How to mod fridge venting

I have poor venting on my fridge, I see that they placed a baffle to force the air over the condenser but leaves very little opening for the air to escape out of the plastic cover. I added another fan to the existing fan but when temps rise into the 80's the fans never shut off. I remove the cover and that helps and I also have removed the top baffle and that helps even more, but it is idiotic to have to do that when camping and looks hideous. Was thinking of adding a couple small fans to the plastic outside cover itself, but there is so little room. Also there is a cabinet above the fridge inside, almost inclined to make a door in which the fridge can vent into the cabinet/camper.

Thoughts?

Refrigerator Ventilation for Slide Units

Here is a post I submitted with multiple pictures, hope this helps. Also, there is a link with diagrams and information about ventilation and removing dead air space.

Do not vent into the camper! When the fridge is run on propane you could get gasses in the camper. These units are supposed to be sealed from the interior living space. As far as better air flow on the condenser I had a unit in my previous camper configured the same as your's. I put two fans on the inside of the vent cover blowing out and it worked very well. Sorry I have no pictures and no longer have that unit. By the way I wired the power to the fans thru the thermal switch on the condenser so they only ran when needed.

Good point, didn't think about the issue when on propane!

I like the idea of the fans behind the condenser, were you able to install the fans from that access panel and removing the baffles? It looks like you had more room between condenser and the top then I do.

My fridge is not on a slide, wish they just roof vented it..oh wait that might cost 3 cents more Grrrr

I added two computer case fans to my fridge cabinet just below the top vent opening. I did this mainly to rid myself of the racket that the original equipment fan made when it ran. It was very annoying to me. I also dropped the luan piece of wood out of the vent opening because I felt it was a poor design that limited air flow. The computer case fans that I put in there are super quiet (can not hear them run inside my Cedar Creek) and move a tremendous amount of air. I have one fan wired to the factory thermistor on the cooling coil and the other fan on a manual switch that I have never had to use. Even in Arizona heat.

Where did you get the power for the cooling fans? I see that many of the fans are USB so I suspect you are getting 12v and adapting to USB.

I used two old fans from computer cases. Just cut the wires, spliced them and ran them through a Micro switch I mounted in the wall beside the reefer and a 12 volt supply line to the control board,

If you have a Dometic 2652, there's probably a white connector like I've circled in the pic below. The red wire is +12VDC, the white wire is -12VDC.

I've installed two fans. The red/green wires going to the right go to two switches I mounted under my bathroom sink that allow me to turn them on/off without having to open the outside grill for the fridge. The red/black wires going through the black connectors go to the actual fans.

My fans are 3 speeds; that black wire hanging down with the small black box on the end, just to the right of the red arrow, has a small switch in it for changing the fan speed. 7 bucks a pop. I do have open the grille to get to the speed switches, although I could probably just let them hang out of one of the holes, like the drain hose does! I had hoped I could extend the wiring, but it's just too darned small to mess with.

Do the fans run 24/7 when you are camping?

If no how are they switched on & off?
