The cooling fans on the back side of the fridge and not based on air temperature, they are based on the temperature of the fins they are in contact with. The themostat on the fins is a contact type, there is a 12V lead and two leads, one for each fan. When the temp reaches approx 130 degrees on the fin, the fans come on, pull air in the lower vent and out the top vent.

I have replaced both fans and one themostat.

If anyone needs the complete kit, I found the part numbers and will look them up. The assembly is called Dometic Power Vent Assembly. There is one with one fan, and the one we need is for two fans.
