We are in Zion with 103 degree temps. My fridge is having a hard time keeping cool. Electric or gas doesn't seem to make a difference. Everything appears to be working fine: level, nice blue flame on gas, no birds nests in vent cap, shading the fridge side with awning, etc. Fridge has always worked perfectly. Two fold question. Can heat affect it this much? (Lucky to keep it at 40 over night) and, any tips for helping it along in the heat? It's a Dometic New Dimensions. I'd give you the model number but I don't want to open the door!
