New Rig Same Problem

[shorthauler]

Well after waiting 5 weeks for our dealership to reopen we finally picked up our new 2020 3120. After we got it home the auto leveling system would not work and by the next day nothing hydraulic would work. The dealership sent out a mechanic to manually raise the rig so I could hook up and take it in. He also had to manually bring it the large slides. They found the motor was bad, ordered one and yesterday I picked it back up. That took two weeks. When I hit auto level this time the motor would spin but none of the legs would move. It's going back in today. The batteries are fully charged 13.5 going down to 12.2 when trying to operate the system. Sometimes when trying to raise the front legs the motor runs normal for a few seconds, sometimes it barely moves and sometimes it just starts to move and clicks like a dead battery sound but the batteries are good. I also sometimes get a flickering on the panel screen. I'm thinking a short somewhere but I'll let them figure it out. Next time I pick it up I will do the auto level before I hook up. That was my mistake yesterday. Hopefully it will get fixed and we can start enjoying it.

Make them change the 50A self resetting circuit breaker to an 80A breaker per Lippert bulletin.

Download the MyLCI app from Google play store. Lots of good info, TSB, manuals and troubleshooting are available on the app. Everything at your fingertips.
The LCI tech bulletin regarding this is in the App.

Thanks I'll try that. I can't even hook up today, I have 13.4 volts on the display but only get a click when I press the pad. This is what happened two weeks ago and they had to replace the motor. Now I haver to call and have them send out a mechanic so I can take it in. Luckily the dealership is only about 10 minutes from our house. We didn't get any tools or bits for manually raising the legs.

Daryles,
I can’t seem to find the correct app, we too have had issues with auto leveling, so would like to learn more. I have downloaded the app, but can’t seem to find anything, it’s like they have changed the app, from a few years ago. If u can give me any help it would be appreciated. Sandy

I just checked mine. I see what you mean. Mine must have done an update. It used to have a menu list. Now the menu is in pictures. You have to fig around a bit the info is still there. What in particular are you looking for?

If you can plug it into shore power it might allow the breaker to reset and get you hooked up. Our 3790RD would work okay on shore power raising and lowering or putting out slides but even with two 12V batteries it would trip the 50amp breaker everytime. I changed it to the 80amp and never had another problem. We just bought a 3120RL and are in the process of emptying and cleaning up the 3790RD to trade in. Loved the room and storage in the 3790 but don't need the room all winter in Florida now as we bought a Park Model in our park. No more towing a 42ft 5er to Florida for the winter... Looking forward to only 35ft getting into fuel stations.... Hope you have your issues straightened out for you... I'm not looking forward to all the repairs I have to do with the new unit coming but it is a necessary part of buying new rv's in this day and age. They don't make em like they used too...

Thanks for the info, I was plugged into shore power with no luck. So it seems like maybe one of three possibilities:
1. A second bad motor (what are the odds)
2. A short or bad ground in the 12V system (highly likely)
3. A bad control module (pad)

If the thunder and lightning stops I'll get it in today, otherwise Monday

I doubt if any of us got the 1/4" allen bit for manually moving the hydraulic landing gear or slides. They are easily sourced at ACE hardware, Lowe's Home Depot, some auto parts stores on the cheap. You'll need a good cordless drill as well as another small allen wrench to open and close the needed solenoids. I'd suggest you go to the Lippert website, download, and study the procedure to manually move your landing gear and slides so you won't have to be at the mercy of your dealer or a mobile RV tech. Many of us have practiced the procedure for those just in case moments during ownership.

That is one of the few things I prepared for. Bought the 1/4 inch hex set, a new cordless impact driver and dug out of my tool box an extra Allen set. Been reading a lot of postings on this site and trying to be ready for problems like this. Didn't want to get stuck in a campground not being able to hook up.

I must have yours. There were 4 of them in my blue bag this time.

Yet another post that makes me think twice of ever letting go of my older/perfectly functioning 2011 Montana.

Had a few problems with my 2012, only minor diy on my 2017, and only 1 plus a taillight recall on my 2018.5. The Cedar Creek Champagne 2014 was nothing but problems. It took nearly 2 1/2 years to make it tradable. The difference between the 12 and 17 was huge and very nice between 17 and 19. Without a sense of adventure life is boring. 😄

Went to the service center Thursday and watched the auto level system work, they replaced the motor, pump, and reservoir assembly all as one unit. Drove home, unhooked, and when I hit auto level I got the same error message: (Jack Timeout). I could lower and raise all the legs but not use auto level. Went to hookup the next morning and nothing worked, all I got was a click. Tried to raise the legs manually and they wouldn't move so we jacked up the front end with two floor jacks so I was able to hookup and take it back in. If they don't get it fixed correctly this time they are getting it back. Took delivery on May 11th and it's been non usable and we are coming up on a month.

I had my motor go in less than 6 months. If using a drill to manually operate the motor, be sure to open the appropriate valves before doing so. The lippert manual does not tell you this. All it says is to insert the hex bit into the end of the motor and turn on the drill and that it may take a while. I ended up ruining the valves but luckily was covered under warranty when the motor was replaced.

[shorthauler]

Good advice everyone but I've done all of them and now they are telling me the 4th motor is bad and after the new one arrives and they install it they will start looking for what is causing the problem. Maybe the converter, they are thinking. When I hook up to shore power the microwave will flash like it's supposed to but when I go back inside a short while later it's not flashing so no power. The legs would go up and down with the control panel but by morning the system was dead (battery at 12.4) microwave not lit and could not even raise the jacks with a 1/4 hex and we had the valve turned (already had to use that method twice). So tomorrow will be one month since we bought it and who knows when we'll get to use it.

It sure would be nice if you included a link to the document(s) you mention. I am very computer literate and finding anything on that Lippert site is a nightmare. I tried searching on 'manually move your landing gear and slides' and found no useful information.

There are several LCI manuals saved here on the MOC in the Files section. This is a link to one where the manual operation is described on page 14

The second time the leveling system would not work we had 13.5 volts from the batteries and then we jumped them just to make sure and still nothing. The nose was always up when we tried auto level and the first thing that would happen is the nose would come all the way down while the readout on the screen would say grounding jacks please wait and after about 30 seconds error jack timeout. The last motor to go out was working in the evening but died overnight so something must have been shorting it out during the night. It's a head scratcher!

Have also checked the connections many times, everything seems good.

I found a document on another forum that has step by step instructions for manually operating the hydraulic slides and jacks. It was written by a guy with an Alpine RV but is applicable to a Montana.
