Linear Gate Motor Replacement Nationwide

Linear Gate Motor Replacement: The Tarzana Owner’s Guide

A Linear gate motor replacement in Tarzana typically runs between $850 and $1,450 installed, depending on the model series and whether the arm bracket and mounting plate are still intact. We stock Linear-compatible motors and parts on our trucks, so most replacements are done the same day we diagnose the failure. The job includes removing the old motor, mounting the new one, setting limit switches, reconnecting the safety devices, and testing full travel before we hand you the photo log.

Most Tarzana homeowners call us because the gate stopped mid-travel, makes a grinding noise but won’t move, or hums without opening. The motor is usually still drawing power, but the internal gear train or capacitor has given out. On Linear swing-arm operators specifically, the arm bracket tends to fail before the motor itself, so we always check that connection point before replacing anything. If the bracket is cracked, replacing only the motor is a waste of money, and we’ll tell you that plainly.

We’re an independent gate repair company, not affiliated with Linear. That means we’re free to tell you when a repair makes more sense than a replacement, and we carry aftermarket equivalents we’ve tested alongside OEM Linear parts so you have a real choice on price.

Which Linear Models This Applies To

Linear gate operators fall into a few distinct series, and the motor replacement path is different for each. The most common in Tarzana driveways are the Linear LRA swing-arm series (LRA24, LRA34, and the older LRA1K), the sliding gate SL series, and the heavy-duty APeX series. If you open the control box cover, the model is printed on the circuit board or on a label inside the lid. We use that model number, plus a measurement of the motor shaft and the arm geometry, to match the correct replacement.

OEM Linear motors for the LRA24 run around $350 to $500 for the part alone, before labor. A quality aftermarket equivalent with matching amperage draw and travel specs lands between $200 and $320. The difference is warranty length and how tightly the limit-switch cams hold calibration. We’ve installed both, and our written quote lists which option we’re pricing so you decide before any work starts. One compatibility gotcha worth knowing: the LRA34 uses a different arm coupling than the LRA24, and they don’t interchange, even though the motors look nearly identical from the outside. We see this mismatch attempted more often than we’d like.

We also service and stock parts for LiftMaster, Mighty Mule, and Ghost Controls gates, so if your Linear turns out to be the wrong fit after inspection, we won’t leave you stranded waiting on a backorder.

Signs Your Linear Gate Motor Replacement Is Failing

• The gate hums but won’t move. The start capacitor has lost its charge or the armature is seized. In a Linear LRA, this usually means the internal gear reduction has worn to the point of binding, and the motor is fighting itself.
• The gate slows noticeably on hot afternoons. Tarzana summers routinely hit 100 degrees, and thermal expansion in the motor housing plus a tired capacitor makes the motor work harder. If it gets worse in heat months, the motor is on its way out, not the limit switches.
• The gate stops mid-travel and reverses for no apparent reason. A failing motor draws more amps, which trips the obstruction sensing in the control board. The board is fine; it’s reading a real load spike from a motor that’s laboring.
• You hear a grinding or knocking at the end of travel. The limit switch cams inside the motor housing have slipped. Left unchecked, the motor over-travels and strips the internal gears, which turns a $40 adjustment into a full motor replacement.
• The arm bracket looks cracked or the arm itself is bent. On Linear swing arms, a bent arm loads the motor off-axis, which eats the output shaft bearings and kills the motor from the outside in. Replacing the motor without straightening the arm means you’ll replace it again in eighteen months.

Replacement Cost & What’s Included

Installed Linear gate motor replacement in Tarzana lands between $850 and $1,450. The spread comes down to three things: which Linear series you have, whether we use OEM or a tested aftermarket motor, and whether the arm bracket, arm, and mounting plate are reused or replaced. A straightforward LRA24 motor swap with no bracket damage typically hits the lower end. An APeX series replacement with bracket fabrication, new arm, and control board recalibration sits at the higher end.

Every quote is written and handed to you before we touch a tool. That’s Haven Standard Clause 1, and it means the number we quote is the number you pay. The price includes the motor, all mounting hardware, limit switch set, safety device reconnection (photo-eyes, safety edges, and keypad interlock), full travel testing, and the documented photo record of what we found, what we set, and what we installed. Our 365-Day Done Right Promise covers the work: if it’s not right within a year, we make it right at no additional charge. Name what you found, name what it costs, name what you left behind.

The replacement itself takes 60 to 90 minutes on most Linear swing-arm models. Sliding gate motors run closer to two hours because of the drive chain and rail alignment. We’re not promising a same-day dispatch on new gate installations, but a motor replacement is a repair job, and we run those same day across Tarzana, including the neighborhoods along Reseda Boulevard and up toward the Ventura Boulevard corridor.

DIY or Call Us?

There are things an owner can safely check before calling: whether the breaker is on, whether the control box has power (a green LED on the board means yes), and whether anything is physically blocking the gate track or swing path. Those checks take five minutes and cost you nothing.

The motor itself is a different story. A Linear gate operator runs on 120V or 240V, and the capacitor inside the motor housing stores charge even after the breaker is off. If you don’t know how to discharge it safely, don’t open the housing. We’ve seen too many Tarzana homeowners buy a replacement motor online, get halfway through the swap, and discover the arm won’t seat or the limit cams won’t calibrate because the part was the wrong series. At that point the gate is dead, the old motor is half-disassembled, and the job is twice as expensive as it would have been had we done it from the start. If you’ve already bought a motor and want it installed, we’ll do that too, but call us before you open anything: (424) 258-8818. We’ll tell you over the phone whether the part you have will work with your Linear model.
