Mighty Mule Gate Repair in Plano, TX | Gatewood Fence & Gate
We’re an independent Mighty Mule service provider, not a manufacturer arm, and we handle Gate Repair in Plano every week. What makes our Mighty Mule work different here is simple: we know how Plano’s blackland clay and HOA rules interact with Mighty Mule’s limit switches, swing arms, and control boards, so we fix the actual problem instead of swapping parts until something works. Call (903) 829-4499 and you’ll get Hal or one of his crew, a straight answer, and a price before we touch a wrench.
Why Plano Residents Choose Us for Mighty Mule Service
Hal Gatewood grew up about a mile from Old Town Coppell and has been working gates in this part of North Texas since 2001. He picked up the trade fundamentals at Tarrant County College’s vocational program, then learned the rest on job sites dealing with Texas heat and gates that hadn’t seen a wrench in fifteen years. These days, folks around Plano know him as the guy who shows up on time, tells you straight what’s wrong, and doesn’t charge for parts you don’t need.
We’ve been at this for over 29 years as a company, owner-operated the whole time. We service Mighty Mule because homeowners in Plano’s master-planned subdivisions bought these operators by the thousands, and most of them are now hitting the age where boards fail, swing arms seize, and limit switches drift. We carry Mighty Mule sales & service parts for the FM and MM series, and our techs work from the brand’s diagnostic error codes rather than guessing. Every job carries our 90-Day Done Right Promise in writing. If it’s not done right, one call brings us back.
Common Mighty Mule Gate Repair Problems We Solve in Plano
- FM200 control boards losing limit memory after power surges. Plano’s summer thunderstorm season brings close lightning and grid flickers that hit low-voltage control boards hard. An FM200 that forgets its open and close limits right after a storm usually has a surge-damaged board, not a bad motor. We test the board before recommending replacement.
- MM360 swing arms seizing at the pivot pin. When Plano’s blackland clay heaves a gate post, the swing arm takes constant side-load it was never designed to handle. The pivot pin binds, the motor grinds, and the gate stops mid-swing. We re-plumb the post, replace the pin, and re-set the limits so the operator isn’t fighting the foundation.
- FM350 low-voltage wire runs chafing against brick columns. Plano’s brick masonry gate columns crack at the mortar joints when the clay subgrade shifts. That leaves sharp edges rubbing against the 24-gauge wire running to your keypad or photo eye sensors. A short here will trip the board intermittently, which is why we always inspect the full wire path on FM350s.
- MM371W battery backup failing after hard freezes. Winter Storm Uri in February 2021 exposed a weakness in these units: the sealed lead-acid backup battery doesn’t recover from sustained sub-freezing temperatures. If your MM371W runs on battery but won’t hold a charge after a cold snap, the battery is done, and sometimes the charging circuit went with it.
- Gates dragging on the latch post after spring rains. In Plano, the clay swells in April and May, posts heave, and the gate leaf drops just enough to catch on the latch post. The operator’s limit switches then throw an error because the gate never reaches its fully closed position. This is a post problem first, an operator problem second.
Mighty Mule Service in Plano: What Local Conditions Mean for Your Equipment
Plano’s blackland prairie clay swells more than the sandy loam of neighboring Richardson or the limestone bedrock of Frisco. That matters for Mighty Mule owners because a swing gate post that drifts three-quarters of an inch after spring rains will usually need re-plumbing before the operator’s limit switches can work reliably. A generic gate guy might reset the limits and call it done. Two months later, the post has moved again and you’re paying for the same service call. We’ve seen this cycle play out in neighborhoods along Hedgcoxe Road and in the Estates of Willow Bend, where brick columns crack, mortar crumbles, and the gate hangs just enough out of plumb to trip the Mighty Mule’s error codes. And in Plano’s HOA-heavy corridors, you can’t just pick any fix: architectural review boards have rejected repairs using the wrong powder-coat color code or a hinge style not on the approved list, forcing homeowners to redo work at their own expense. We photograph everything before we start, because we’ve learned which details the HOAs actually check.
Mighty Mule Models & Products We Service in Plano
We work on the FM200, FM350, MM360, and MM371W, which covers the vast majority of Mighty Mule operators installed in Plano from the early 2000s onward. Our parts approach is honest: we install genuine Mighty Mule OEM boards and motors when the unit is under normal wear, but we use heavy-gauge aftermarket hinge bushings and stainless fasteners where the brand’s stock hardware is undersized for Plano’s shifting clay. We keep common boards, limit switches, and swing-arm hardware stocked for fast turnaround across Plano, and for FM200 units over 10 years old with failed boards, we’ll give you a straight repair-vs-replace quote - or our Gate Installation in Plano - rather than selling you a new board that will die again in two seasons.

FAQs - Mighty Mule Gate Repair in Plano
The clay under your gate posts has swollen with the rain, heaving the post and dropping the gate leaf just enough to catch on something or trip the obstruction sensor. We re-plumb the post first, then re-set the limits. Call (903) 829-4499 and we’ll diagnose it free.
Usually just the board. If your FM200 is under 10 years old and the motor still runs, a board replacement gets you back in service. If it’s older, we’ll quote both options honestly. Estimates are free.
Plano’s hard freezes destroy the sealed lead-acid backup batteries in MM371W units, and sometimes the charger circuit goes with them. We test both and replace only what’s failed.
Not about the opener itself, but they do care about the gate’s appearance, hinges, and color. In neighborhoods along Hedgcoxe Road and in the Estates of Willow Bend, HOAs have rejected repairs for using the wrong powder-coat code or non-approved hinge style. We photograph and match HOA specs before we start.
The most likely culprit is a pivot pin that seized from ice expansion, or a control board that took a voltage spike during the freeze-thaw cycle. We diagnose both on one visit and give you a written quote before any repair begins. Call (903) 829-4499 and we’ll get you sorted.
