How Linear Products Fail - and How We Fix Them
Linear operators are common on Northridge driveways, especially on homes built in the 1980s and 1990s when the LDO and APeX series were the go-to choices for sliding gates. They’re solid machines, but after fifteen or twenty years of San Fernando Valley sun and the occasional Northridge wind gust, certain failures show up more than others. These are the ones we see most:
- APeX series limit switch failure. The original Linear APeX units used mechanical limit switches that wear out, causing the gate to stop short of fully open, or slam hard into the end stop and bounce back. The fix is replacing the limit switch assembly and recalibrating travel. We keep OEM limit assemblies stocked on our trucks for the most common APeX models.
- LDO series capacitor failure in the starting circuit. On older Linear LDO swing and slide operators, a dead capacitor is often the reason the motor hums but doesn’t move. Homeowners sometimes assume the motor is burned out, but a $40 capacitor often brings it back to life. We test first, replace second.
- Gearbox wear on Linear slide operators. The worm gear in the gearbox on Linear SL and SlideGate models can develop play after years of use, causing the gate to shudder while moving or make a grinding noise on start. The repair is a new gearbox or gear set, not a full operator replacement.
- Control board failure after power surges. Northridge sits close enough to the hills that summer thunderstorm season and rolling brownouts produce power spikes that Linear control boards don’t always shrug off. We see blown relays and cooked transformer secondaries, especially on units without any surge protection on the circuit. Part of our repair includes adding surge suppression where it’s missing.
- Remote receiver range loss on Linear Multi-Code systems. Linear built a name in gate access with the Multi-Code remote line, and those older receivers lose sensitivity over time. If your remotes only work from ten feet away, the receiver’s antenna trim or a failing receiver module is usually the cause. We diagnose the receiver before we sell you new remotes.
Our Linear Gate Motor & Opener Process
Here’s how a Linear gate motor or opener job goes when you call Ironworks Gate Co.:
- 1
You call and a person answers. No voicemail tree. You describe what the gate is doing, and we ask the right questions to figure out if this is an emergency or a scheduled visit.
- 2
We arrive on time, prepared. Our trucks carry Linear-specific test gear and the common OEM parts for APeX, LDO, and SlideGate models, so most diagnosis and repair happens on the spot.
- 3
We diagnose before we touch anything. Voltage, amperage, limit state, gearbox wear, and receiver output all get checked. You hear the findings in plain English, not trade jargon.
- 4
We quote the repair in writing before any work starts. That price includes parts, labor, and the cleanup. If you say no, we pack up and leave with no charge beyond the service call.
- 5
We make the fix. The exact repair depends on the failure, but wherever possible we use OEM parts. Some Linear parts are discontinued, and in those cases we use quality aftermarket replacements that meet or exceed the original spec. We’ll tell you which is which before we install it.
- 6
We test the gate under load. Multiple open and close cycles, manual release check, safety reversal, and remote range verification. The job isn’t done until the gate opens when it should and stays put when it shouldn’t.
What Linear Gate Motor & Opener Costs in Northridge
Linear repair and replacement pricing in Northridge depends on the failure and the operator model. Here’s what we typically see:
- Capacitor replacement on LDO or APeX series: $285 to $385
- Limit switch replacement and recalibration: $310 to $440
- Control board replacement: $420 to $640
- Gearbox or gear set replacement: $440 to $590
- Full operator replacement (slide or swing, installed): $1,800 to $3,200 depending on gate weight and options
What moves the price? Gate length and weight, whether we’re repairing or replacing the operator, and whether existing wiring and photo eyes can be reused. We settle the quote before work starts, and no charge ever appears on the bill that wasn’t on the written estimate. Call (925) 966-4150 for an exact number on your gate.
Why Northridge Homeowners Call Ironworks Gate Co. for Linear Work
We’ve been serving Northridge and the San Fernando Valley for over 42 years, and we still answer our own phone. The technician at your gate is background-checked, in uniform, and has worked on enough Linear operators to know the difference between an APeX 3000 and an SL slide unit without looking at the label. When a Linear part is discontinued, we know which aftermarket supplier makes the right replacement and which ones don’t. We also service LiftMaster, Mighty Mule, Ghost Controls, and DoorKing, so if your property has more than one operator brand, one visit covers all of them.
If anything isn’t right after we leave, our 90-Day Done Right Promise covers it in writing. We come back and make it right. No paperwork, no arguing, no exceptions. Victor Salinas grew up here in Northridge, and he’s not going to run a company that hides from its own work.
FAQs
Linear’s gate operator line has changed ownership over the years, and many older models like the APeX and LDO series are discontinued. Parts availability varies by model, but we maintain stock of the most common Linear repair parts and source quality replacements for what’s no longer in production.
We repair far more Linear operators than we replace. The majority of failures, including capacitors, limit switches, gearboxes, and control boards, are repairable at a fraction of a complete operator. Replacement only comes up when the operator is beyond economical repair or the gate itself has outgrown it. Call (925) 966-4150 and we’ll tell you which camp yours falls into.
For a gate stuck open or stuck shut, we can usually dispatch same day in Northridge and the surrounding Valley, and most repairs are completed in one visit. Live phone support is available 24 hours a day, 7 days a week. A person answers the phone, not a machine.
As an independent Lincoln service provider, we’re not a manufacturer-authorized warranty station, so we can’t file warranty claims on your behalf. That said, if your operator is under warranty, we’ll tell you if the failure looks like a warranty item before you pay us a dime, and we’ll help you understand what the manufacturer needs for a claim.
If the operator is on a gate it’s been running for twenty years, the steel and the opener have grown old together. A repair under $500 usually makes sense. A board, gearbox, and limits all failing at once often means a new operator is the smarter money, and we’ll give you an honest recommendation with numbers to back it up.
Both. Linear operators run swing gates and slide gates all over Northridge, and our techs are trained on the full range, from the older LDO swing arms to the newer slide operators and Linear-compatible gate access systems.
