MM 500 problemsBy R. lawell
Sorry but the Mighty Mule failed me very soon after the 18 month warranty ended. The gate began to intermittently fail to open unless I pressed the remote 5-6 times so I called MM support. The support was very ineffective and focused on either the problem being 'low power',although I explained I had just installed new batteries for the unit and remote controls, or the control board was bad; and because they don't do board repairs, my only option was to purchase a new control board for hundreds of dollars. End of support.
Being a retired computer technician and amateur PC builder, I decided to solve the issue myself; complicated by the lack of schematics (circuit diagrams) or detailed parts information on the Mighty Mule support page. I ended up replacing the 'mini' 12v 10amp relays on the control board with a heavy duty automotive type 12v 40amp relay w/pluggable wiring harness.
Ola! After a year of messing with this problem, my gate opener opens reliably again.
I feel this was a defective control board with underpowered relays and should have been a'factory recall' issue. MM should have offered a replacement boards to customers instead of expecting us to spend hundreds of dollars to purchase a new board 'compatible' with all MM 500 Gate Openers.

FM500 Install - easyBy Aesop
System is easy to install and configure. After several weeks of operation, I've found that the solenoid operated gate lock overtaxes the batteries about 20% of the time. The symptom is that the gate simply stops partway through a cycle. By using the soft start/stop function, replacing the batteries, setting the solenoid energize time to a minimum and using the two minute close delay, I can generally get the system to work....overall, I'd recommend stepping up to one of Mighty Mule's other, more powerful operators.
Without the drain of the gate lock, the system works very reliably, but I want the security of a closed AND locked gate!

Not bad for the $By R. Monson
I've owned this opener for over 3 years and have it mounted to a 16' farm gate. The farm gate itself is very prone to getting out of adjustment which is a source of most of my pain. I suggest through-the-post bolt hinges instead of lag screw types. This give a much finer grained control over adjustment. Now to the opener. It's fairly easy to install if you're semi-savvy. It does the job exactly as advertised and has never malfunctioned of it's own accord. Technical support is very prompt and professional. Now for the bad part, I've suffered damage twice now from nearby lightning strikes. First I lost my keypad. Then I blew out the main circuit board (that's $250 right there). I intend on grounding both my gate and the wire fencing as well. Other gate openers may suffer from this as well, I don't know. All in all, it's a decent do-it-yourself deal.
