Landing gear stuck

[NMex445]

I’m stuck still hitched up to my ‘20 Montana. I have the 6 jack LevelUp system.

Checked my twin batteries and they are fine.

When i try to use manual mode, the jacks click and then stop.

The ground underneath my unit is rough and the front to back is showing -0.0 and side slightly right.

I called Lippert and understand the front-to-back needs to be positive +.01 or more.

I had it nose up .01 and the gears still didnt extend the jacks.

Autolevel button leads to long delay and “jack time out”
Right left simultaneously leads to “feature disabled.”

I zero calibrated auccessfully, but my nose positive +.01 went to 0.0 as a result.

Power flowing to pump but jacks might be stopping due to a circuit breaker.

My two back slideouts failed to slide out as well, at the same time as the jacks.

Appreciate the help. I am trapped and would rather not have to manually extend the jacks.

hello NMex45, Sounds like you have low hydraulic fluid in your reservoir, or possibly a bad pump??? Might be a good place to start. It would help to know the model of your rig:}

Sounds like a circuit breaker. Can you hear the pump run at all?

Download the Lippert NOW app from Google play store. Lots of good info, manuals, TSB, troubleshooting etc.
Lippert also has excellent help desk support.

In their troubleshooting steps, they talk about jumpering around the red self resetting circuit breakers on the wall behind the batteries, then run it.
If it works the 50A red self-resetting circuit breaker is weak.
The Lippert TSB recommends putting the hydraulic system on its own 80A circuit breaker.

Here's some links that talk about it.

I’m tending to agree it’s a bad pump.
Thanks so much.

Before you replace the pump or pump motor, be sure there is power going to the reversing switch. If the auto reset breaker that feeds 12 volt power to the switch has failed, the pump will not work, and you will not have power inside the rig on the 12 volt side if the shore power is disconnected. If that is the case, the auto reset breaker will need to be replaced, and should be replaced with an 80 amp breaker per Lippert. If the breaker checks out, then there is a procedure for diagnosing the hydraulic pump and switch.

If the breaker is bad, these are photos of our breaker install behind where the batteries are, a photo of an 80 amp breaker and one of what the 50 amp breaker looks like without the red plastic insulator. https://manuals.heartlandowners.org/...ippert0058.pdf

The pump is $900 or more. The 50 amp self resetting circuit breaker is $5. I would be very sure the pump is bad before I would replace it.

If, by chance it is a bad motor, you can have it rebuilt for less than a third of the cost of a new one. https://www.montanaowners.com/forums...ad.php?t=82928
