Mighty Mule electric gate repair in Fort Worth typically runs $180 – $340 for most opener and control board issues, and we can usually diagnose the problem on the first visit. We’re Calder Gate Repair Fort Worth, an independent Mighty Mule service provider, and we work on every series from the old FM350 swing openers to the current MM series and the GTO/PRO models. If your gate is stuck open, stuck shut, or just won’t respond to the remote, call (682) 432-9830 and a live person answers, day or night. This page is for Fort Worth homeowners who own a Mighty Mule and want straight answers about what’s wrong, what it costs, and how fast we can get it fixed.

How Mighty Mule Products Fail – and How We Fix Them
Mighty Mule builds a decent residential opener, but after years in Fort Worth heat and dirt, we see the same failures repeat. Here are the five most common, and what we actually do about them.
- MM371W and MM372W control board burnouts after storms. Fort Worth gets real lightning, and these boards have minimal surge protection built in. The gate works fine for months, then one storm and nothing. We replace the board and add an inline surge suppressor so the new one doesn’t die the same way. Mighty Mule’s own site won’t tell you that second step, but it’s the difference between a one-time fix and a repeat call.
- FM350 and FM500 swing arm motors that run but don’t move the gate. This is usually a stripped plastic drive gear inside the actuator housing. It happens more with long, heavy gates or gates that get pushed by kids and wind. We can sometimes replace just the gear, but on motors over eight years old we level with you: a new MM series actuator usually makes more sense than pouring money into a tired housing.
- GTO/PRO series remote receivers that lose programming on their own. The receiver memory on these is small, and power flickers from Texas storms can wipe it. The remote still has its code, the opener just forgot it. We reprogram, and if it recurs we add a small battery backup to the receiver, which solves it for good on most Fort Worth installs.
- RB741 and RB791 gate arm slippage on chain-drive openers. The tension loosens over time, especially with temperature swings between a Fort Worth freeze and a 105-degree July. The gate starts to sag, then the opener overloads trying to move it. We reset tension, align the gate on its hinges, and set the force limits so the motor isn’t fighting itself.
- MM260 and MM262 keypad and safety sensor failures after heavy rain. The keypad on these models is rated for outdoor use, but the seal eventually gives. Water gets in, keys stop responding, or the gate refuses to close because the sensor thinks something’s in the way. We replace with a sealed keypad and reposition the photo eyes so the reflection off wet Fort Worth concrete doesn’t trigger false stops.

Our Mighty Mule Electric Gate Repair Process
Here’s what happens when you call us about a Mighty Mule gate that quit on you. No mystery, no waiting around all day.
- 1
You call (682) 432-9830. A live person picks up, asks what the gate’s doing, and schedules a time. You get a trackable arrival window, same kind of thing you’d get from a rideshare app.
- 2
Our tech arrives and listens. Before we open a single panel, we have you show us what it’s doing, or not doing. Nico Alvarez grew up learning this trade at Los Angeles Trade-Technical College, and his rule still applies: “Tell me what it’s doing – or not doing – and I’ll tell you exactly what it needs.”
- 3
We diagnose with the multimeter out, not a guess. We check voltage at the board, test the transformer, cycle the actuator, and watch the limit switch behavior. We don’t replace parts on a hunch.
- 4
You get a written price before we touch anything. This is not optional with us. If it’s a simple fix, great. If it needs a board or actuator, we quote OEM and quality aftermarket options with real pros and cons. You pick. The number on your quote is the number on your invoice.
- 5
We fix it, then test it hard. We cycle the gate at least ten times, check the safety reversal, reset force limits to factory spec, and verify every remote and keypad in the house. Not just the one you handed us.
- 6
You get a written guarantee and a digital invoice. Every Mighty Mule repair carries our 365-Day Done Right Promise: if it fails within a year, we come back free. You pay from a link. That’s it.

AfterWhat Mighty Mule Electric Gate Repair Costs in Fort Worth
Here’s what Fort Worth homeowners can expect to pay for common Mighty Mule electric gate repair scenarios, before parts:
- Remote or keypad reprogramming: $85 – $135
- Safety sensor replacement: $120 – $190
- Control board replacement: $220 – $340 (boards run $110 – $180 for Mighty Mule depending on series)
- Actuator or swing arm motor replacement: $280 – $420
- Full opener replacement on an existing gate: $450 – $750 installed, depending on gate size and whether the mount needs reworking
What moves the price: gate weight and length, whether the post mounts are still sound, and how old the wiring is. A 1998-era system with crusty wire and a rusted post will cost more than a 2019 gate that just needs a board. Estimates are free, and you’ll always get the number in writing before we start. Call (682) 432-9830 for an exact quote on your Mighty Mule.

FAQs
No. As an independent Mighty Mule service provider, we are not authorized by the manufacturer, and our repairs do not void any existing warranty if the issue is unrelated to the component we service. If the opener is still under warranty, we’ll tell you before we touch it, because sometimes the cheapest fix is a warranty claim you can file yourself. When we do work, the 365-Day Done Right Promise covers our labor in writing.
Most Mighty Mule repair calls in Fort Worth are scheduled within 24 to 48 hours. If your gate is stuck open and your dog is loose or your car is trapped in the driveway, tell the person on the phone, and we’ll do everything we can to get someone out same day. Call (682) 432-9830 and describe the problem, and we’ll give you a straight answer about timing.
Usually, yes. For MM series and current PRO models, we keep common boards, sensors, and remotes on our trucks. For older FM350 or GTO/PRO actuators that Mighty Mule has discontinued, we source OEM parts from our supplier network, which typically arrives in two to four business days. If there’s going to be a wait, we tell you before you commit to anything.
If your opener is under seven years old and the failure is a single board or sensor, repair is almost always the smarter money. If the actuator is shot on a 10-year-old FM500 and the control board is also showing corrosion, we’ll tell you straight that replacement costs less than two separate repairs. We’ll show you the numbers for both paths and let you decide. Call (682) 432-9830 for an honest read on your specific setup.
