Refrigerator Fan Upgrade

I've been reading about the issues with LPG Refrigerators not cooling in hot weather, catching fire etc. I've not had a problem in 25 years but I saw a Montana at a campground with a house fan blowing on the refrigerator vent and thought I should see whats out there.


I found this https://www.amazon.com/gp/product/B0...QROUNPT13&th=1


What's your thoughts?

That's the idea. I added fans and thermistor to mine a couple years ago. They definitely help keep the fins cooler. The side vent systems (because they are in a slide) just don't move enough air through. There are several YouTube videos on the subject.

I bought two fans to put on the inside of the fridge. The temperature swings was a bit much for my liking. After I installed one inside the fridge temp is consistently around 36⁰F with the fridge set on #4.
I'm going to install the other fan on the top outside vent to draw hot air out.
Looking through the wiring schematic for the fridge, the factory installed outside fans don't come on until its 130⁰F.
I believe that's too warm. Hopefully after I install this additional fan I will have hard ice cream lol

It's sad that that's really the issue, isn't it? I find that the ice cream stays much more firm on the bottom shelf of the freezer

I want to start with the vent fan and see what kind of difference it makes. My understanding is it's mounted to the upper vent blowing out. Is that correct?

That's the way I did it. Most YouTube's I found did it that way as well. It makes sense to me since the issue seems that more heat gathers in the space above the fridge. The fans move that out and help draw more air from the bottom and across/through the fins for better cooling.

If you go to the ARP site, there are pictures how they suggest mounting the fans, which you can purchase on Amazon separately if you donít want to install an ARP device. I have the ARP device and it has made a huge difference. The fridge is working great, and I havenít needed to replace the cooling unit since the second one was installed in 2015, and with the two extra fans, the temps in the fridge and freezer are very good. Itís 100 degrees outside here as I type this, and the freezer is at 13 degrees and the fridge is 40, which works for us. www.arprv.com

Not for nothing, that amazon price of $88 for two muffin fans seems a little ridiculous. I bought this for $14 and hooked it together myself https://www.amazon.com/gp/product/B08BLTW8RX/

That all good and I'm a fan "no put intended" of saving money but for $88 I get an auto fan speed controller!

Our Dometic RV refrigerator was not properly cooling properly, we did a few things to improve it. 1.) installed 2 additional cooling fans. 2.) made sure we had the 1" gap behind the fridge. 3.) insulated the refrigerator cabinet. We live in AZ and can now pull our refrigerator down in 24 hours in the summer in our covered storage lot. Numbers 1 & 2 shared above are based upon the refrigerator manuals. #3 was the idea of our RV service company and seems to have helped as well.

I have had good results with ARP fans and device for my RV reefer.

Did you connect them to the OEM fans? You need some kind of controller/thermistor so the fans come on when needed.
