Linear Gate Motor Replacement Nationwide

Linear Gate Motor Replacement: The San Diego Owner’s Guide

We replace Linear gate motors throughout San Diego, and most residential swing-gate actuator swaps run $850 to $1,600 installed, parts and labor included in writing before we start. A slide-gate motor replacement on a Linear SL or SLR series typically lands between $1,200 and $2,200 depending on the chassis and the condition of your drive chain or rack. If you call before noon, we can usually have a technician out the same day to confirm the diagnosis and give you a firm number.

Most people discover the motor is gone the same way: the gate stopped mid-swing one morning, then hummed on the next try, and now it’s completely silent with the keypad still lighting up. The control board has power, the remote is fine, but the motor itself won’t turn. In Linear units we see a lot of, the failure is usually the run capacitor, the gear train, or a burned winding in the motor itself, especially after a stretch of salty air and hard starts near the coast from Imperial Beach up through La Jolla.

Which Linear Models This Applies To

We carry and install replacements for the Linear actuator and motor lines most common on San Diego driveways: the LRA series (LRA10, LRA15, LRA20 swing-gate arms), the SL and SLR slide-gate operators, and the APeX and MegaCode series that show up on a lot of newer installs. If your unit has a blue or black housing with the Linear nameplate riveted on, there’s a good chance we have the part on the truck or can have it in hand within one business day.

Here’s the compatibility gotcha that catches owners out: the physical motor inside a Linear operator is not one universal part. A swing-gate LRA actuator motor is a DC gearmotor built into the arm itself, while an SL slide-gate operator uses an AC motor bolted to a separate gearbox and drive sprocket. They don’t swap. The right identification is the model number on the side label plus the voltage reading from the control board, and we check both before quoting anything. For OEM versus aftermarket, Linear’s own replacement motors carry the brand markup and sometimes a lead time; quality aftermarket equivalents with the same frame size, RPM rating, and torque output are available for most LRA and SL models, and we’ll tell you which one we recommend and why before you pay a dollar for either.

Signs Your Linear Gate Motor Replacement Is Failing

• The gate hums but doesn’t move. Power is reaching the motor but the starting capacitor has failed, so the motor can’t kick over. This is the most common early failure on Linear swing actuators in San Diego’s coastal humidity and often the cheapest fix if caught before the windings cook.
• The gate starts, then stops six inches later. The motor’s internal thermal overload is tripping. A gear train binding under load, a failing bearing, or low voltage from a tired transformer will all do this. Running it this way for weeks is how the motor gets too hot and dies permanently.
• The gate moves slower than it did last year. Brushes wearing down in a DC gearmotor or a sluggish capacitor will drag the speed down gradually. By the time it’s obviously slow, the motor is well past needing help.
• It only works in one direction, or responds to the remote intermittently. On older APeX boards this can be a relay, but when the motor itself is dying, the arm will often stall hardest in one direction first because the limit switch timing and gear wear concentrate the load there.
• A burned smell near the operator, or the housing feels hot to the touch after a cycle. That’s insulation breaking down inside the windings. Shut the breaker off and stop using the opener. A motor that’s running hot is a fire risk and past the point of adjustment.

Replacement Cost & What’s Included

For San Diego residential work, plan on these installed ranges:

• Linear LRA series swing-gate actuator replacement: $850 – $1,600 installed
• Linear SL / SLR slide-gate motor and gearbox replacement: $1,200 – $2,200 installed
• Motor-only replacement on a healthy Linear chassis: $450 – $800 installed, when the existing gearbox and drive are reusable

The spread comes down to three things: whether we’re swapping the whole actuator or just the motor inside it, whether your existing rack, chain, and mounting hardware are still straight, and whether the new unit needs fresh limit switches or wiring to match an older control board. Our written price includes the part, the labor, the wiring, and the re-tuning of your open and close limits so the gate cycles correctly. We walk you through the quote line by line before work starts, and the whole replacement is covered under our 365-Day Done Right Promise. If it fails inside a year, we come back and fix it at no charge.

DIY or Call Us?

You can safely check three things yourself: confirm the breaker is on, confirm the keypad and remote still trigger the control board, and listen for a hum or click from the operator when you press the button. Beyond that, we recommend you stop. A gate motor replacement on a Linear swing arm means working with a loaded spring or a gate leaf under tension, and a slide-gate motor involves line-voltage wiring and drive chain pressure. One wrong move with the gate unbolted and the arm can swing hard enough to do real damage. That’s not us protecting our trade, that’s just the truth about a 400-pound gate leaf and stored energy.

If the checks above show power but no motion, call (619) 793-3558 and describe what you hear. We’ll give you a real price range over the phone, send a background-checked, uniformed technician to your San Diego property, and put the final number in writing before anyone turns a wrench.
