Question Effect of no fan back there.??

Hey guys is the reason for doing this primarily to enhance the cooling efficiency of the refer?

Or to lower the ambient temperature in the coach?

Is there actually a draft of warm air coming out around the refer or through a wall or spreading along a wall or what?

Primarily to make the refrigerator more efficient. Cooling on these is by convection and they work well as long as there is a large temperature differential. As soon as it gets hot you have the dual problem of not getting the air flow over the coils and the refrigerator needing to cool more to make up for the air temp. They don't have all the fans internally and externally that move air like a home refrigerator and don't compress a gas which is more efficient for cooling to start.

All of the area around the refrigerator should be sealed from the inside of the trailer. Anytime you have a flame (furnace, water heater, refrig.) it should have an outside air inlet and exhaust to prevent carbon monoxide from entering.

So if I mount a minibox fan, say 4 1/2" dia., above the coils and pointing upward to pull air toward the vent then it will be more efficient?

Much more efficient. I had a pickup camper and thought the refrigerator was dying. I put a fan about the middle of the coils (as high as I could reach to work on it from outside) with a switch for on-off. I would turn it on around noon and off in the evening. It made it an actual refrigerator again.

For the last two seasons, I've ran a small floor fan in there tilted/pointed upward with no problems..Best of all, it really kewl its off..Plug'd in the ac outlet and it has it's own sw. KISS...know what I mean? total cost of fan, less than 10$
