Updated fridge recirculating fan

A couple of years ago I found a thread on the forum here about the cooling issues with the absorption refrigerators. I knew about that from my family RV days growing up in the 1970's. Ice would form on the cooling fins from the condensation from the opening of the refrigerator door. That ice would inhibit the heat transfer from the internal air convection process.
One of the ways to deal with that condensation and ice formation is to install a cooling/recirculation fan from one of the vendors that runs on batteries or install a 12v one that blows on the cooling fins.
So I found a solution and posted it here.

http://www.forestriverforums.com/for...ate-12632.html

One of the hard drive cooling fans eventually croaked in 2013 so I installed a computer case fan the same way. Alligator clips on the back connected to the Ground wire for the fan and the Positive connected to the hot wire on the fridge light. You can check which wire is always hot or powered on the light with a volt meter or a test light if yours differs from mine.

Relatively quick and cheap.

Hope this helps.

Very nice, good job with that. Never would have thought to use the lights power.

I had mine wired that way. But I kept blowing the 3amp fuse in my fridge circuit board. Finally had to run the hot wire through the port for the temp probe and catch an outside 12volt source. Just a heads up if it starts to give you problems.

Is that a 80mm or 120mm fan? Thinking about installing one in fridge for internal circulation and one in external cavity for venting. Maybe a 80mm for the inside and a 120mm for the outside.

120mm computer case fan

Captain -
I checked and the fan is 120mm.
I'm not sure if it is a ball bearing or a sleeve bearing fan, packaging is long gone. So far there no noise to notify me of impending failure.

Hope this helps you.

That is a very clean solution!

cfiowa, Do the Fridge-fix lights stay on while the door is closed? Neat product!

Just shopping on Amazon and found this....https://www.amazon.com/Cooler-Master...=dradisplay-20

May not be as bright or neat as the Fridge-fix, but a lot cheaper!

Our next camping trip is at the end of July, going to make/buy something before then.
