Linear electric gate repair in San Francisco typically costs between $185 and $520 depending on what failed, and most jobs we see are completed the same day we arrive. We’re an independent Linear service provider, not a factory warranty center, which means we can usually get your gate moving again without the two-week wait for an authorized dealer to free up a slot. The price you hear first is the price you pay: a written quote before we touch anything, with no dispatch fee surprise and no upsell when we’re already on site.

If you own a Linear gate opener in San Francisco and it’s humming without moving, clicking without responding, or dead silent after the last fog bank rolled through, this page is for you. Call (628) 227-2771 and a live person answers around the clock. We’ll ask what you’re hearing and seeing, then tell you honestly whether it sounds like a $40 part or a deeper board problem before anyone rolls a truck.
Key takeaways:
- We repair Linear gate motors, openers, keypads, remotes, safety sensors, and control boards.
- Written line-item pricing before any work starts, every visit.
- Same-day service in most San Francisco neighborhoods when you call before early afternoon.
- 365-Day Done Right Promise: if it isn’t right, we make it right.
How Linear Products Fail – and How We Fix Them
Linear has been building residential gate operators for decades, and a few failure patterns show up over and over in San Francisco. The marine air is part of it, but so is the way Linear designs certain components. Here’s what we actually find when we open the cover:
- Linear LSO and LS series swing gate operators: limit switch drift. These older workhorse units relied on mechanical limit switches that collect fog-driven moisture in San Francisco’s western neighborhoods. When the switch corrodes, the gate stops mid-travel or slams harder than it should. We replace the switch, reset the travel limits, and test the gate through ten full cycles before we call it done.
- Linear APeX series: control board capacitor failure. The APeX line put the controller board in a sealed housing, which helps with moisture but traps heat. After a few years of San Francisco temperature swings, the electrolytic capacitors dry out and the board stops sending power to the motor. We test the board on the spot rather than guessing, then install either an OEM replacement or a quality aftermarket board if your budget matters more than brand-matching.
- Linear MegaCode receivers: rolling code desynchronization. If your remote stopped working after a power flicker or a neighbor’s new gate system went in nearby, the receiver may have lost its rolling code sync. This is a reprogramming job in most cases, not a hardware failure, and it takes about twenty minutes. We’ll also check whether the receiver antenna has been damaged, which is common on gates that live close to the street.
- Linear keypads and transmitters: button pad wear and moisture ingress. The rubber membrane keypads on Linear exterior stations crack after a few years of direct sun on the east side of the city, and once moisture gets behind the membrane, the keypad starts ghost-pressing or refusing digits. We replace the pad or the whole station, and we always recommend the weather-sealed variant for hillside installations that take the brunt of the wind.
- Linear safety photo eyes: fog and spider webs triggering false obstruction faults. In the Richmond and Sunset districts especially, the combination of fog condensation and spider silk across the lens makes the gate reverse constantly for no apparent reason. We clean, realign, and test the eyes, then advise if the lens itself has micro-crazed from salt air and needs replacing. A fogged photo eye is the single most misdiagnosed Linear problem we see, because the symptom looks like a motor issue.
One thing we’ve learned from years of servicing Linear gates in San Francisco: the gate that gets ignored for four winters in a row has a lot of feelings to work through. The motor may still be fine. The wiring may be fine. But something always gives, and it’s usually the cheapest component that took the whole system down.
Styles & brands we work with





Our Linear Electric Gate Repair Process
Most repair calls follow the same calm sequence, and you’ll know what’s happening at every step:
- 1
You call (628) 227-2771. A live person answers and asks what the gate is doing (or not doing). We’ll give you a realistic service window and a rough idea of what we suspect, based on the symptoms.
- 2
We arrive and diagnose. The technician opens the operator housing, tests incoming voltage, checks the board, the motor, the wiring, and the safety circuit before announcing anything. You get told what we found in plain English, not part numbers.
- 3
You get a written price. Before we replace a single screw, you’ll see the exact line-item cost. We’ll tell you what’s optional, what’s recommended, and what can wait. No pressure, no “while we’re here” surprises.
- 4
We repair with the right parts. For warranty-sensitive units, we use OEM Linear parts. For older units where the OEM board costs more than a quality aftermarket equivalent and the warranty has long expired, we’ll give you both options and let you choose.
- 5
We test the full system. Ten open-close cycles minimum, including safety edge response and photo eye interruption. We want the gate to fail here while we’re standing next to it, not after we leave.
- 6
We clean up and show you. Shoe covers and drop cloths stay in place until the job is done. Before we leave, we walk you through what was replaced and why, and we send you a photo of the clean work area. The 365-Day Done Right Promise means if anything we touched acts up within the year, we come back and fix it.

Why San Francisco Homeowners Call Latch and Post Gate Repair San Francisco for Linear Work
Cody Beckman and our crew have been working on Bay Area gates since 2009, and Linear is one of the brands we know from the inside out. Every gate comes down to two parts, the latch that holds it and the post that carries it. That’s the job we focus on, and it means we don’t get distracted by gutter cleaning or appliance repair. Just gates, all day, every day, including the quiet residential streets feeding into Noe Valley where older sliding gates wear their tracks down until one afternoon the gate won’t budge.
We stock common Linear parts on the truck, which means fewer wasted visits. When your Linear opener shares a property with a LiftMaster, Mighty Mule, Ghost Controls, or DoorKing operator, we service those too. Our techs are background-checked and uniformed, and we run every visit on the Cedarwell C.A.R.E. values: clean up like it’s our own home, ask before we move or touch anything, respect your time and quiet hours, and explain the price before the work. Shoe covers on every visit. Drop cloths down before we step inside. A cleanup photo before we leave.
A gate that opens quietly and closes all the way is one of those things you stop noticing, and that’s exactly the point.
FAQs
Yes, most Linear repairs are completed the same day we arrive, and we answer calls around the clock at (628) 227-2771 so we can get a technician scheduled quickly. The exception is when a specific OEM Linear part isn’t on the truck, in which case we’ll tell you the part lead time before you spend a dollar.
No, we’re an independent Linear service provider, and using a third-party repair company does not void a Linear manufacturer warranty under the Magnuson-Moss Warranty Act. If your unit is still under warranty, we’ll use OEM Linear parts and follow factory torque and calibration specs so the warranty stays intact.
A Linear control board replacement in San Francisco typically runs between $280 and $520 depending on the model and whether you choose OEM or quality aftermarket. We’ll quote the exact number in writing before we order or install anything, and estimates are free.
If your Linear operator is under ten years old and the motor is still strong, repair is almost always the better value. We’ll tell you honestly if a repair would cost more than half the price of a new operator, and we’ll never recommend a replacement just because it’s easier for us. The decision comes down to the numbers you see in writing, not a sales pitch.
Yes, safety sensor repair and alignment is one of the most common Linear jobs we do in San Francisco, where fog and salt air cause constant false obstructions. We test the full safety circuit, including the photo eyes and the reversing edge, as part of every repair. Call (628) 227-2771 and we’ll walk through what your gate is doing before you spend anything.
