Fridge Cooling Fans
My TT is stored in Arizona and when I go to get it in the summer it can be hotter than hell inside. Last summer I turned the fridge on and even after 24 hours it was struggling to cool down to a usable level. After doing a bit of research it seems the fridge relies on the airflow from ambient air. Hmmm... we have lots of days with zero wind, not great.
So here is the mod that I made. I don't know yet if it helps but I figured it can't hurt and it is almost completely silent.
I took three 120mm PC case fans and attached them to an existing wooden baton so that they would blow air onto the fridge coils, pulling it in from outside. There is an on/off switch, accessible by removing the cover, but I leave it on all of the time and use the battery disconnect in the basement to turn them off while in storage.
Here is the design. It's just three identical 3D printed parts:
These are the parts, printed in Ninjatek Armadillo.
I found I could take 12V DC from this convenient "choc-block".
I connected the switch to a four-way fan power controller, obtained cheaply from Amazon or ebay. Each fan is connected to this, then through the switch to the 12V supply.
Here is the final install. Switch is mounted to the hole on the left-most fan holder. I believe I tided up the wiring with cable ties after taking this so there is no movement of the wires while bumping and bouncing down the road. Image is rotated but I can't figure out how to remove it from the post so I can attach it the right-way up.
Here is the STL for the fan holder: https://www.dropbox.com/s/67g6moj4oa...acket.stl?dl=1

Nice job on the fan install. Any extra flow helps.
Any way you can precool using a portable generator?
Also, not sure on your layout but make sure it is insulated above the refrigerator. There have been situations from the factory where there is not enough insulation allowing pockets of hot air to form on top or along the sides.Last edited by SilentService; 04-09-2023 at 08:10 PM.

I did something similar, but have them blowing out at the top rather than in at the bottom.
If you want it a little more automated, replace the switch with this..

In some installations there is a lot of room between the cooling fins and the wall of the camper behind the fridge. The air can flow up through this space without passing through the cooling fins. I have seen where some people have gotten good results by putting a baffle between the cooling fins and the back wall to force the air to pass over the fins.
