We provide independent Linear electric gate repair in San Jose, and most jobs are completed in a single visit once the failure is diagnosed. Our technicians arrive with the common Linear control boards, actuators, and sensor hardware on the truck, which means you’re not waiting a week for a part to ship. As an independent Linear service provider (we’re not affiliated with or authorized by Linear), we give you the written price before any work starts, and every repair is covered by the 365-Day Done Right Promise. If you own a Linear gate that won’t open, hums but doesn’t move, or trips its sensors when nothing’s in the way, call (669) 800-5686 and a live person picks up.
How Linear Products Fail – and How We Fix Them
Linear operators the brand’s swing-arm and slide-gate models share a few failure patterns we see regularly across San Jose neighborhoods like Almaden, Evergreen, and the Rose Garden area. Here are the five we diagnose most often.
- Linear Slide Gate Operator (SL-Series): limit switch drift. On the SL slide operators, the mechanical limit switches that tell the gate where to stop gradually work loose from vibration. The gate starts stopping short, or over-travels and slams the end stop. We see it most on gates that cycle fifty or more times a day. The fix is re-seating and re-setting the switch cam, and we always check the mounting hardware so it doesn’t drift again in six weeks.
- Linear Swing Gate Operator (SW-Series): capacitor failure on the actuator arm. When a Linear swing arm hums but won’t push the gate, the start capacitor in the operator is usually the dead component. San Jose’s summer heat shortens capacitor life, and homeowners who park near open southern exposure see this more than shaded Rose Garden properties do. We test the capacitor under load, not just for continuity, because a weak capacitor will pass a simple meter check and still fail to start the motor.
- Linear Control Board (APeX and MegaCode series): relay contact burn. The relay that powers the motor opens and closes thousands of times, and eventually the contacts pit. Symptoms are intermittent operation, or a gate that opens but won’t close without a manual reset. On the APeX boards we replace the relay rather than the whole board when the rest of the circuit tests clean, which keeps the repair well under board-replacement cost. If the board has burn marks beyond the relay, we recommend a full board swap and we’ll show you the damage before you approve it.
- Linear Photo Eye and Edge Sensor: false trips in wet weather. Linear safety edges and photo eyes are low-voltage circuits, and a nick in the edge sensor’s rubber housing lets moisture in during San Jose’s winter rain season. The gate reverses for no reason, or refuses to close at all. We test the sensor loop with the gate stopped, then isolate which edge or eye is causing the false trip before replacing anything.
- Linear MegaCode Receiver: remote range collapse. When a Linear remote only works from ten feet away, the receiver’s antenna or the coaxial connection has usually failed, or a new nearby device is flooding the MegaCode frequency. We tune the receiver, replace the antenna, and in a few Almaden Valley cases we’ve relocated the receiver away from a new solar inverter that was drowning the signal.
Styles & brands we work with





Our Linear Electric Gate Repair Process
- 1
You call, a person answers. We ask what the gate is doing or not doing, and when it started. That gives the technician a head start on diagnosis before he’s even in the truck.
- 2
We show up in the window we gave you. Our technician arrives in uniform, introduces himself, and walks the gate with you. We listen to the motor, check the arm or track movement, and test the control board, sensors, and remotes.
- 3
We hand you the written diagnosis and the written price. Before we open a panel, you know what’s broken, what we’re replacing, and what it will cost. OEM or quality aftermarket options are both priced out so you decide.
- 4
We do the repair. For a Linear slide gate, that often means re-setting limits and replacing a relay; for a swing arm, a new capacitor or actuator. We carry common Linear parts, which is why most repairs finish in one visit.
- 5
We test the full cycle. Open, close, obstruction reverse, remote range, keypad entry if you have one, and safety edge activation. The gate gets cycled at least ten times before we call it done.
- 6
You get the Kingswell Guarantee in writing. Every repair invoice carries a 365-day written guarantee. If the same repair fails inside that period, we come back and fix it at no charge.
What Linear Electric Gate Repair Costs in San Jose
The honest range depends on what failed. Here’s what we typically quote in San Jose for common Linear jobs, parts and labor together:
| Repair | Typical Price Range |
|---|---|
| Limit switch re-setting and adjustment (slide gates) | $165 – $245 |
| Start capacitor replacement (swing arm) | $185 – $280 |
| Control board relay replacement | $220 – $340 |
| Safety edge or photo eye replacement | $180 – $310 |
| Full control board replacement (APeX or MegaCode) | $380 – $620 |
| Complete swing-arm actuator swap | $650 – $1,050 |
What moves the price is access to the operator housing, whether the gate is swing or slide, and whether we’re using Linear OEM parts or a quality aftermarket equivalent. You’ll see the line items before we turn a single bolt, and the price we quote is the price you pay. Call (669) 800-5686 for a free estimate on your specific setup.

AfterWhy San Jose Homeowners Call Portcullis Gate Repair San Jose for Linear Work
Most of our Linear repair calls in San Jose come from people who have already tried another gate company and are done with the runaround. We’ve been a Kingswell company since 2008, and every Portcullis location is independently owned and operated but held to the same four Kingswell Guarantee promises: a written price before work starts, a real arrival window, a clean job site, and a written guarantee on the repair. Our techs are background-checked and uniformed, and they know Linear equipment because they also service LiftMaster, Mighty Mule, Ghost Controls, and DoorKing on a regular basis. If your Linear system turns out to have a deeper issue from a different brand component, we don’t have to guess, and we don’t have to sub it out. Dean Prescott signs off on the repair standard, and the 365-Day Done Right Promise means if it fails inside a year, the return visit is free. We don’t ask you to trust us; we hand you the written guarantee and the phone number of a live person who answers around the clock.
Frequently Asked Questions About Linear Electric Gate Repair in San Jose
In most San Jose cases, yes. Because we stock common Linear parts on the truck, the majority of slide-gate limit issues, swing-arm capacitor failures, and sensor problems are fixed in one visit. If your particular model needs a board we don’t carry, we’ll order it and give you a real arrival window for the follow-up, not an open-ended “sometime next week.” Call (669) 800-5686 and we’ll tell you honestly what the timeline looks like for your specific failure.
Independent repair generally does not void a Linear manufacturer’s warranty, and we’re careful to use OEM or OEM-equivalent parts that maintain the original spec. We never modify a control board in a way that a Linear warranty inspector could flag. If your system is still under warranty, we’ll tell you before we start whether a manufacturer claim makes more sense than paying out of pocket. As an independent Linear service provider, we’ll be straight with you either way.
If the operator is under 12 years old and the failure is a relay, capacitor, limit switch, or sensor, repair is almost always the better money. We’ll tell you when replacement is the honest call, which usually happens when the motor itself is seized or the board has multiple failed components. In that case, we can price out a new Linear unit or a comparable LiftMaster or DoorKing option, installed, with the same written guarantee.
In San Jose, this is most often a moisture-compromised safety edge or a misaligned photo eye, especially after the winter rains. The control board reads the false signal as an obstruction and reverses the gate for safety, which is exactly what it’s designed to do. We test each sensor circuit individually to find the false trigger before replacing anything, so you’re not paying for a new board when the real problem is a $40 edge sensor.
We do. Remote range problems, keypads that won’t hold a code, and MegaCode receiver issues are all part of our regular Linear service in San Jose. We’ll test your remote with a signal meter, re-program the receiver if needed, and show you that the gate works from the distance you actually use it. You get the same 365-day written guarantee on the remote repair as on any other component.
