Diometic refrigerator problem

[Jimongee]

I have a 2006 Montana 5th wheel. I just took it out of storage. When I attempted to get the Dometic refrigerator going I found that the upper freezer would quickly cool to 21F. But the lower refrigerator compartment had absolutely no cooling. I confirmed the gas heater was fully functioning. It presents the same problem on AC or gas. The RV is totally level. The condenser fins are totally free of debris. I'm stumped. If you can help I appreciate it. We are expecting to depart on a cross-country 3 month trip as soon as I resolve this problem. Thank you

It takes the refrigerator part longer to "get up to speed" than the freezer.

Thanks but I monitored it for 6 hours and the lower compartment still had no cooling. Also this model does not have a recirculating fan in the freezer section. Instead it has a coil in the freezer and a separate fin type device in the refrigerator lower section.
