Lippert auto level and hydraulic slide outs proble

[Pugtracker]

Bought new 2014 3850fl first year all good. Now when on battery or plug into 50 amps the slides stop or the auto retract stops when bringing it all in. The breaker trips and resets in about ten seconds. Does not happen when setting up only retracting or bringing in slides.

1. Any ideas?
2. Is this a keystone or lippert issues
3. Anyone else have a 3850fl with this issue.

you will find this problem all over this forum. do a search for 80 amp breakers. The short story is replace the 50amp resetable breaker with an 80amp or two 40amp breakers in parallel.

That wifi fix it. Worked for us.

We do have a 3850, and yes, we were having the same problem. As mentioned above, I replaced both auto-reset breakers (back of battery compartment and replacing both is probably overkill, but they are relatively cheap) with 80 amp auto-reset breakers and have not had an issue since. There are many posts as to the replacement breakers and sources. Based on forum input, we purchased ours at:


Auto reset breaker

It is an easy install and a priceless fix!!

We have a 2012 3585SA and previously had a 2008 3400RL and have never had this problem. Current Monty does have the Level Up system.

We had the problem as soon as the weather got cold. Keystone replaced the breaker with an 80amp under warranty.

We've had the same problem with an SOB, too small a auto-reset breaker installed.

Until you replace the breaker, just bring in your slides and retract your level up while still connected to shore power and you shouldn't have an issue. That is what we do. Good luck.

I guess we've been lucky. The only time the slides or landing gear has stopped on our 2013 3402RL is if the battery is in a state of low charge. The second to last thing we do when packing up is as Metamorphosis stated. The shore cord is disconnected only after everything is retracted. Then I lock up and check lights on the way around.

I had to put in the 80 amp breaker as so many others have and no problems since. My large slide draws 53 amps to get it going according to my Trimetric. Repeated trips on the 50 amp breaker causes it to get weaker and weaker and therefore it stops more often while retracting any one of the slides.

Is there a way to tell what the amperage is on the existing breaker?

[rohrmann]

If your breaker looks like the above photo, it will be no larger than 50 amps. The breaker that is being used to replace it looks like the following photo. There is also an auto-reset version of this breaker, but it hasn't been reported as being necessary.

ITS A 50 AMP I TALK TO THE TECH. He stated that you needed 12.6 volts constant on battery as the system uses the battery to operate. Not the shore power even n if hooked up. Sor not sure if I'm going to go to a 80 or get a better battery.

I can assure you that the 80 amp breaker will fix your problems. It is a widely adopted fix that is a lot cheaper than purchasing a battery and finding that you still have the same problem. Your call!

Don't believe all RV Techs...especially from the dealers.

Thanks I believe those who live the life will put in 80 amp

Thanks for the pictures of the breakers. I checked what they did on this 2015 Montana and it looks like there are two of the smaller ones either wired in series or parallel for the three hydraulic slides. On our 2005 Montana under warranty they added a second breaker and after the first few problems never had another issue. Would you guess that if they installed the two breakers at the factory that you add the amps together to give around 80 total amps for the breaker circuit?

Thanks

I think you are asking if you already have 80 amp installed and I do not believe so. I believe one breaker is for the slides and one breaker is for the leveling system. I replaced both (which is probably overkill) and have not had a problem since.

If you look closely at the two breakers you will see the Line in goes to one side of breaker #1, from that same side there will be a jumper directly to the Line In on breaker #2. There is only one wire on the load side of #1 and that goes to the solonoid on the pump motor and runs only the hydraulic pump, but it runs everything related to hydraulics including the level up. There may be more than one wire going to the load side of breaker #2 this is the one that goes to your battery cut-off switch, this allows the hydraulics to work even when the cut-off switch is in the "OFF" position.

I am betting you have two 50 amp breakers as does my 2012 - 3402RL they are "NOT" wired in parallel to give you additional amperage capability.

My breakers are original 50 amp. As others have mentioned here I never put the slides in or out unless plugged into shore power, nor do I use the level up unless plugged in to shore power. I have never had a problem doing it this way in 3 years.

Now if you insist on changing up to an 80 amp breaker, change only the one that feeds the hydraulic pump, this will still give you 50 amp capability on the rest of the 12V system which is more than enough.

Someone else asked if there is a way to check the amperage draw on the pump, yes, if you have or know someone who has a clamp on amp meter you can easily check what the motor is drawing, if you also connect a multi-meter to the batteries you can monitor the voltage at the same time. As the voltage drops the amperage draw will increase.

Now as to the RV tech saying being plugged into shore power makes no difference, he is full of "you know what". The converter is supplying voltage to the batteries and helps in keeping the voltage up and that can easily be proven.

Since I have a amp meter and multi-meter I will check the amperage draw and voltage on my unit when operating the slides and will post my findings here.

GOOD INFO. The tech that told me that shore power would not help was from Lippert. I thought the same thing as you that it should help. Anyway going to install an 80 amp when we get to our winter gig. Had 2004 that did the same thing added a second breaker also and never happen again. ANY LINKS FOR THE NEW BREAKER THANKS
