Agreed! Absorption refrigerators have a very small tolerance for being out of level. Operating off level for too long can damage it. However, I don't know if that is the issue.

Does it work on propane (also requires leveling)? Do you see lights on the eyebrow board? When you open the door, does the light turn on? I had one in our prior R-Pod 179 where the electronics went out. I ended up replacing it with an AC/DC only compressor refrigerator which was not as finicky when it comes to leveling. That was at the cost of being able to boondock for longer than a day or two. However, it did keep things colder and frozen things frozen much more reliably than the absorption refrigerator did.
