Linear Gate Motor Replacement Nationwide

Linear Gate Motor Replacement: The Fort Worth Owner’s Guide

Replacing a failed Linear gate motor in Fort Worth typically costs between $650 and $1,200 installed, depending on the model, horsepower rating, and whether the arm or gearbox also needs attention. Most Linear swing-gate and slide-gate motor swaps are done in a single visit, and Calder Gate Repair Fort Worth keeps the most common Linear-compatible arms, boards, and complete motor assemblies on the truck so you’re not waiting on a parts shipment. Here’s how it usually goes: the gate starts moving slower than it used to, then it hesitates, then one morning it hums without moving or just sits there silent while you’re late for work. That’s the failure pattern we see most often in Fort Worth neighborhoods, and it’s almost always the motor assembly itself or the control board driving it, not some mystery gremlin.

We’re an independent gate repair specialist, not a Linear dealer, which matters because it means we’ll tell you when a full motor replacement is actually necessary versus when a $40 limit switch or a new capacitor would fix the same symptom. Nico Alvarez has been pulling apart Linear openers since trade school, and the first thing he’ll tell you is that Linear gearboxes are tougher than their boards. More on that below.

Which Linear Models This Applies To

Linear has been slapping their name on gate openers for decades, which means the “same” 1/2 HP motor shows up across a whole range of series badges: the LDO, the LDCO, the APeX, the PRO series, and the older LS models. If you can read the model plate on the side of the motor housing, we can usually confirm cross-compatibility in about ninety seconds on the phone. That plate is typically located near where the arm connects to the gate or on the underside of the operator cover.

The big gotcha with Linear: two different “Linear 1/2 HP” operators might use different arm styles, and the arm length depends on gate geometry, not just the motor. Tarrant County has a lot of wide driveway gates on acreage properties east and south of downtown, and those longer arms put more torque demand on the gearbox. A stock original-equipment (OEM) Linear replacement arm is the smart call when the metal itself is worn at the pivot. For the motor and capacitor side, a reputable aftermarket match rated for the same RPM and shaft dimensions will run quieter and save real money over the Linear-branded box. The shaft is 3/4 inch on the older LDO series and metric on APeX units, and no, they don’t interchange without an adapter plate you’ll wish you’d skipped.

Fort Worth summers are rough on electronics. Heat breaks down capacitors faster than people realize, and a Linear opener that’s been baking on a west-facing brick column since 2016 has likely cooked through its start capacitor at least once already. If your motor hums but won’t start, that’s the first thing we check, because it’s a $35 fix that feels like a full motor failure.

Signs Your Linear Gate Motor Replacement Is Failing

• Hum but no movement. The start capacitor is toast or the arm gear has stripped. This is the number one call we get in Fort Worth when temperatures spike, because capacitors fail progressively and the last heat wave finishes them off.
• Gate moves slower than it did six months ago. On Linear swing operators, that’s typically a failing run capacitor or a gearbox losing lubrication through a seal leak. Ignoring it means the motor works harder, runs hotter, and dies sooner.
• Intermittent stops mid-travel, then starts again on the next command. The limit switch assembly inside the Linear arm is wearing out. Those small mechanical switches, the ones that tell the gate where “open” and “closed” are, wear down and fail erratically before they fail completely.
• Remote range drops to almost nothing. This one tricks people into replacing remotes when the real issue is a failing receiver or a brown-out-damaged board inside the Linear operator itself.
• The gate was stuck open (or closed) and the motor was hot to the touch. Heat means the motor is pulling too many amps, usually fighting a bad capacitor, a misaligned gate, or a hinge problem. Replacing the motor without fixing the drag puts you right back here in a year.

Here’s Nico’s signature line for diagnostics: “Tell me what it’s doing, or not doing, and I’ll tell you exactly what it needs.” That’s not a sales pitch. It’s how he works. Most of the time the symptom tells us the failure point before we ever unbolt a cover.

Replacement Cost & What’s Included

Here’s the pricing picture for Linear gate motor replacement in Fort Worth. These are installed ranges, not parts-only, and they reflect what we’ve actually charged across jobs in Fairmount, Arlington Heights, Wedgwood, and out toward Summerfields:

• Start or run capacitor replacement: $145 to $225 installed, if that’s genuinely the failure.
• Limit switch replacement (arm opened up, switches swapped): $190 to $310 installed.
• Control board replacement (aftermarket or OEM Linear equivalent): $285 to $475 installed.
• Complete Linear swing-gate motor replacement, 1/3 to 1/2 HP: $650 to $950 installed, including arm adjustment and travel tuning.
• Complete Linear slide-gate motor replacement: $800 to $1,200 installed, varies by track condition and gate weight.

Every quote includes the removal of the old part, installation, wiring verification, limit and force adjustments, and our 365-Day Done Right Promise in writing. If the replacement fails inside a year, Calder Gate Repair Fort Worth returns free and makes it right, no invoice, no argument. And the price we quote is the price on the invoice. Always a written quote before we turn a bolt, and the number doesn’t change at the door. Gate openers wear out in stages, and the fixing should never be a mystery.

DIY or Call Us?

What’s worth checking yourself: the breaker didn’t trip. The remote battery isn’t dead. Nothing obvious is jamming the gate, like a fallen branch in the track. Those three checks take two minutes and genuinely solve a surprising number of no-start calls.

What’s not worth it: opening a Linear motor housing and probing the capacitor. Capacitors store a charge even with power disconnected, and the wrong move there is a real shock, not a tingle. Same goes for any work inside the control board compartment, because one crossed wire can fry a board that was fine before the mistake. If the motor hums without moving, if it’s hot, if it arcs when you tap the side, or if the gate moves under force from your hand when the operator says it shouldn’t, stop there. Call (682) 432-9830 and let one of our uniformed, background-checked technicians diagnose it. The diagnosis call costs less than the parts most owners buy by guessing wrong.
