This is our 2nd rev counter replacement in 6 years. Both replacement parts installed easily & worked as expected. Recommend for sure.

Exact limiter you get from Mighty Mule. Set the gate limit the first time. Arrived quickly and great price - not a knock off! Very happy

Installed a mighty mule 350 on a 20' steel red tube gate (312) lbs. In 2009. Replaced the motor inside the actuator in 2014. Used a 12 vdc motor from a cambel & Hatfield portable cordless compressor. (As the compressor pump failed.) The motor is still strong. The rev counter fixed a intermittent problem that if you open the gate all the way until the limit switch is activated the arm gets stuck in that position. Then required me to disconnect the actuator and manually open and close the gate. Not a real problem when the weather is nice. But pulling a 21' trailer out or into my farm on the downside of a hill was dangerous during rush hour traffic. So now my gate works 🤗

Our gate would only move 5 ft. Found some corrosion on this circuit board, replaced it and works great again

I have the same mighty mule 502 gate from 2007. Had an error code that said this needed to be replaced in the slave arm. Swapped it out in 10 Minutes and hopefully will get another 20 years out of this opener. People complain mighty mules don’t work but with proper maintenance there is not much that can go wrong. Pretty simple to open and replace parts as well. It’s basically just a control board, 12 v battery, motor in arm and this rev limit switch. All are easily replaceable if needed. Only thing I’ve changed before this was the battery every few years.

Brought my mm600 et pro back to working order. Stopped closing and would have continuing on and off beeping code. Direct factory replacement part at a good price easy install. Make sure battery good and connections to circuit board are tight before replacing.

Say your mighty mule gate opener has been properly installed and has been working great for many, many months. You get home one day and when the arm is fully retracted, it stops and starts beeping. You hear 3 beeps if it is the master arm malfunctioning or 4 beeps if it is the slave arm. You check to make sure you have not weed-whacked the wiring nor has it been munched by gophers. Chances are the little board pictured above has failed.This circuit board, comprised of a rev counter and a limit switch, keeps your gate opening arm from running away. The problem is that it lives in a hostile, humid environment. Mine failed after some 7,000 cycles and 8 years in a marine spray climate. My guess is that the rest of the gate arm components are sturdier and will go for another 10 years.I looked pretty hard in the internet. While there are many installation videos, I could not find any videos or information on line for the 500/502 heavy duty arm. Replacement of the counter board in the 500/502 heavy duty arm takes about 20 minutes. This is what it involves:First you must turn off the power switch at the bottom left of the control box.You remove the gate arm cotter pins at both ends. Leaving all wiring in place, you rotate the arm upside down and place on a piece of cardboard on the ground. You then remove the 14 screws using a T20 tool bit. Less than 2 minutes with a battery-driven tool.You open the clamshell casing an inch or so and unplug the pin connector cable. Please note the cover does not come off but swings open like a reluctant clamshell.A single, shorter, T20 screw attaches the board to the assembly. You swap the boards, screw the new one in, and re-plug the connector, making sure orange and green cables match the markings on the board.You may also want to clean up any rust, dust and spider webs and shake it all loose. Also, after you get all this accumulated junk out, it is a good idea to put some wire or a small nail through bottom drainage hole to make sure moisture can get out.Since I plan to keep this operational for another 10 years, I put a thin coating of moly graphite grease on the worm gear making sure that any excess got wiped clean so that it does not clog that tiny limit switch on the circuit board.You mount the arm back up lubricating all of the pins, and rubbing points with moly grease and turn your power back on.Or you can buy a new replacement arm from the Amazonians for $262.

We are on our third replacement switch in several years. I am glad hubbie is so handy, and could deal with this,as gate repairs can be costly. The small metal switch arm is the weak link and prone to breakage and failure. When the gate opener works, it works, well, but when it's out of service we must deal with escaping pets and bungee cord closures...Grrr. Glad we found the problem, but these switches are a bit pricey when replacing multiple times. Perhaps a 2.0 design revision is in order?
