Linear Gate Motor Replacement Nationwide

Linear Gate Motor Replacement: The Tarzana Owner’s Guide

We stock and install Linear-compatible gate motor replacements across Tarzana, with most installed jobs running between $650 and $1,150 depending on your model and what failed. If you have a Linear opener that has quit or is grinding, we can usually match the motor on the first visit and have it turning again the same day. What most Tarzana owners notice first is the gate moving slower than it used to, then one morning the operator hums but the gate doesn’t move at all.

Linear has been a workhorse in Southern California driveways for years, and in this part of the San Fernando Valley we see plenty of them still in service on homes along Reseda Boulevard, in the hills above Ventura Boulevard, and throughout the neighborhoods east of Corbin. The motors are generally solid. What tends to go first in Tarzana’s heat and dust is the capacitor or the limit-switch assembly, not the windings themselves.

Key Takeaways:

• Typical installed Linear motor replacement in Tarzana: $650 to $1,150, quoted and agreed before we start.
• We carry Linear-compatible OEM and quality aftermarket motors on the truck.
• Most swaps are done the same day, in a single visit.
• Ironworks Gate Co. is an independent gate service company, not affiliated with Linear.
• Every replacement carries our written 90-Day Done Right Promise.

Which Linear Models This Applies To

Linear has produced several lines over the years, and the motor that is right for your gate depends on which series you have. The most common we replace in Tarzana are pulled from the Linear LDO and TS series swing operators, the SL, SLR, and SLD slide operators, and the ACT20/ACT30 and APeX series used on larger estate gates. Each line uses different motor voltages and gearbox mounts, so matching by model number and serial plate is the only honest way to quote a job.

Here is the compatibility gotcha that catches a lot of owners: a Linear motor from an older SL series slide operator will not drop into a newer SLR housing without changing the drive coupling and sometimes the capacitor value. The mounting bolt pattern looks close, but it is off by a few millimeters, and forcing it ruins the gearbox seals. The fix is not difficult if you know it beforehand. Our techs check the nameplate rating and shaft dimensions before recommending anything, because guessing costs you time and money.

On the OEM versus aftermarket question for Linear specifically: the OEM motor is made to the factory torque curve, and for gate applications that matters because the load changes as the gate swings or slides. A quality aftermarket replacement from US Automatic or an equivalent winding house works fine on most LDO and TS units and runs about 25 to 30 percent less. We stock both on the truck and we will tell you straight which one makes sense for your gate’s age and how long you want it to last. For a 15-year-old operator in Tarzana’s sun, the aftermarket motor is often the more sensible choice.

Signs Your Linear Gate Motor Replacement Is Failing

• The gate starts fine but stalls midway. The motor windings lose torque as they heat up. This is the classic early warning on Linear swing operators here in Tarzana, where direct sun on the operator housing pushes internal temperatures high, especially in July and August.
• A loud hum with no movement. Usually the capacitor has failed. The motor is getting voltage but no starting kick. A capacitor on a Linear unit is a ten-minute fix if you catch it before the motor overheats fighting the load.
• The gate moves slower than it did six months ago. Worn brushes in the DC motors on Linear slide operators, or weakened magnets in older AC units. Once speed drops by around twenty percent, the motor is working harder than it should and failure follows quickly.
• A burning smell from the operator box. Insulation on the windings is breaking down from heat. By the time you smell it, the motor is done. Stop running the gate and call.
• The gate opens but will not close without help. We hear this regularly from owners in the Braemar area hills: the motor has lost enough torque that gravity is now beating it on the closing cycle. A healthy Linear motor should move the gate through both directions without strain.

Replacement Cost & What’s Included

In Tarzana, a Linear gate motor replacement with labor typically runs $650 to $1,150 installed. The lower end covers a straightforward swap on an LDO or TS swing operator with a quality aftermarket motor. The upper end covers OEM Linear motors on slide operators like the SL or SLD, where the job includes pulling the housing, replacing the coupling, and re-tensioning the drive chain. Every quote is firm before the first bolt comes out, and if we find something unexpected when we open the box, we stop and talk to you before doing anything.

Parts and labor are separated on the invoice so you know exactly what you are paying for. The motor itself carries its factory warranty, and our labor on every replacement is covered by the written 90-Day Done Right Promise. Here is the pricing breakdown by job type:

• LDO/TS swing motor replacement: $650 to $850 installed
• SL/SLR slide motor replacement: $750 to $980 installed
• ACT20/ACT30 or APeX series: $850 to $1,150 installed
• Capacitor replacement (if caught before motor damage): $120 to $180 installed

DIY or Call Us?

Here is the honest split. What you can safely check yourself: whether the breaker is on, whether the keypad and remote are actually sending a signal, and whether a branch or a rock is blocking the gate track. Those checks cost you nothing and we will ask about all three when you call. Beyond that, this is where DIY goes wrong. A Linear motor swap means opening the operator housing, releasing the drive chain or arm, and working with 120V or 24V line voltage, sometimes both in the same box. The capacitors hold charge after the power is cut. One wrong probe and you are getting a hard lesson in electricity, or you are bolting the motor in with the capacitor wired backwards and frying it the first time the board powers up.

We have had more than one Tarzana homeowner hand us a box of parts and a story about a video that made it look easy. By the time we sort it out, it costs more than the original job would have. If your Linear motor is failing, call us at (925) 263-6107 and we will give you an honest read on the phone before we even schedule the visit.
