Linear Gate Motor Replacement Nationwide

Linear Gate Motor Replacement: The Missouri City Owner’s Guide

We stock and install Linear-compatible gate motors across Missouri City, and most replacements run between $850 and $1,450 installed, with same-day service available when we have the right unit on the truck. You’ll usually know the motor has failed before we ever show up: the gate hums but won’t move, or it moves a few inches and reverses, or the control board clicks but nothing happens at the arm. The motor itself is the workhorse of the whole system, and in Houston-area humidity it tends to fail at the capacitor or the gearbox first, not the windings.

Linear built swing and slide gate operators under the APeX, MegaCode, and LDO model lines, and most Missouri City homes with an older Linear system are running an APeX or an M3 series unit. The telltale is usually a faded silver or gray control box mounted near the gate post, with the Linear logo embossed on the access cover. If that box is dead or the arm drives but the gate won’t hold position, the motor assembly is the prime suspect. We carry new OEM-equivalent replacement motors and full operator kits for the most common Linear swing-arm configurations, and we’ll photograph the nameplate before quoting anything.

Key Takeaways:

• Most Linear gate motor replacements in Missouri City run $850-$1,450 installed, parts and labor included.
• We keep common Linear-compatible motors on the truck, so same-day replacement is often possible.
• The written price is in your hand before any tool touches the gate. No surprises, no verbal handshake.
• Every replacement includes a photo log and a written record of the part number installed.

Which Linear Models This Applies To

The most common Linear operators we replace in Missouri City are the APeX swing gate series, the LDO slide gate series, and the older M3 and MR models that predate the current generation. Linear changed motor specifications several times over the years, so the part number on the nameplate matters more than the model name alone. We match motors by shaft length, mounting bolt pattern, and gear ratio, not just by “it says Linear on the box.”

When you have a failed Linear motor, you have two honest paths: an OEM Linear replacement or a quality aftermarket equivalent we’ve tested across hundreds of installs. OEM parts carry the exact factory spec and typically a one-year parts warranty. Quality aftermarket motors, when matched correctly, often cost 20 to 30 percent less and hold up just as well in residential use. For a swing gate in the Houston climate, where humidity and heat cycle the bearings harder than most manufacturers plan for, we lean toward motors with sealed bearings and a cast-aluminum housing, regardless of whose name is on the label. We’ll show you both options in writing before you decide.

One compatibility gotcha worth knowing: Linear’s APeX swing motors share a bolt pattern with some older Apex commercial units, but the limit switch wiring is different. A homeowner who swaps in a used part from a different series often ends up with a gate that reverses at the wrong position or won’t stop at all. That’s how we see a lot of “second opinion” calls.

Signs Your Linear Gate Motor Replacement Is Failing

• The gate hums but doesn’t move. This usually means the motor is getting power but the start capacitor has failed, so the rotor can’t kick into motion. It’s the single most common failure we see in humid climates where capacitor seals degrade faster.
• The gate starts to open, then reverses or stops mid-travel. Often this is the motor’s limit-switch timing drifting, but when it happens repeatedly with the same physical position, the gearbox is usually binding and the motor is struggling against it.
• The arm moves but the gate barely does. That’s a gearbox or clutch issue inside the motor housing. The motor is spinning; the mechanical link to the gate arm isn’t. Running it in this state wears the gear teeth down to nothing.
• The control board shows power but the motor won’t respond at all. If the board lights up and the remotes trigger the relay, the motor windings or the internal thermal cutoff have likely failed. This is a part replacement, not a programming fix.
• You smell a hot electrical scent near the operator after the gate cycles. The motor is overheating, which means the windings are breaking down or a bearing is dragging. Houston heat doesn’t cause this on its own; it accelerates it. A bad bearing in humid air is a matter of when, not if.

Replacement Cost & What’s Included

Most Linear-compatible gate motor replacements in Missouri City run from $850 to $1,450 installed. The spread comes down to three things: whether it’s a swing arm or a slide motor, whether we’re replacing just the motor or the motor plus the control board, and whether the existing mounting brackets and arm are still serviceable. A straightforward swing motor swap on an APeX system with intact hardware lands closer to the bottom of that range. Adding a new control board, proximity sensors, or re-mounting an arm that’s been knocked out of alignment pushes it toward the top.

Every price we give in Missouri City is written down before we start. You’ll see the part number, the labor, and the total, and that total is what you pay. It doesn’t drift because the job took an extra hour. The 365-Day Done Right Promise covers every replacement: if it’s not right, we make it right at no additional charge. That’s Haven Standard Clause 3, and we’ve never had to argue with a customer about it.

DIY or Call Us?

What you can safely check on a Linear gate motor: the breaker amperage, whether the disconnect switch is thrown, whether the manual release lever is engaged, and whether the arm bracket has visible hardware missing. Those are the things we’d ask you to look at over the phone anyway. You don’t need tools, and you can’t hurt yourself doing it.

What you shouldn’t do: open the motor housing. A capacitor can hold a charge long after power is cut, and a misaligned gearbox under load can move unexpectedly. We carry the right motor on the truck in Missouri City more often than not, and we’ll match the wiring to your existing Linear board rather than asking you to guess at it. If you’ve already got the cover off and you’re looking at a part number, call (346) 253-1761 and tell us what it says. We’ll tell you over the phone if it’s worth our trip or if you need a new unit.
