You sir are eloquent, educated and creative! Thank you so much for the help. I will be searching for the motor upgrade next, I hope you succeeded, as mine is so slow!! Cheers
This is an excellent tutorial. Thank you for sharing your knowledge and tips! I especially appreciate your last point of having pivot end of opener slightly higher than the end that attaches to get. I live in a rainforest with 200+ inches of rain/year and I certainly don't want water in the housing!
Have had three 350 gate openers They are really bad for blowing the main circut board,Tryed to get a new board from mm and said they are no longer avaible .THANKS ALOT MIGHTY MULE.
I agree, these economy openers are almost disposable. There are a couple of components that seem to blow on the main boards, and they usually blow when the opener strains and pulls a bunch of amps. I need to make a follow-up video explaining what to do in that case.
Thanks Jake! The funny thing is - my neighbor has an old Mighty Mule opener, the type with the controller separate from the arm - and his arm is much faster at cycling!
I have model 271, it would open like a few feet then beep & stop. After disassembly i found the motor housing full of ants and larva. The larva were being pulled into the limit switch. After cleaning everything real good it works!
Yesterday morning my gate arm started to have the same issue. It wouldn't open or close and the gate arm had the same beeping pattern. I took it apart and followed all of the instructions in your video, there was quite a bit of water and moisture in the casing as I was taking it apart I was finding more water in each area. I dried everything out and let it set out to dry overnight, I put everything back together today but it's still not working, still beeps in the same way. Do you have any other suggestions for me to try? This video was the best result I could find online for this specific issue so I am hoping you might have some additional advice or tips for me to try. I hope you see this comment! Thank-you so much for the video by the way! It was incredibly helpful and informative and made me feel comfortable taking this gate arm apart as I have never tackled doing it before.
I'm sorry I'm just seeing this comment now. Did you ever get your opener fixed? Did you check therev counter board IR emitter / detector area for water?
@@normnelsonHello! I did eventually get it working but then it failed on me again. Now I am having another issue. I came back to your video to find that you just responded to me an hour ago. Talk about some good timing! My old arm needed to be replaced and today I am actually going through the process of installing another arm. Upon hooking up power and powering on the device, it’s a constant loud alarm sound coming from the arm. Any suggestions?
Hey man I got a problem with my gate cause my mule gate closes when I hit the bottom to close but opens back up once it finishes beeping on its own. Do you have any suggestions?
I have a situation where I open the gate, and after a period of time it starts creeping back to the closed position. Not sure if this is common or can be corrected. Any suggestions? Thanks
My gate keeps opening and closing by itself and I can’t get it to stop. I live in the desert southwest, so moisture is not an issue. We have had temperatures 100 degrees plus for days. I don’t know if that could cause problems. My husband died a few months ago and I am not mechanically inclined, so I have no idea what to do. Can you make any recommendations or suggestions?
Sorry, I'm just seeing this comment now. My first thing to check would be if your gate has a wireless remote and if there is new wireless interference from some other source... so if you have a wireless remote, I would change the code on the remote... there are instructions online for this, normally it's a small set of switches inside the remote, and then you press a button on the main board of your gate for your gate to "learn" the remote code... but this varies by gate model / manufacturer. So I would download the manual for your particular model and see how that works on your model.
@@normnelson - that is exactly what I did. Those mud wasps ended up shorting out the round alarm/audio component. I sent this info/pix along to Nice/Mighty Mule for product enhancement consideration for those of us who live in the NW or areas where these critters thrive. Silicone and a bit of screen works great. BTW - great video!
Thanks. There is no zerk fitting or anything, but you can lube the Acme screw directly when you have the opener apart, then cycle the opener to grease the areas you missed.
Glad you liked my video - let us know how your repair goes. My opener has been 100% trouble-free since I did this mod just over a year ago... it made it through snow, sleet, freezing weather this winter... not one problem.
Excellent, after much rain and deep freeze, the gate developed issues like you described. Warmer, it would work with stops. I was, am getting water drips when turning the on/off switch. This video is a great one as you show exactly how easy it is to service and also seal. The add-on of slanting for a water run is a good idea. Will probably try to repair before buying a new one.
Can you do a video on the gate latch at the other end of the gate. Mine is not working correctly. It opens and then closes before the gate can open. Thanks
Glad you enjoyed it! I don't want to jinx myself, but our gate has been working flawlessly since I did this repair / mod., and we've had lots of sub-freezing weather, snow, lots of rain too.
I'm not sure whether you're talking about the "top" of the circuit board as it looks once you take the cover off... that is actually the bottom of the board once the gate opener is installed. I will say that as I've shown it in this video, with the cover off, looking at the bottom of the unit... the red and black wires that you can see connect there go directly to the motor. The red and black wires underneath the circuit board (closer to the inside of the unit) go to the power switch. Does this help? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DuddDiTF5nY.html
Thanks for video. What bit did you use for top center? I noticed you switched to another bit but couldn't tell what.. Mine is clogged with bug mud and I can't visualize the head.
That's still just a torx bit for a torx screw (I can't remember if they're T-20 or T-25, but they're all the same), but I added an extension for that one screw because that one screw is further down a small hole.
Make sure the wires are connected to the correct terminals on the switch, (depending on the switch, you could have normally-open and normally-closed reversed) then the problem is in your circuit board.
Yeah, definitely a half-donkey job of water proofing. The good news is that (I don't want to jinx myself) since I did this fix / mod, this opener has been working flawlessly in all sorts of freezing, snowing, sleeting, fogging, rain, rain and more raining weather....
Do you mean the part on the arm, or the part actually attached to the post? Here is a bracket set for the post: gateopenerking.com/store/bracket-set-350ih-2-qty-351ih-352ih-353ih-sw1000-mm700.html?gclid=CjwKCAiAhKycBhAQEiwAgf19esr3xUpnF9n-A3wnHOlLbG82NK-ylHjidk6eWHwgZuEEMYId0YKE6xoCkUgQAvD_BwE
It’s the molded aluminum part that is part of the main motor housing that attached to the stainless steel brackets on the post. It’s an internal part that connects with two short bolts to the motor housing. It has two parallel tongues that bracket the metal piece I had to weld to the post. I’ve looked everywhere for this part. No luck….
@@theoh6260 I believe they only sell (or sold) that as part of a kit. You might try searching for "Mighty Mule rear mount kit R4430". I see one supposedly in stock in Canada? www.jokmamu.shop/index.php?main_page=product_info&products_id=82846
I don't know for sure since I haven't disassembled a MM371, but it's likely a 550-sized motor. Both 540 and 550 sitzed motors are 36mm in diameter, but the 540-size motors are usually 50mm in length, while the 550 motors can be 55mm to 90mm in length. I recently repaired a small reciprocating saw (Makita knockoff) and the RS550 motor in it was 57mm long, which is pretty typical.
Too bad Mule spent no effort keeping water intrusion to a minimum. Ants and water kill these long before you get your moneys worth. Garage door opener works for years with no issues.
I think the seal seam at the bottom is best. The only other way to make it better is to split the seal the long way and put one seam at the top and one on the bottom.
I've had no problems at all with this opener since I sealed it up well. It's currently freezing weather here, snow and ice and it's still running strong!
@@gilwilforbes Exactly. I made mine a raincoat out of 40mil Oatey gray shower pan liner. Fold it over the top and joined it together at the bottom with three small bolts (along the length, back, middle, shaft end) with wingnuts. Has lasted out in the sun/weather for over 3 years now, hasn't deteriorated.
@@normnelson Did you happen to do any water sealing around where the (power/accessory) wires come into the unit (would be opposite side of where the arm extends/contracts)? If you slightly raise the unit as you noted (so it is higher where the "L" shaped bracket is at, the issue now is that water will come into where these wires enter the unit. While there is a very small escape hole on the very bottom for this water, there is a lot of water and condensation buildup in there. Was thinking to either silicone this area or use plumber putty or something - have you done anything for this by chance?
Mighty Mule is a garbage opener. I had to stop buying them because I was having to replace them every year and the last one only lasted 6 months. Be aware! Customer service is non existent...
