I have a question about cooling a refrigerator. I am in the process of installing a Norcold 323 3-way fridge in my 1978 Rockwood popup. The camper originally had an icebox (long gone before I got the camper) and was replaced with a cube-type dorm fridge. I decided I wanted an absorption fridge which could be used even without an electric hookup (since my wife and I don't own a generator...yet). My dad and I boxed in the former icebox opening so that there is practically no dead airspace inside to the sides, top and bottom, and put in a baffle at the rear to force air to go up and past the fins. My dad says I should install a fan in the upper vent to suck the hot air up and out more efficiently. Has anyone here successfully used a computer fan or similar to do this with a side-vent fridge? And did you install a thermostat (and if so, what one)? Looking at the price of ones purpose-made for cooling RV refrigerators, they are EXPENSIVE, especially since my hours have been temporarily cut back at work (I could buy more than a full tank of gas for my tow vehicle, even two tanks of gas, for what a purpose-made RV fridge vent fan costs!).
