Trying to keep this simple, Gas RV refrigerators are entirely different from their electric cousins. Where electric refrigerators use safe, non-flammable Freon for their refrigerant, gas (propane) RV refrigerators use compressed hydrogen gas and an ammonia-water solution. Electric refrigerators use compressors, electric motors, and cooling fans; gas refrigerators have no moving parts. IF you are still interested on how the process works you can click HERE and it will explain what each component does in the cycle. It also explains why a RV fridge needs to be level, very good article.
IF you are having issues with your unit please let me know if you have any questions on that..... Robert
The LP is used to heat the vessel that contains the ammonia solution. This can be do with LP or the AC heating element for the fridge.
