Linear Gate Motor Replacement Nationwide | Gatewood Fence & Gate

Linear Gate Motor Replacement: The Tarzana Owner’s Guide

We stock and install Linear-compatible gate motor replacements throughout Tarzana, and most swaps run between $650 and $1,400 installed depending on the model and what wore out around it. If your gate groans, stalls mid-travel, or trips the breaker when the arm tries to move, you’re likely looking at a failed motor or a failed capacitor dragging the motor down with it. Hal Gatewood keeps the common Linear parts on the truck, so most Tarzana calls are diagnosed and fixed in one visit.

Here’s the pattern we see in Tarzana week after week: the gate worked fine for years, then one morning it moved slow, then slower, then stopped and hummed. The control board still clicks. The keypad still beeps. The motor is what died. By the time most people call, they’ve already tried the remote twice and given the gate a shove with their shoulder. We’ll skip all that and tell you what you actually need.

Which Linear Models This Applies To

Linear built gate operators under a few different lines over the years, and the motor isn’t interchangeable across all of them. The two series we work on most in Tarzana are the residential LD (Linear Drive) line and the heavier LDO commercial units. The LD 033 and LD 050 pull duty on most driveway swing gates in the valley, while the APeX and older L-Series show up on a fair number of mid-century Tarzana properties where the original builder spec’d Linear.

Here’s the compatibility gotcha that saves people time and money: Linear used different motor winding specs between the 1/3 hp and 1/2 hp versions, and the mounting bolt pattern changed between production runs. You can’t always drop a new motor into an old LD 033 chassis without an adapter plate, and some of the older L-Series units need the control board replaced at the same time because the motor current draw spec changed. The OEM label on the motor housing will show a part number that starts with “LM” followed by a series code. Take a photo of that label before you do anything else. If it’s gone, the model plate on the operator chassis gets us to the right part eight times out of ten.

On the OEM versus aftermarket question: Linear’s own replacement motors are built to the original torque curve and tend to run cooler in the Southern California heat. Quality aftermarket motors exist, but for Linear specifically, we’ve seen too many generic motors draw high on startup and trip the thermal overload in July. In Tarzana, where a west-facing gate bakes from about 2 p.m. onward, that matters. We’ll quote you both options and tell you which one we’d put on our own gate.

Signs Your Linear Gate Motor Replacement Is Failing

• Sluggish start, especially when cold. The start capacitor is on its way out or the motor windings are losing insulation resistance. In Tarzana’s dry heat, capacitors age faster than the motor itself, and a $30 capacitor left too long becomes a $400 motor job.
• Humming with no movement. Power reaches the motor but the armature shaft won’t turn. On Linear units this is often the gear reduction binding, but it can also be a seized bearing. Either way, continuing to press the button cooks the windings.
• Intermittent stops mid-cycle. The motor’s thermal overload is tripping. That’s the motor telling you it’s overheating. It’ll work again in ten minutes, which fools people into waiting. It gets worse every week until it stops altogether.
• Burnt electrical smell near the operator housing. Insulation is breaking down inside the motor casing. That smell never fixes itself. It means the motor is done and possibly the control board’s relay contacts along with it.
• Gate drifts or pushes open easily by hand. The motor’s internal brake or the operator’s limit switch isn’t holding. With Linear swing operators, a soft brake lets the gate drift into the curb or a parked car. That’s a safety issue more than a convenience one.

Replacement Cost & What’s Included

For a standard residential Linear gate motor replacement in Tarzana, you’re looking at $650 to $1,100 installed. That includes the motor, the start capacitor, fresh wiring connectors, limit switch adjustment, and testing through at least fifteen full cycles. If the gear reduction box shows wear from a heavy gate, or the control board needs to be replaced to match motor current specs, the upper end of the range comes into play, roughly $1,100 to $1,400.

Here’s the line-item reality so nothing is a surprise:

• Linear OEM motor: $380 to $620 depending on series
• Capacitor and connector kit: $40 to $75
• Labor (same-visit install, test, adjust): $230 to $450
• Gear reduction or control board work (if needed): $250 to $425

We write the price down before we touch a screw. You sign it, we do the work, and the invoice matches. The replacement carries our 90-Day Done Right Promise: if it isn’t right, Hal comes back and makes it right. No fine print, no “up to” language. We also stock LiftMaster, Mighty Mule, and Ghost Controls parts, so if it turns out the Linear label is one of three motors on your property, we handle that too.

DIY or Call Us?

Truthful answer: swapping a gate motor is not a plumbing washers job, and it can hurt you. These operators sit inside a metal housing wired to line voltage, and a gate under tension stores energy you don’t see until it releases into your hand. We’ve had to undo enough homeowner work in Tarzana to say this plainly: if you’re not confident working around live electrical and a gate that can pinch or crush, call someone who is. That’s not a sales line. It’s what Hal tells his own neighbors.

What you can safely do: photograph the motor label, check that the breaker hasn’t tripped, and listen for whether the unit hums or stays silent. That information shortens our diagnosis. What goes wrong with DIY on Linear units specifically: the limit switches are set with the motor in a test mode, and if you reassemble the arm and power it up without setting the limits, the gate can rip a hinge or drive the arm through a stucco column. We’ve fixed that exact mess on a Tarzana driveway twice in the last year.

Call us at (818) 514-7606 and we’ll sort out whether you need us for fifteen minutes or a full replacement. The estimate is free, and there’s no trip charge inside the county.
