Linear Gate Motor Replacement: The Sherman Oaks Owner’s Guide
Most Linear gate motors in Sherman Oaks run between 8 and 14 years before the internal gears or the main control board gives out. A full replacement, installed, typically lands between $650 and $1,100 here depending on which Linear model you have and whether the old wiring can stay. We stock Linear-compatible motors and parts on the truck, so in most cases the swap happens the same day we come out.

You usually notice it’s dying before it’s dead. The gate starts lazy on cold mornings. It groans halfway across the track. The remote works when you’re ten feet away but not when you’re in the car at the curb. Then one evening it just sits there, humming or completely silent, and you’re parking outside and walking to the house. That’s the moment most people in Sherman Oaks call us.
Key Takeaways:
- Linear motor replacement in Sherman Oaks typically runs $650-$1,100 installed
- We keep Linear-compatible motors and boards on the truck for most common models
- Same-day replacement is available when the old wiring is in good shape
- Every job includes the 90-Day Done Right Promise in writing
Which Linear Models This Applies To
Linear made a lot of gate operators over the years, and the model number on the old unit matters more than you’d think. The LDO series (LDO50, LDO33) is the one we see most often on swing gates in Sherman Oaks. The Linear SW series and the older Linear RB/GRB residential units show up on slide gates, especially on the wider lots up around Valley Vista Boulevard and the hillside properties near Mulholland.
Here’s the compatibility gotcha with Linear: the blue control board inside changed pin layouts across model years, even within the same series. You can’t just match a motor by horsepower. You need the exact model number off the label, or at minimum a clear photo of the control board and the gear housing. We ask for both when you call. It saves a second trip.
On OEM versus aftermarket: Linear is now owned by Nortek, and genuine Linear replacement parts have gotten slower to source and pricier over the years. For most residential installations, we recommend the OEM board when we can get it quickly, and a quality aftermarket motor from brands like All-O-Matic or GBD when we can’t. The aftermarket motors we use carry a comparable lifespan and we back the entire installation with our own promise either way. We’re an independent shop, not affiliated with Linear, so we’re free to pick whichever part actually serves you best.
Signs Your Linear Gate Motor Replacement Is Failing
- Humming but not moving. The motor is getting power and trying, but the plastic drive gears inside have stripped. Common on LDO models that are 10+ years old, especially after a power surge. This is a mechanical failure, not a wiring problem, and it means the motor assembly needs replacing.
- Remote works intermittently, and only from close range. The receiver board is slowly failing. Sometimes it’s the board on the motor, sometimes it’s interference from all the Wi-Fi congestion in a dense Sherman Oaks neighborhood. We test before we recommend the full motor swap.
- Gate opens fine but slams shut or closes at half speed. The limit switch logic on the board is no longer reading position correctly. Left alone, this beats the hinges and hinge post until the whole gate sags, and then you’ve got two repair bills instead of one.
- Tripped breaker or GFCI repeatedly. The motor is drawing more current than it should, usually because the internal armature is wearing out or the capacitor is failing. Don’t keep resetting it; that’s the motor telling you it’s done.
- Obvious water or ant damage inside the cover. Sherman Oaks gets more moisture than people expect, and Linear housings aren’t perfectly sealed. Ants love the warmth inside a control box. Both will take a board out quietly.
Replacement Cost & What’s Included
In Sherman Oaks, an installed Linear gate motor replacement runs $650 to $1,100 for most residential single-family models. Here’s how that breaks down:

- Motor or board assembly: $280-$520 depending on model and whether we use OEM or quality aftermarket
- Labor to remove, mount, wire, and set limits: $220-$380 for a standard replacement without complications
- Wiring or post repair (if needed): $75-$250, only when the old wiring or mounting plate is compromised
The range depends on three things: which Linear model you have, whether the old wiring can stay, and whether we’re reusing your existing receiver or installing a new one. The biggest driver is the model year of your old board. Older boards sometimes require a retrofitted harness to pair with a new motor. The cost is quoted and agreed before any work starts; you’ll know the exact number before we touch a single wire. And every replacement carries our 90-Day Done Right Promise in writing. No fine print, no “up to.” If it’s not done right, we make it right.
DIY or Call Us?
You can verify a few things safely before calling: check that the breaker isn’t tripped, make sure the gate itself moves freely by hand when it’s disengaged, and look for obvious water or rodent damage inside the cover. Those take ten minutes and they help us help you faster.
Replacing the motor itself is a different matter. A gate motor runs on 110V or 220V at the terminals, and setting the limits, force, and safety edges on a moving gate is not like swapping a light fixture. We have been called out to more than one Sherman Oaks driveway where a homeowner got the motor mounted, wired it in reverse, and then the gate pinned the car against the fence post. A gate can break bones. If you’re not sure, don’t guess. Call (818) 873-5061 and Hal or one of his crew will come look. Estimates are free, and we’ll tell you plainly if the motor is the problem or something cheaper is.
FAQs
Most Linear gate motors in Sherman Oaks last 8 to 14 years. The coastal-adjacent moisture and summer heat up here shorten the lifespan of the control boards more than the motors themselves, and many units die from board failure with a perfectly good motor attached. That’s half the reason model-year matching matters.
Sometimes. If the failure is a capacitor, fuse, relay, or replaceable gear, we repair it for less than a full motor swap. If the armature or gearing is seized or the board is cooked, replacement is the honest call. We’ll show you the part before we recommend either path. Call (818) 873-5061 and we’ll give you a straight answer.
A standard Linear motor swap on a residential gate takes between one and three hours on site. If the old wiring and mounting plate are in good shape, it’s usually a one-visit job. We carry common Linear motor assemblies and boards on the truck, so we’re not waiting on a delivery.
We stock Linear-compatible motors, boards, receivers, and remotes for the most common residential models on the truck. For less common Linear variants, we can usually have the part in hand within a few business days. We also keep parts for LiftMaster, Mighty Mule, and Ghost Controls systems. Call (818) 873-5061 with your model number and we’ll check the truck before we even schedule.
If you’ve got a Linear gate that’s humming, slowing down, or just quit last night, give Hal a call. You’ll get a straight answer, a real price, and if it makes sense, a same-day swap. No voicemail, no runaround. Call (818) 873-5061 for a free estimate. And if Hal doesn’t pick up, he’s probably under a gate. He’ll call you back before the hour’s out.
