Ammonia refrigerators need to be level to work properly no matter what HEAT source you use (120VAC, 12VDC or propane).
Operating it when out of level won't hurt it. It just won't work very efficiently. And f it is too far off level it just won't work at all.
HEAT? Are any of you confused yet?
Yes HEAT is what makes an Ammonia fridge
work. There are three heating elements in typical RV fridge
. One is 12v. one is 110 and one is LP.
Guess you could do a search on Ammonia refridgeration to get a picture on how it works?
BTW..... this is a bit off topic so if anyone wants to discuss this further a new thread she be started.
