Yes it works. Moves the air in the frig , helping cool faster. This link is to a project page that friends have followed. Hope this is okay to post.

sorry if I'm not to do it this way.

I've heard of a mod with installing a computer fan in your refrigerator and its suppost to either cool it faster or make it cooler? Has anyone heard of this trick? Does it work?
Yes it works, I had two of them on our pup which had the small 1.2 cu ft fridge or whatever it was. Before the fans the coldest it would go on an 85 degree day was maybe 45 or so, after it would start freezing the stuff in the back. I am going to put some in our hybrid but the way it is, with the 6.0 fridge I either will have to pull the fridge out from the inside or remove the roof vent to get the fans in. That's a spring project.

Old_Geezer,
Do you really need that fan?
I picked my Hybrid in June and it did spectacularly during the summer.
The Hybrid have the advantage of a tall chimney which helps tremendously with cooling.
We had plenty of ice in the freezer and cold in the fridge on hot days.

Lou, do you happen to know my wife? lol, sure sounds like it. She will ask the same question. Most likely I do not need it, but unfortunately I can not leave nothing alone. especially anything with wires or electronics. I have a bad case of terminal moditits.
OK, I opened up the camper today and tried to test a few things with the refrigerator.
1) I checked the temp in the fridge before starting - 52 degrees
2) I turned on the fridge to A/C for 2 hours - 52 (no change) 🙁 I checked the outlet and fuses to make sure there was power. Any thoughts?
3) I then changed it to propane for 2 hours - dropped to 32.2 🙂
4) I've now change it back to A/C for overnight and see what happens after 12 hours? :-
After I make sure that the A/C, D/C and propane work properly, I'm going to install 2 fans with a switch. I assuming on the exterior, upper baffles, blowing out, to remove the heat build up?
What does anyone know about adding a thermodisc?

There seem to be two fridge fan mods I've read about, external and internal. The internal fan will help stir up the air inside the fridge and avoid warmer/cooler pockets and get the warm air onto the cooling fins, yielding more even temps and faster cooling of items within the fridge. The external fan blows on the fins in the external fridge compartment and helps the system shed heat by keeping air flowing past the coils, and I would imagine make the cooling system a lot more efficient, especially on hotter days.
I haven't attempted either mod myself, but i was starting to collect parts to do the external fan mod. With the new HTT, I may not need to do that any longer, or I'll need to modify my design. I was going to use a quiet 1200rpm, 120mm fan sitting between the upper and lower access door.
Joe, I did the fans mod in the Seapine and it made the frig work so much better to the point where we used the fan all the time. It made for much faster cooling and less propane/electric use.
I used a single 12 V fan attached to the backside of the vent grill at the top of the frig stack. ran the wires down to the 12v ones on the fridge. 30 minutes and done. Worked very well.
I assume I will do the same mod on the Flagstaff HW when I pick it up this weekend as that has a much larger frig.

I ran the fridge for 3 days in all 3 modes. Worked great. It takes forever for the AC and DC to cool it down but works well once there.
I worked on the fan mod in the rain over this past weekend. The fans and air deflector plate are installed, switch and wiring still to be completed.
upper access panel removed. pre-fan mod work

I installed a thin piece of wood to force the air across the back of the fridge and over the baffles (metal would work well too)

Two fans attached to the remaining aluminum L channel leftover from fixing my bunkend cross bar.

Switch and wiring will be completed soon. I hope.
