I bought two refrigerators last year that used propane as the refrigerant. Both failed with a week of use but did not explode.

Maybe we need to bring back the old non electric ammonia type that used a very small natural gas flame to make it work.

Propane is a perfect drop-in replacement for R-12, the old refrigerator coolant( far as function is concerned).
But obviously propane is flammable, not good in an electrical setting.

I too just bought a small dorm sized refrigerator,. The Refrigerant? R-600, isobutane. Very flammable.
