A RV cooling unit is NOT regulated above the lower section, hence the freezer gets between 0 and 10 degrees regardless of the Temp setting on the refer. The freezer will get COLD faster. You MUST wait 24 hours for a test of the lower section. Air MUST circulate in the lower section. That means you must have at least 1 inch free space at the back wall of the lower section. This allows convection air to flow quicker from the bottom of the refer up and thru the evap fins to remove the heat. The fins will be 10 degrees colder than the temp of items in the refer. If the fins are 26 degrees, then the items will be 36 degrees. A BAD(blocked) cooling unit will still get the freezer extremely cold. That is why novice RV'ers that buy used units and do not understand this get ripped off when they see the freezer is real cold and assume the refer is working to spec, but then find out the refer is BAD. Give it overnight and see what the temps are in the morning. Doug
