We put in a 12 volt compressor fridge mid summer and it has worked just fine. We are leaving Friday for a trip to California over Thanksgiving so i turned on the fridge this morning. I just checked the temp in the freezer after about 8 hours of being turned on and it is showing about 30 degrees. Could that be because the interior of the trailer is also in the low 30's? The trailer is under some trees beside our house in Salt Lake City and it is about 35 degrees outside right now. I am guessing that since the fridge does not have to work to cool down the fridge department it is also not cooling down the freezer department. Anyone have any thoughts on this?
