Problem with a 6 year old Dometic frig

Friend of mine has a class C with a Dometic frig not working. We did some investigating yesterday, and found the following:

Propane flame works when in that mode

Electric heat works when in that mode

Frig temperature doesn't change in either mode and stays constantly at 51

My conclusion is the frig is broke and needs a new cooling unit, or am I missing something?

BTW, my suggestion to him was to install a residential unit instead.
