Warm air from the coils rises, so fans to exhaust up.

So I have done everything that I know what to do but I still have a cold freezer (-5) and a warm fridge (40-60). I didn't have any fans behind the fridge, so I added two exhaust fans in the stack and two under the fins. I changed out the thermistor and the control board, but don't know what to do next. Any ideas?

My $.02....

The roof vent exhaust fans and the fans below coils (pull/push air) and a refer condenser fan is typically all that is needed to maximize cooling on a properly INSTALLED and running ammonia refer.

Check to see if the refer was PROPERLY installed (many are NOT) based on manufacturer's install instructions for your model (easily found online or included in your manuals when purchased . Ex. Too much gap between refer and rear wall allows hot air to gather and will not allow refer to cool properly.

You need to consider the ambient temps and temps inside RV temps when gauging expectations. If you are checking today, or the next few days......it's **** hot in central/southern AZ....several degrees over 100F today!

Is your RV in shade or sun?
If sun, does sun hit refer side?

Also, pre cool your items going into the fridge if you can. Cardboard, paper etc stores heat so keep it out of the fridge.
I use compressed air to blow up the chimney. If the coils have dirt on them they will not cool properly.

I'm sorry to tell you this but, that style of Dometic fridge SUCKS. My brother has one and has the same problem. My 29-year-old Norcold works a lot better than his brand new Dometic. I don't think you are going to be able to fix it.

I'm sorry.
