Mighty Mule Gate Motor Replacement: The Fort Worth Owner’s Guide

We stock and install Mighty Mule-compatible gate motor replacement parts across Fort Worth, with most swaps running $420 to $780 installed, including the part, labor, and a written one-year guarantee. If your gate stopped mid-swing, hums without moving, or opens partway and reverses, you’re likely looking at a failed motor, a stripped drive gear, or a dead control board. Most Mighty Mule replacements in Fort Worth are completed same day once we confirm the model and have the part on the truck.

Call (817) 840-7067

Here’s what we see most often: an owner comes home, hits the remote, and the gate groans and stops. Or it works fine for months, then one day refuses to open at all. The motor itself is rarely a sudden failure on Mighty Mule units. More often, a worn gear or a failing limit switch takes the motor with it. The good news is that Mighty Mule parts are widely available, and a full motor replacement usually costs less than fighting a dying unit for another six months.

Which Mighty Mule Models This Applies To

We replace gate motors for the Mighty Mule MM260, MM360, MM371W, MM372W, MM562, MM571W, MM572W, MM600, and the older FM200 and FM500 series. The compatibility gotcha with Mighty Mule is that the MM360 and MM371W/MM372W series use a different mounting bolt pattern than the MM260 and FM series, so you can’t always drop a newer motor onto an older mount without an adapter plate. We carry those plates on the truck because we run into it at least once a week in Fort Worth.

To identify your exact motor, look on the underside of the operator housing or on the arm itself for a white Mighty Mule label with the model number. If the label has faded out, check the control board, which usually has the series printed on it. For the OEM-versus-aftermarket decision: Mighty Mule OEM motors are built to match the original arm and gear set exactly, and we keep a good stock of them. Quality aftermarket motors like the US Automatic and AECO equivalents often cost 20 to 30 percent less and perform as well for most residential single-swing gates. We will quote both and tell you the tradeoff honestly.

Signs Your Mighty Mule Gate Motor Replacement Is Failing

  • Gate hums but doesn’t move: The motor is getting power but the drive gear has stripped or the spindle is spinning free inside the arm. This is the most common Mighty Mule failure we replace in Fort Worth.
  • Gate opens partway then reverses: The limit switch inside the motor housing is failing and telling the board the gate has traveled farther than it has. Replacing the motor assembly often fixes this because the limit switch on most Mighty Mule units is integrated into the motor housing.
  • Gate works manually but not from the remote: The motor itself may be fine, but the receiver board or the motor’s internal capacitor has failed. We test the board before recommending a full motor replacement, because paying $200 for a board beats paying $600 for a motor you didn’t need.
  • Motor runs but gate moves slow or jerky: The internal gear train is wearing, or the motor brushes are shot. In Fort Worth heat, Mighty Mule motors that sit in full sun on the gate arm run much hotter and wear brushes faster than shaded units.
  • Burning smell near the operator: The motor windings are overheating. This is the one sign you should not ignore – a motor pulling too many amps can take the control board with it, and then you’re replacing both.

Replacement Cost & What’s Included

In Fort Worth, expect to pay $420 to $780 installed for a Mighty Mule gate motor replacement, depending on which model you have and whether we are replacing just the motor or the motor and arm assembly together. An MM360 motor alone typically runs $180 to $260 for the part, plus labor. A full MM572W arm and motor assembly runs $350 to $500 for the part, plus labor. The range is driven by series compatibility, single versus dual swing, and whether the existing mount needs an adapter plate.

Every quote follows the same rule: the written price you get before we start is the price you pay when we finish. No additions at the door. The labor includes removing the old motor, installing and aligning the new one, setting the limit switches, and testing the full open and close cycle. The one-year written guarantee covers the part and our install work. If it fails inside that year, we come back free.

Typical Installed Pricing in Fort Worth

  • MM260 / FM200 motor replacement: $420 to $520
  • MM360 / MM371W motor replacement: $480 to $600
  • MM572W / MM600 arm and motor assembly: $600 to $780
  • Control board only (no motor): $180 to $280

DIY or Call Us?

Here’s the honest split. You can safely check the basics: confirm the breaker is on, confirm the battery backup if you have one has not died, and visually inspect the arm for obvious physical damage or corrosion. If a tree limb or a Fort Worth hailstorm bent the arm, you can see it from the driveway. If the gate post itself has shifted and the gate is dragging, that is a post repair, not a motor issue, and you should get that looked at before paying for a motor.

Where DIY goes wrong with Mighty Mule specifically is the mounting and limit-switch setup. The motor has to be mounted so the arm travels through its full stroke without binding, and the limit switches have to be set precisely or the gate will either stop short or over-travel and burn out the new motor. We regularly get called to Fort Worth homes where a homeowner or a generalist handyman swapped a motor and the gate worked for a week before the misaligned arm ate the gear. Replacing the same motor twice costs more than calling us once. Call (817) 840-7067 and we will tell you over the phone whether it’s worth a service call.
