We repair Mighty Mule gate operators across Claremont, 91711, as an independent shop offering our Electric Gate Repair in Claremont and working on these systems long enough to know their FM, MM, and solar models inside out. Most of the Mighty Mule failures we see in Claremont trace back to two local realities: the city’s historic wrought-iron gates with non-standard mounting geometry, and the freeze-thaw-dry cycle that wreaks havoc on wood and hinges here. If your Mighty Mule gate is reversing mid-travel, stalling, or dead after the last Santa Ana stretch, call (866) 304-1321 for a straight diagnosis.
Lexington Gate Repair is not a general handyman service that also does gates.

This page is for Claremont homeowners and property managers who need a Mighty Mule operator fixed correctly, not guessed at. You can reach our Mighty Mule sales & service line for questions about any model.
Why Claremont Residents Choose Us for Mighty Mule Service
Nelson Arquette, owner of Lexington Gate Repair, grew up off Eucalyptus Avenue and has spent the better part of three decades working on gate systems across the Inland Empire. He learned the mechanical and electrical side of the trade through the Electrical and Industrial Technology program at Chaffey College in Rancho Cucamonga, where hands-on troubleshooting was the entire point. These days he works exclusively on gates: operators, hinges, control boards, safety loops, the whole system.
That matters when your Mighty Mule acts up. A lot of Claremont gates are original to the property, which means a tech who only knows new equipment will misdiagnose the problem. We know the difference between a bad control board and a sagging hinge that is fooling the board into thinking there’s an obstruction. “If I can tell you what’s wrong before I touch it, we’re already halfway done,” Nelson says. In Claremont, that means we show up knowing what a 1920s wrought-iron gate does to a modern operator arm.

Common Mighty Mule Gate Repair Problems We Solve in Claremont
Here are the Mighty Mule failure patterns we see most often in Claremont, most of them tied to local conditions rather than the equipment itself:
- Control-board and battery failures on solar and battery-backup units. Claremont’s summers are hot and dry, and a Mighty Mule battery mounted in a metal control box on a south-facing masonry post cooks in that heat. By August, boards have baked and batteries won’t hold a charge. We replace them and, where possible, relocate the box so it isn’t working against the climate.
- Limit-switch and arm drift on warped gates. Santa Ana winds and dry heat warp wooden gates and loosen wrought iron. The Mighty Mule arm gets pushed past its set limit and the gate reverses or stalls halfway. Resetting the limit takes ten minutes; realigning the gate so it stays set is the actual job.
- Sticking and binding gates overloading the operator. Winter rains swell Claremont’s wooden gates. Summer desiccates them. Both conditions force the Mighty Mule operator to work harder, and the obstruction sensor interprets that resistance as a person or a car. The operator isn’t broken; the gate geometry is.
- Wireless keypad and remote dropouts. Claremont’s older homes have thick stucco and masonry gate posts, and exterior control boxes on those posts collect moisture and corrosion. Keypads lose programming, remotes fail, and intercom receivers get staticky. We repair or replace these with weather-rated parts that survive a Claremont winter.
- Dead operators after a power surge. Claremont’s above-ground utility lines mean voltage spikes during fall wind events. A Mighty Mule control board is a common casualty. We typically find the transformer and board both need attention, and we handle the repair without turning it into a full system replacement pitch.
Mighty Mule Service in Claremont: What Local Conditions Mean for Your Equipment
If you own a historic home near the Claremont Colleges, you already know your gate is not a standard installation. The posts are often original hand-forged wrought iron set in masonry, and the mounting surfaces were never designed for a modern arm operator like a Mighty Mule MM360 or FM350. That means replacing a limit switch or remounting a sagging arm requires working around irregular, non-standard post geometry. It also means the city’s historic preservation review can require matching profiles when a hinge or latch must be replaced. A generic Claremont Gate Repair service call does not account for any of that. Our call does. In tract-home Claremont, a gate post is a gate post. Around the colleges, every job is a custom fit, and we have rebuilt enough of them to know what the city will and won’t allow. That is the difference between a repair that lasts and one that gets flagged or fails within a season.
On a craftsman home near the Claremont Colleges, a homeowner’s Mighty Mule swing operator had started reversing halfway open every afternoon. Our tech found the original wrought-iron gate had sagged and a hand-forged hinge had worn, throwing the arm past its limit. We realigned the gate, freed and lubricated the hinge, reset the Mighty Mule limits, and replaced a weak battery so the operator stopped tripping on obstruction sensing. The board was fine. The gate was the problem. That is Claremont repair in one job.
Mighty Mule Models & Products We Service in Claremont
We work on the full Mighty Mule line common to Claremont driveways and pedestrian gates: the FM200 and FM350-class DIY slide-and-swing units, the MM360 and MM560-style arm operators, slide gate operators for wider driveways, and solar or battery-backup accessories, wireless keypads, and receivers. When a unit is worth saving, we install genuine Mighty Mule control boards, arms, and batteries. For commodity parts like remotes, keypads, and limit switches, we use proven aftermarket replacements that perform identically without the OEM markup. We stock the most common Mighty Mule parts locally so Claremont repair turnaround does not depend on a shipping delay.
Claremont sits in the Claremont service area we cover directly, and we know which Mighty Mule models were popular in which decade of Claremont housing stock. That familiarity means faster, more accurate diagnosis.

FAQs – Mighty Mule Gate Repair in Claremont
In almost every case we see, the gate has warped or sagged and the Mighty Mule arm is being pushed past its set limit. Claremont’s dry summers warp wood; winter rains swell it. The obstruction sensor reads that resistance as an obstacle and reverses the gate. We realign the gate, reset the limits, and the operator stops misbehaving. If that doesn’t solve it, the control board or battery is next in line. Call (866) 304-1321 and we’ll diagnose it.
Yes, with some work. The posts and gate are irregular hand-forged iron, not the square powder-coated steel Mighty Mule assumes when it ships its brackets. We fabricate or adapt mounting hardware to fit the post geometry, and when a hinge or latch must be replaced, we match the profile the city’s historic preservation review expects. We have done this on multiple craftsman and Spanish Colonial Revival properties around the colleges.
Usually the battery. Claremont’s summer heat bakes the battery inside the control box, and once a sealed lead-acid or gel battery has been cooked, it cannot hold a charge. The panel is typically fine. We test the charging circuit, replace the battery with one rated for high-heat exposure, and relocate the control box when it sits in direct southern exposure. Call (866) 304-1321 and we’ll test it before you order a new panel you don’t need.
We stock the most common Mighty Mule control boards, arms, batteries, and remotes for the FM and MM model families. For less common parts, we source them directly and can typically have them in hand within a few days. We will not leave a Claremont gate inoperable while waiting on a part when a temporary fix is possible.
If the operator is five years old or less and the gate itself is sound, repair almost always makes more sense. If the operator is a DIY FM200 that was undersized for a heavy double-leaf gate and has been failing repeatedly, we’ll tell you plainly that a correctly matched operator is the better spend. We don’t upsell replacements. We make the recommendation we would make for our own gate. Call (866) 304-1321 for an honest read.
