Linear electric gate repair in Orange County typically runs $165 to $580 depending on what failed, and most single-part repairs are completed the same visit. We’re an independent Linear service provider, not a manufacturer-authorized shop, which means we stock and source both OEM and quality aftermarket parts without the dealer markup or the scheduling delay. If your Linear opener is dead, grinding, or opening halfway and reversing, call (820) 529-0801 and we’ll give you a written price before any work starts.

This page is for homeowners and property managers in Orange County who own a Linear swing gate or slide gate system and need a straight answer about what’s wrong and what it costs to fix. No gate jargon without the plain-English translation, no phone-tree runaround, no invoice surprises at the end of the day.

How Linear Products Fail – and How We Fix Them

Linear operators are common across Orange County, especially the LRA and APeX series on residential swing gates and the SL series on slide gates along the ranch properties in Trabuco Canyon and Coto de Caza. They’re generally solid machines, but every line has its known weak spots. Here’s what we actually see in the field.

  • LRA series swing-gate actuators: seized or stripped limit cams. The LRA actuator, which is the motorized arm that physically pushes the gate open, uses mechanical limit cams that set where the gate stops. After a few years of coastal salt air near Laguna Niguel or Dana Point, those cams corrode and the gate overshoots, stalls against the post, or slams at the end of travel. We pull the actuator, free or replace the cam assembly, reset the travel limits, and the gate runs like it should.
  • APeX series control boards: damaged relays from low-voltage shorts. The APeX board is the brain of the system, and its relays are the usual casualty when a low-voltage wire rubs through on a hinge side or a gate loop gets nicked by a weed trimmer. The gate may open but not close, or the opener hums and nothing moves. We trace the short first, then swap the relay or the board, because replacing a board without fixing the short just means replacing the board again in three weeks.
  • SL series slide gates: stripped drive gears and compromised rack-and-pinion spacing. The SL series uses a steel rack bolted to the gate and a pinion gear on the motor to move it. A gate that has settled a quarter inch in the wrong direction forces the gear teeth to take the load instead of the wheels. We see chipped pinion teeth and a chattering slide on gates that haven’t had a fabricator check the track spacing in years. The fix is often a new drive gear plus re-shimming the rack to the motor’s gear pitch.
  • Linear remote controls: phantom draining and dying transmitters. Older Linear multi-button remotes are power-hungry. We’ve had Anaheim Hills customers whose remotes were dead after two weeks because the transmitter sat in a drawer where a button was compressed. Before you buy a third remote, we check for a stuck key, verify the receiver frequency, and if the remote is truly bad, we program a replacement on the spot.
  • Safety sensor failures: misaligned photo eyes and dead-edge transmitters. Linear photo eyes and wireless safety edges are the two most common reason a gate reverses immediately or refuses to close at all. On APeX and LRA systems, a photo eye that has drifted slightly out of alignment or been splashed with irrigation water will read an obstruction that isn’t there. We realign, clean, and dielectric-grease the connections, and if the sensor is genuinely failed, we install a new one rather than jumping the circuit to make the gate close.

Our Linear Electric Gate Repair Process

Every Linear job follows the same shape, whether it’s a dead control board in a Newport Coast driveway or a grinding actuator in Yorba Linda. You’ll know where you stand at every step, because the price is written down before we touch a bolt.

  1. 1
    You call and describe the symptom. A live person answers, day or night. We ask what the gate is doing and what model you have if you know it. That tells us which parts to bring.
  2. 2
    We arrive in the window we gave you. Our technician is background-checked and in uniform. We identify ourselves before we set foot on the property.
  3. 3
    We diagnose and write the price down. We test the input power, safety edges, limit settings, and operator mechanics in front of you. Then we hand you a written price for the repair, parts and labor, before any work starts.
  4. 4
    We make the repair with the right parts. For Linear systems, we use OEM parts where warranty or board compatibility demands it, and quality aftermarket equivalents where the OEM item is backordered or overpriced. We tell you which one we’re using and why.
  5. 5
    We test under load and through multiple cycles. The gate gets cycled with the safety edges tripped, the photo eyes blocked, and the remote range verified from a moving vehicle. We don’t call it done until it handles normal use without a hiccup.
  6. 6
    You receive a written Kingswell Guarantee on the repair. The repair is guaranteed in writing for 365 days. If it fails inside a year, we come back and correct it at no charge. Then we leave your driveway cleaner than we found it.

What Linear Electric Gate Repair Costs in Orange County

Here’s where we give you the numbers most gate companies keep vague. The final tab depends on the machine, the part that failed, and whether we’re working on a residential swing gate in Fullerton or a high-cycle commercial slide gate off the 55. But these ranges hold for most Linear single-part failures across Orange County.

  • Linear LRA actuator replacement (swing gate): $390 to $720 parts and labor. The actuator, plus resetting the limit cams and checking the hinge and post alignment.
  • Linear APeX control board replacement: $210 to $480 parts and labor, depending on whether it’s a single or dual gate board, and whether a relay swap will suffice instead.
  • Linear remote control or keypad replacement and programming: $95 to $240, including programming all existing transmitters. We do not charge a “reprogramming fee” for the remotes we just installed.
  • Safety photo eye or edge sensor repair: $165 to $380. Realignment alone is often less, a new wireless edge kit is more.
  • Slide gate rack-and-pinion repair (Linear SL series): $310 to $650, depending on how much track realignment is required.

What moves the price: seawater proximity, gate weight on undersized actuators, wire runs that were never inspected, and whether the last technician left the safety circuits bypassed. We’ll tell you which applies to your gate before we quote. Call (820) 529-0801 for an exact number in writing. Estimates are free.
