linear gate motor replacements take 90 minutes to 2 hours on site. If we have your model tag ahead of time, we’ll arrive with the right motor on the truck and get it done in one visit. If the gear needs replacing too, add another 30 minutes.
We keep the most common Linear replacement motors and gear assemblies on the truck, including parts for the LDO33, LDO50, and the older APeX series. Less common models usually arrive at our shop within two business days. We also carry parts for LiftMaster, Mighty Mule, and Ghost Controls if that’s what’s on your gate instead. Call (559) 314-7708 and we can tell you over the phone whether yours is already on the truck.
