Old Sunon fan in top pic was replaced by 2 new Gelid thermo controlled fans in the bottom pic. Silence is golden! This was done back in the spring and has worked great! The 2 new fans move more air and draw less current than the noisy original.
Amazing any of these fans work at all, they must recirc the same air over and over without any baffles or duct.
Whats the access to the fans, upper door? Mine and others it's pull the 200# box. (4 door 1350)

I'm not sure I follow you!
With the 8 cu.ft. Dometic, the fans are actually in a duct, formed by the space between the back of the fridge and the trailer outer wall! The fans do not simply recirculate the same air over and over! There are 2 large vent openings (each one over 1 sq. ft) in the side of the trailer; one at the top and a lower one near the bottom... The air flow is "in" the bottom and "out" the top! There is no need to pull out the fridge, as there is lots of access with the vent cover removed!

And we all know heat rises anyway !

Mine has a vent in the bottom then a duct work that goes to the roof.
My fans are mounted within the duct work so as previous poster said it draws in cool air in the bottom and blows hot air out the roof vent.

You sir are not. When you corrected me as to open the top access and change the fans, it prompted me to check your source. Not sure if this is your first RV but I've had motorhomes for 15 years. I've never had two side vents on any of them. Two vents normally fitted in slideouts as in the 29' Crusader. I'd venture to guess maybe 10% or less of RV's have two access covers for fridge. Thats why I asked you, it sounded too easy.

With the 12.5 cu. ft. boxes the fans are mounted on the back, below the finned tubed "condenser". Remove the roof cover one cannot reach down past the sharp finned tubes, you must pull the fridge to access them.

Research this Forum for fans in refridges and you'll see lots of examples of installations of free flowing fans at top of fridges and blowing from the bottom, all without ductwork.

Lastly the fans in this design are in a "Plenum" between the box and outside wall, not a "duct". They do recirculate because they aren't in a duct and the condenser offers resistance to flow and creates backpressure. Of course hot air rises, thats why Dometic and Norcold added fans, they were around for 50 years without fans.

Before you drop the hammer, do some homework. Thanks for your input.

Sorry if I offended you, Vince. I meant no offense.
