Exterior cooling fan for refridgerator

What fan has anyone installed and how was it positioned to cool the fins for the refrigerator. It appears a fan of adequate size would block the AC/DC controls. I have a 2014 A122S. A picture of you fan in the compartment would be great.

Buy a 120mm ball bearing computer fan.

Thanks TURBS, I see you have a fifth wheel and I have a small A Frame. I was hoping to see the compartment of an A Frame with fan installed. Thank you for the site however to order fans.

Can't help you on the A-frame sorry.

Good luck and pics of your project will help others!

Mine has 2 fans installed from the factory they are located at the top of the coil to help draw out the heat and they work good. Mine are cycled on by temperature so they are always cycling on and off. I also put a dual fan on the coil on the inside to keep the temp the same throughout the big fridg. works excellent. 33 deg. cold ones

Installed a solar powered one in an older MH I had. Worked great.

It's a mod I haven't gotten around to. As is, I get adequate cooling, freezing everything inside after 24 hours if I turn up the gas or AC to max cool. So it's not an urgent mod for me.

If I were going to do the mod, first I would try to put some baffles in to get a natural chimney draft on the external cooling coils. You want the the natural draft to go in the bottom grill across the coils and out the top grill. I probably need to screen the inside of the grills to prevent insects getting in.

A 12 volt, 120mm computer fan (like Turbs suggested) would be the next step. I'm not at all sure the gains would be significant if a decent chimney was in place. If I did put a fan in, I would want to have it easily removable so as not to block air flow when not in use - we do a lot of camping with no hook-ups. I would install the fan near the bottom of the fridge to blow air up the chimney. This would not interfere with the fridge controls - my switches are all in the top half of the compartment. I would also install a switch to turn the fan on or off to preserve battery when not needed.

just my thoughts

Don't have a picture for you but would suggest when you purchase one look for the highest CFM and lowest DBA you can find. I like this one but there are higher CFM's at a lower price if you look.

I did this mod a few years back

when I had an older regular popup, and I used an old computer fan, mounting it right inside of the outside air vent. It really improved the cooling.

My A122 of year 2012 works very well when running the frig on shore power electric, so I don't see a need for the mod again.

I was just about to write the same thing.


McPhee, you should consider installing a baffle in addition to or even instead of a fan. RV fridges use convection to keep the air moving over the coils and the fridge compartments on full height campers are designed to make use of this. Our folding campers cannot provide the proper air path. Using a baffle that forces the airflow from the bottom of the compartment over the fins at top greatly increases the cooling capacity of the fridge.

I used a small amount of Reflectix cut into a shape that fit into the compartment right up to the fins and flue. It is an easy mod. The material is made as radiant barrier insulation for attics, so it is durable in the heat and has Class A/Class 1 fire rating.
