Linear Gate Motor Replacement: The University Park Owner’s Guide
We stock and install Linear-compatible gate motor replacements throughout University Park, with most swaps running $650 to $1,450 installed depending on your model and what we find when we open the housing. We keep the most common Linear swing and slide motor parts on the truck, so a lot of these are same-day jobs once we confirm the model. The way most University Park homeowners find out this part has failed is pretty simple: the gate stops moving, the opener hums without budging the leaf, or the gate drifts closed on its own after it’s been opened.
When a Linear gate motor gives out, it’s rarely a mystery. Five or six things account for nearly every failure we see, and most of them leave clues you can spot from the driveway before you ever call anybody. The good news is this is the kind of repair we do in the driveway, with the gate still hanging on its hinges, and we stand behind the parts and the labor with our 90-Day Done Right Promise.

Which Linear Models This Applies To
Linear has been making gate openers for a long time, and the model spread is wider than most people think. The three families we see most often in the University Park area are the older LS series (locking solenoid), the AM series (arm operator), and the SL series (slide operator). Each one uses a different motor assembly and a different mounting pattern, so the first thing we do is read the data plate on the housing or the underside of the motor itself. If the plate is faded or painted over, we measure bolt spacing and the output shaft diameter. There’s a compatibility gotcha with Linear: the older LS-series motors used a 1-inch output shaft with a single flat, while the later AM-series used a 3/4-inch shaft with a woodruff key. That’s a half-inch difference that’ll leave you with a motor that bolts up but can’t drive the arm. We’ve fixed that mistake for more than one University Park homeowner who bought a cheap “Linear replacement” online that didn’t match their machine.
On the parts side, you have two honest options. OEM Linear motors still exist for many models, though lead times have stretched in the last few years. A good aftermarket equivalent, built to the same mount pattern and duty cycle, often costs 30 to 40 percent less and holds up fine in our climate. We stock both on the truck for the most common models and we’ll show you the label on each so you know what you’re buying. Independent service provider, by the way: we are not affiliated with Linear, and we don’t pretend to be. We just fix their stuff.
Brands aside, we also keep parts on the shelf for LiftMaster, Mighty Mule, and Ghost Controls operators, which matters if you’ve got a mixed setup or a neighbor with a different machine. The truth is most gate motors in this part of Texas live hard: University Park heat baking the housing at 105 degrees in August, a cold snap in January, humidity in the spring. A motor that would last nine years in Ohio might give you five or six here, especially if the limit switches were never reset after the gate settled.
Signs Your Linear Gate Motor Replacement Is Failing
- The opener hums but the gate won’t move. That hum is the start capacitor or the motor trying to spin against a seized gear or a dead spot in the windings. In Linear swing operators, the plastic drive gear inside the arm assembly strips and the motor just spins free. The motor itself might still be fine, which is why we diagnose before we quote a replacement.
- The gate drifts closed after opening. On older Linear models, the mechanical brake inside the motor housing wears out, and the load of the gate slowly wins. If you can push the gate open and it creeps back toward the post, the brake is cooked. This is not something to let ride; a drifting gate is how fingers and bumpers get pinched.
- The gate stops halfway and the operator flashes a fault. Linear control boards throw a flash code when the motor draws too many amps, which usually means the motor windings are breaking down or the internal gears are binding. Replacing the board without checking the motor is the most common mistake we see from handymen out here, and it’s the fastest way to pay twice for one breakdown.
- The operator worked fine until the last storm. Water intrusion in the housing corrodes the motor’s internal contacts and shorts the windings. We see this on Linear units mounted low to the ground where June downpours in University Park splash up underneath. If the housing seal is compromised, any new motor you put in there is living on borrowed time until that seal is replaced too.
- The gate opens an inch, then stops. That’s almost always the current-sensing circuit in the control board reading an overcurrent from a motor that’s starting to fail. The motor bearings get gritty, the amp draw spikes, and the board shuts it down to protect itself. We test the motor independently before we ever recommend swapping the board.
Replacement Cost & What’s Included
For a Linear swing gate motor replacement in University Park, you’re generally looking at $650 to $1,050 installed including the part and the labor, assuming the arm assembly is still serviceable and we’re not fighting corroded fasteners. Slide gate motor replacements run higher, usually $950 to $1,450, because the motor assembly is bigger, heavier, and the chain and sprocket usually need to be checked or replaced at the same time. If the control board has been damaged by a failing motor, add $250 to $400 for the board replacement.
Every price I give you is laid out in writing before we start, and we don’t come back at the door with a different number. That’s not how we operate and it never has been. The replacement includes the motor, the mounting hardware we remove and replace, re-tensioning of the chain or arm if needed, re-setting the limit switches and force settings, and a full test cycle to make sure the gate closes clean, latches, and reverses on obstruction. We also throw in a free second opinion on any written estimate you bring us. And note: we offer $40 off any repair over $200 and a permanent 10% discount for seniors and veterans. You shouldn’t have to ask for those, but they’re there.
DIY or Call Us?
There are things you can safely check yourself, and then there’s the part where people get hurt. It’s true here like it is everywhere: gate motors run on household voltage, the capacitors inside hold a charge after the power is cut, and a gate leaf weighs several hundred pounds. If a spring or a chain lets go while you’re under that thing, the math is not in your favor. We say this plainly because we’ve been called out to jobs where a homeowner tried to save money and spent two hours in the ER instead.
What you can do: check the breaker, look for a tripped GFCI outlet near the operator, and wipe off the photo eyes. If the gate hums, drifts, or stops halfway, that’s a motor situation and we’d rather you call (936) 296-2568 before poking around inside the housing. We come out, we test the motor with a meter, and we tell you exactly what’s wrong with it. If it’s shot, we usually have the replacement on the truck. Hand me your number and I’ll call you back, same day, every time.
FAQs
Expect five to seven years from a Linear gate motor in our climate, versus eight to ten in cooler, drier regions. The heat and humidity in University Park accelerate wear on motor windings, capacitors, and internal plastic gears, and a gate that gets cycled eight to ten times a day will burn through a duty cycle faster than one that moves twice. If it’s a swing operator that hums loudly and the gate is visibly out of plumb, the motor is working against the gate every single day. We can quote you a replacement and set the gate right at the same time; call (936) 296-2568 for a free estimate.
Sometimes, yes. If the start capacitor has failed, the brake is worn, or the internal plastic drive gear is stripped, we can often rebuild the motor assembly without replacing the whole thing. If the motor windings themselves are burned or shorted, replacement is the only honest fix, and we’ll never rebuild something that’s going to limp along for six months and fail again. The price we quote for a rebuild is the price you pay, and the 90-Day Done Right Promise covers it in writing.
Most Linear swing motor replacements run about two to three hours from the time we park the truck. Slide motor replacements take longer, usually three to five hours, because the chain, sprockets, and carrier rail all need to be inspected and re-aligned. If we determine it’s a same-day job from the phone call, you’ll see the gate operating before dark. Call us at (936) 296-2568 and we’ll give you an honest window before we even look at the gate.
We keep the most common Linear swing and slide motors, motor capacitors, and drive gears stocked on the truck, so the majority of replacements happen same-day or next-day in University Park. If your gate uses an oddball model or an obsolete Linear drive, we’ll order it from our local supplier and set it straight with temporary manual operation in the meantime. We’ll also show you the part before we install it, so you know exactly what’s going on your gate.
