Refrigerator trouble.

We have a 2015 Forest River Blue Ridge 3125. It has the Domestic refrigerator single door unit. The freezer part is working excellent. But the refrigerator part isnít cooling like it should. Itís just barely below room temp. I have had it plugged up for 2 days. The slider is all the way up to coldest setting and the prob is in place. And ideas?

Lots of posts on this topic. Generally, if freezer is working, fridge should be too.

Fridge should have some cold food in it from the beginning. An empty fridge wont cool (or wont cool well). If you start with cold, you're just asking the fridge to keep the food cold. You're not asking it to cool the food.

Also, fridge should not be overloaded. Fridge needs air circulation inside to work well. You may want to install a fan inside to increase this air circulation.

Hope that helps.

Having a fan to circulate the air is a big help. Something like this works well:

Also,. we usually turn ours on at least three days before we want to use it, including turning on the circulation fan. It is always down to temperature then, when we load it.

It makes me wonder: IF these fans work so well why doesn't the RV fridge manufacturers build them into the fridge units?

Depends on your camping situation. Fans use battery power. Not everybody wants another parasitic drag on their battery. Running the fan wires may/may not cause more air leakage. The fan takes up space in the fridge and may not do any good if the fan's airflow is restricted by the way the fridge is loaded.

I do not use a fan inside my Dometic fridge. I do use fan(s) in the back to increase fridge efficiency. My newest A-frame fridge comes with a fan in the back as part of the install. However, it is noisier, consumes more power, and is less efficient than the computer case fan I installed on my previous A-frame fridge.

The 2 A-frame fridge installations I have experience with did not meet Dometic installation requirements (available on Dometic web site). And the Dometic vent grills may be rain proof, but they couldn't pass wind in a hurricane. The combination of poor installation and Dometic vent grills cause the fridge heat to collect in the top of the compartment, blocking cooling of the cooling coils.

I will say the fan pushing air out the upper fridge vent makes all the difference in fridge performance. Without a fan, the fridge was very inconsistent at cooling. With a fan on the upper vent, the fridge cooled under all conditions, and cooled down much faster.

But before I installed the fan, I fixed the installation to meet Dometic requirements. I pushed insulation into the gaps on the side of the fridge and sealed the gap with furnace duct tape. I also sealed the gap at top of the fridge with Reflectix and tape. I made a curved air path to the vent from the cooling coils using Reflectix and tape. And I adjusted and added to the baffle so it met Dometic specs. Finally, I added some pipe to the chimney exhaust so that the heat would go directly to the exhaust vent.

just my experiences

The Dometic RV fridge in my 2007 Roo, had no fans.
Neither does the one in my 2016 Tracerair.
