There are a few RV refrigerators that run off 12v.
They have a 12v heating element.
To the OP... do you know for sure if yours is a three way model? (12v-110v-propane)
Also, if you do not have a three way and you have your refrigerator on 'auto', the propane has to be turned on for it to light/run once the shore power is removed and the auto select has happened. As mentioned it also has to have 12v for the control circuits to work. (battery disconnect has to be 'on' if equipped)
