I've had good results adding a small muffin fan to the exhaust vent on my fridge. I always planned to make it permanent but have yet to find the time. For now I hang it on the vent with wire formed "s" hooks, blowing out. I clip the wire directly to the battery. It's crude but it works well. The fans are easy to find. Old PC's typically have at least one. Of course you want one that runs on 12 Vdc. Good luck, Raz

Those typically go on the inside of the fridge at the bottom to get a little circulation going to prevent hot and cold spots inside. I think James and Raz are talking about a fan that blows on or through the outside condensor coils. They are usually 12v. Sometimes solar. On bigger roof vented Rv fridges they sometimes go in the roof vent cowling. I have seen one that has a roof panel and a small fan that snaps to the vent.

I think it's worth looking at how the vents are constructed first before going after fans. The venting in my U-haul was awful and although it had a lower and upper vent, it was mostly blowing past the upper and venting between the trailer walls into the trailer! I made a guide for the top out of 3" metal duct tape beginning along the back upper edge of the fridge and going up at 45 degrees to the top edge of the upper vent This helps to guide the hot air out of the upper vent, keeping it out of the trailer and preventing it from heating up the fridge box. I also added some Reflectix insulation on top of that. It's working so much better!


Regards,

Matt

The round fan they show is available with a solar panel, too

One of the URLs I have in my database for a future mod, is a fantastic thread about refrigerator fans on the CasitaForum. For those that are members there, check out this topic: Refrigerator Fan Modifications
