We repair Linear gate openers across San Diego, and we do it as an independent Linear service provider – which means we tell you the truth about parts, pricing, and whether a repair actually makes sense before you spend a dollar. Most Linear opener repairs are completed in a single visit, and you’ll get a written price before any work starts. If you own a Linear and the gate won’t budge, call Calder Gate Repair San Diego at (619) 541-7844 – a live person answers, day or night.

This page is for San Diego homeowners who own a Linear gate opener and want straight answers: what typically fails, what it costs to fix here, and how fast we can get to you. We’re factory-familiar with Linear’s residential swing and slide gate lines, and we see plenty of them from Chula Vista up to Carlsbad. You’ll get the same treatment on a $200 limit switch fix as you would on a full control board replacement.
How Linear Products Fail – and How We Fix Them
- Linear LRA and LSO series – blown motor capacitor. The LRA (swing arm) and LSO (slide) openers run on a capacitor-start motor. When that capacitor goes, the gate hums but doesn’t move. In San Diego’s coastal humidity and inland heat swings, we see these fail faster than the national average. Our fix is a replacement capacitor rated for the original spec, not a generic one from the truck stock bin.
- Linear APeX series – limit switch drift. The APeX line’s limit switches (the small sensors that tell the gate where to stop) lose calibration after seasons of thermal expansion and contraction. The gate overshoots, slams, or stops short. We re-set and reseat the limits under load, not just at idle, which is where most quick fixes fall apart.
- Linear MegaCode receivers – signal loss after storms. Linear’s MegaCode receiver is generally solid, but San Diego’s marine layer and occasional heavy rain get into worn antenna seals. You press the remote, nothing happens, or range drops to ten feet. We replace the antenna assembly and reseal the housing, then test range from the street. If you’re still on an old single-button remote, we’ll talk you through options.
- Linear control board failures – power surge damage. Linear boards handle a lot, but SDG&E surge events and lightning strikes east of the 15 are a real thing. Symptoms: opener dead, no LED, nothing clicks. We diagnose board vs. transformer on site and tell you honestly if a replacement board at $300 – $500 makes sense versus buying a new opener for a bit more. We never push a board replacement without showing you the test results.
- Linear M series and older Pro series – gearbox wear. On slide gates especially, the steel-on-brass worm gear wears until the gate jerks or stops mid-travel. The gate might work when cold and stick when hot. We open the gearbox, show you the worn gear, and quote the OEM replacement part alongside a quality aftermarket option if one genuinely matches spec. No hidden upsell – you pick.
Styles & brands we work with





Our Linear Gate Opener Repair Process
- 1
You call, a human answers. Not a voicemail, not a bot. We get your address, your Linear model (if you know it), and what the gate is doing – or not doing.
- 2
We show up when we say we will. You get a live, trackable arrival time. Our technician arrives in uniform, background-checked, and ready with Linear-specific diagnostic gear.
- 3
We diagnose before we touch anything. Power test, motor test, limit switch check, receiver check, gearbox inspection. We show you the failed part on our meter or with a photo, because Nico Alvarez built this company on one idea: “Show you the part, write you the price, fix it right the first time.”
- 4
You see the price in writing. Before any repair begins, you get a written quote for parts and labor. The number on the invoice matches the number you approved. No surprises, ever.
- 5
We repair, test under load, and clean up. The gate cycles multiple times with weight on it, the limits are re-verified, and the safety edges are tested. We don’t leave until the gate operates correctly and the work area is clean.
- 6
You get the 365-Day Done Right Promise in writing. Every Linear repair carries a written guarantee. If the repair fails within 365 days, we come back and fix it at no charge. That’s the guarantee, by name, on every single job.

FAQs
If your Linear opener is still under the original manufacturer warranty, we work in a warranty-safe way: we use OEM Linear parts when you request them and we don’t modify the unit beyond standard repair practice. But realistically, most Linear openers we see in San Diego are past the warranty window. If you’re still covered, we’ll walk through your options honestly before any repair begins.
Most Linear repairs are done in one visit, typically 1 – 2 hours on site. If the opener needs a special-order OEM part, that’s usually 3 – 5 business days to source and install. We’ll tell you which scenario applies before we even schedule the first visit. For a current ETA on a specific Linear part, call (619) 541-7844.
If the repair is under $500 and the opener is under 10 years old, repair usually makes financial sense. If you’re looking at a control board, gearbox, and motor all in the same season, or if the opener is 15+ years old, replacement starts to win. We’ll show you both numbers and let you choose. We don’t make a commission on selling new openers – we make our reputation on giving you a straight answer.
No, not for the common items. Capacitors, limit switches, remotes, and receivers are typically stocked locally or available within a day or two. The longer lead times are for legacy Linear Pro series control boards and specific gearbox internals. We source OEM Linear parts through our regular supply chain, and we keep the most common repair items in the truck.
Yes. We handle Linear’s commercial and heavy-duty slide gate operators, which are common on mid-sized commercial properties around San Diego. For those, we do a full load test after the repair, because a commercial gate with a bad limit switch is a liability, not just an inconvenience. Call (619) 541-7844 and we’ll schedule a technician who’s actually trained on Linear commercial gear.
