Fridge cooling: coils or fins?
I'm making an extended trip into a hot area, and often my Dometic fridge does not cool adequately. It has no fans at the back to help cooling, and so I'm adding 4 thermostat controlled fans, as well a...

Hi,
I got more benefit from dual fans inside the fridge than from cooling the outside stack. I chose to use a vent mount just under the rain cap. I made a mask to restrict help flow in the winter time. The twin computer fans are thermostatically controlled.
I do have the ARP unit to help prevent overheating. It has been a great relief to me.
Fans inside and outside will help dramatically. As to how many fans on the outside, you only need 2 fans max blowing UP. Have them BELOW the condenser fins blowing up. As Chris stated, you need to make sure (OEM's rarely get this correct) the space between the fins and the sidewall is blocked off to force all the cool air thru the fins. Now, if refer in a slide room, you need another modification. Add 1 fan at the top blowing OUT the upper access door. to help remove the HOT air that has just passed the Condensor fins. THIS fan is critical even of you have the fans below the condenser. Most OEM's do not install this top fan on slide out installs. So, if you already have fans on a slide install, add this extra fan. Now, to fans inside the refer. The refer operates inside by convection air flowing upward along the back wall up thru the Evap fins (which removes the heat) and over and down in a continuous circle cycle. With Plastic tubs and Freezer type bags being used now, people OVERPACK the bottom of the refer and restrict this air flow and rear 1 inch space needed. Having that rear 1 inch space will make the refer cool much better. But, adding the inside fans will help tremendously because people will always block that cycle of air. Doug
