Self Leveling System Not Working? Here's what you can do...

Many RVs have self-leveling systems these days. It is a great feature. You get to your spot, press a button, and like magic your RV is level. Many RVers will get to a location, set the levelers, and assume the system is accurate. That is what my wife and I did until one day, after leveling our rig, we noticed it looked like it was leaning to one side. At first we thought it was an optical illusion. After it bugged us enough, we pulled our bubble level out. Sure enough, it was quite off.
Why Leveling the Rig is Important
There are obvious reasons you should want a level rig. You probably like things to stay on counters. Many people don’t like sleeping on a slope. There are some mechanical reasons, as well. RV refrigerators run on gravity, and running them stationary, on an extreme slope, can damage the unit. It is also helpful to have a level rig if you want to properly read your black and grey tank levels.
What Caused the Malfunction
My parents happened to be staying at the same RV park we were staying at for a bit. My dad noticed the rig did not look level. I asked him if I should take the RV to a repair place, but he swore up and down that we could adjust it.
In order to prove him wrong, I took out the manual for the RV and browsed through it. Turns out, there is an adjustment. Our circuit board contains an electronic level that can be adjusted. Over time, with the vibration on the road, the electronic level was thrown off slightly. It needed to be recalibrated.

How We Fixed It
Fixing this problem was easier than I thought. It required a socket wrench and a screwdriver. The first step was to find the circuit board for the leveling system. Your manual should have instructions on how your board should be adjusted. We used a bubble level inside our RV and manually leveled the rig.
After the rig was level, we revisited the system’s circuit board and adjusted the leveling chip until it read level. The chip uses lights to indicate proper adjustments. I tested the adjustments by pulling up the leveling jacks and trying the auto level feature. The leveling system was on par.
If you have a HWH leveling system, your circuit board will look like this. The leveling card you will adjust from the outside of the box is the card on the bottom.

Conclusion
Just because a leveling system says auto level doesn’t mean it’s maintenance free. To avoid this issue, I have decided to keep a bubble level in the rig and check to see that the fridge area is level after pressing the level button. If the system is ever off again, I will know where to look first and if that is the case, the adjustment process is easy. I hope passing this information helps someone else with leveling issues.
