Just bought a 2nd hand camper with a fan fitted to a filtered air vent on the drawbar box for the fridge. When do people run the fan? Is it every ime the box is closed, only in very hot weather, or only when driving on dusty roads?
Thanks

Isn't the reason the fans are there, to change the air around the fridge so it doesn't stew in it's own heat which it is trying to dissipate? No good having heat from any source heating the fridge and it's condensor, so it works the hardest all the time and use far more battery than required.
As long as the fan running uses less AH than the AH used during the less run times it provides for the fridge then the battery is in front.
The use of a fan may even allow the fridge to freeze if it is cool enough outside in the enclosure.
I use a computer fan running full time with appropriate ducting to provide cool air to the fridge and it's condensor while it is in a vehicle. Vehicles get hot inside like fridge boxes do.
Who
places their house fridge in front of the gas heater? Same effect as a box in the sun.

the fan is there for two reaons
1/ so the fridge is nor recycling it own cooling air
2/ to keep temps down from outside sources of heat.
both with the same goal .... keeping temperature down in and around the fridge.
cheers
