Linear Gate Motor & Opener in Los Angeles: What to Know First
Linear gate motor and opener repair in Los Angeles typically runs $180 to $480 for a service call and common fixes, and a full motor replacement usually lands between $650 and $1,400 depending on the model and how much of the old wiring we need to sort out. Most Linear jobs are done same-day or next-day once we’ve seen the gate, because we keep the common Linear parts on the truck and weld on site. You’ll know the price before we turn a wrench, and it won’t change at the door.
This page is for homeowners and property managers across Los Angeles who have a Linear opener that’s grinding, stalling, or just quit. If that’s you, call (877) 610-2993 and you’ll get a live person, not a recording. Hal Gatewood has been working Linear equipment around this city since 2001, and he’ll tell you straight whether it’s worth fixing or time to replace.
How Linear Products Fail - and How We Fix Them
Linear builds solid openers, but every brand has its habits. Here are the ones we see on gates all over Los Angeles:
- Linear LSO/OSCO slide gate operators with limit switch drift. These are common on apartment buildings and commercial lots around South LA and the Valley. What we find is the mechanical limit cam wears just enough that the gate over-travels and slams the end stop, which eventually cracks the drive rail. The fix is resetting the limits, replacing the worn cam, and checking the rail alignment, not just clearing the error code.
- Linear APeX and MegaCode receivers that lose their memory after a power blink. LADWP outages or a brownout on a hot August afternoon can wipe the transmitter codes. We reprogram the receiver, add a small battery backup where the homeowner wants one, and test every remote on site so nobody is left standing at the call box.
- Linear swing-arm openers on hillside driveways dragging in late summer. This is a Los Angeles geography thing. When the ground dries out in August and September, gate posts in areas like Mount Washington or the Hollywood Hills shift a fraction of an inch, and a Linear arm that was fine in February starts binding. We realign the post or shim the arm bracket rather than forcing the motor to fight the ground.
- Linear DC motor boards with dead capacitors after a surge. The modular DC units (the LDCO and similar) are sensitive to voltage spikes, which we get plenty of during Santa Ana wind events when lines arc. We replace the capacitor or the control board, not the whole motor, and we check the surge protection so it doesn’t happen again in November.
- Gearbox wear on older Linear slide motors that were never greased. Linear’s slide operators have a gear reduction that a lot of installers never service. After five or six years in Los Angeles dust and heat, the grease turns to paste and the gears wear. We clean and regrease on site, and only replace the gear set when the teeth are actually gone.
Our Linear Gate Motor & Opener Process
Every Linear job we do in Los Angeles follows the same routine, whether it’s a small residential swing gate or a slide gate on a commercial driveway. No shortcuts.
- 1
You call, a person answers. We ask what the gate is doing, what model you see on the opener, and when it started. That tells us what parts to bring.
- 2
We come out and look at the whole gate, not just the motor. A Linear opener pulling too many amps is usually fighting a hinge, a wheel, or a sagging post. We find that first.
- 3
We give you the price before any work. You’ll know the number, and it’s what you pay. If it’s a small fix, we do it right there. If it needs parts, we tell you when we’ll be back.
- 4
We make the repair with the right components. For warranty-sensitive parts, we use Linear OEM. For things like batteries or solar panels where aftermarket is just as reliable and costs less, we say so and let you decide.
- 5
We run the gate through full cycles, test every remote, and check the safety edges and photo eyes. Then we watch it run with you standing there, so you see it work before we leave.
- 6
You get the 90-Day Done Right Promise in writing. If something isn’t right, one call brings us back. No runaround, no fine print.

Why Los Angeles Homeowners Call Gatewood Fence & Gate for Linear Work
Hal Gatewood has been working gates in Los Angeles since 2001. He grew up in the San Fernando Valley and learned the fundamentals at Los Angeles Trade-Technical College downtown, then spent enough years in driveways and alleys to know which Linear models hold up and which ones repeat the same failure every few years. That matters when you need a real diagnosis instead of a parts cannon.
We are an independent Linear service provider, not a manufacturer shop, so our only interest is what actually fixes your gate. Every job carries the 90-Day Done Right Promise, the person who shows up knows Linear equipment, and if your system is truly done for, we service LiftMaster, Mighty Mule, Ghost Controls, and DoorKing as well, so you’re never stuck. And when you call at two in the morning because your gate won’t close and your dog is loose, the person who answers is here in Los Angeles, not a call center three states away.
FAQs
Yes, in most cases we can repair a Linear gate motor the same day or next day once we see the gate, because we keep common Linear parts on the truck and do our welding on site.
No, using an independent service provider does not void a Linear warranty, and for warranty-sensitive components we install Linear OEM parts so everything stays compliant.
If the motor’s armature or gearbox is shot and the opener is more than 12 years old, replacement usually makes more sense than repair, but we’ll tell you the real numbers for both before you decide.
It depends heavily on how well they were installed and maintained, but we’ve seen Linear motors in Los Angeles run reliably for 10 to 15 years when they were greased and aligned properly from day one.
Yes, we wire and program Linear-compatible intercoms, call boxes, and keypads as part of gate motor and opener work, including older APeX and MegaCode receiver systems.
