First of all there is no compressor in your Norcold 3 way fridge. I don’t know what you are hearing but its not a compressor. It has gas or a 12 volt DC heater or a 120 volt AC heater.

You have now learned that you cannot operate it parked off level on a hill. The refrigerator operates by boiling an ammonia/ water solution. The vapors go up to the freezer compartment as a gas and condense and picks up heat and the liquid flows back down to the bottom to be heated again to epeat the cycle. If operated off level some of the ammonia will not be able to run back down and the heat creates solid crystals that clog the tubes. Once the crystals form they will not redissolve and so the tubes become clogged forever.
If that is what has happened to you then the only solution is to replace the refrigerator or to have someone replace the whole cooling unit in your refrigerator box.

There is no problem driving up and down hills because the motorhome moving keeps the liquid in the refrigerator from getting trapped. When you are parked be sure to be somewhat level. There is usually a small round level with a bubble that comes with the new refrigerator. The bubble shows in the center when its level. You should try to keep at least half of the bubble within the lines at the center.

If I park on a hill (such as going into a restaurant or a store) I always check the level and if I am slanted too much I shut off the refrigerator until I return and begin to drive.

There are several sites on the Internet that explain this in detail. Here is the first one I found in a search: http://www.truckcamperadventure.com/2015/02/rv-refrigerators-how-level-should-they/
