If your frig is vented on the roof then "normally" there is not a fan but if it's vented to the side of the coach, you should have a fan. We are presently waiting on a new frig because ours broke..lol...due to not having a fan to cool it off. Yes, ours is vented from the side of the camper. New frig should be here tomorrow and installed Monday and it's also a Dometic. That is what Dometic told us via dealer doing warranty work.
