Mighty Mule Gate Opener - Trouble shooting

[Stan R]

Do you still have the book.

You might try re programming it??

Mine is going on 3.5 years but only used about 1/2 the week

Have you adjusted the sensor that stops it when it hits something, mine does this in cold weather or strong wind sometimes, adjust the sensor to the highest setting and grease the hinges with thinner grease or oil and give it a try.

This. It was happening to mine. Also, silicone spray on the inner part of the arm to clean and lubricate.

Yup yup. Silicone spray on the arm and play with the stall force setting. Hope it starts working for you quickly.

Thanks, Stan and everyone else. Yes, I still have the book and was wondering if I should try to reprogram or look at fuses or the lubrication. Looks like I'll start simple and I may get to reprogram it.

Not trying to rub salt in the wound. But the best thing you can do I throw the MM in the trash and get an Apollo!

[Dusty Britches]

That's not an option - unless you plan to give me $1600 to replace my current system. It is either fix this one or hire Tatoo to operate the gate.

This is true.....

Have you tried replacing the battery? I know, we went thru this last time....

Buy one at Wally World and try it. You can take it back if that's not the problem

Oh I understand, I wanted one for years before we got it.

BAM!! Rod - go back to START! Yes, we replaced the battery and even tested it.

I must have missed the replaced it part.....I meant this year

I just know that interstate will tell you a battery is good even when it isn't.

Things you learn on the road.....

[Dusty Britches]

I hear ya. Except the Interstate store didn't test it the second time.

I have a mighty mule gate opener that was working but being a --- sometimes. Only used it about a year or so before removing an storing it. It's a model 500.
If you could use this pm me your mailing address an I will send it to you.

I had a similar issue with one of my clients gates and ended up replacing the battery, if there is even a small difference in voltage and amps, gate opening was iffy at best.

We had one doing the same thing but it was an Apollo. I started looking at it and found one of the wires had a bare spot up against the electric motor on the gate itself.

[Dusty Britches]

lameduck - I'm on that like a duck on a June bug. I sent you a pm.

I appreciate everyone's comments. Rudyl - you are correct, anything less than 12 amps will shut it off.

I love my mighty mule. It's kept right on working even when it's gotten down to -15 here. I have my on a 12.5 w of solar and it just keeps on rocking. The only time I've had a problem like what you're describing was when the wind has blown so hard it triggers the sensor. I did what was suggested earlier and turned the sensor down all the way, now no issues.
