A couple years back the Norcold in my 97 coach decided it was time to stop working. Of course we were in the middle of a monthlong trip.
Anyway after going back and forth about a new frig. or replace the cooling unit. I decided to replace the cooling unit as a DIY project.
I decided that way for a couple reasons, one I am not a very good carpenter and the replacement frig. would not look like it belonged. Get the new frig. in my unit would not be an easy task
I ended up going with replacing the cooling unit from JC Refrigeration

As I am always plugged in and never boondock I decided to go with the 120v only unit. It was a very easy DIY project for the DW and I. JC Refrigeration is really a customer service business. From the how to instructions to answering questions they are number one.
It took in total maybe 2 hours +/- to finish. Once in the unit has kept ice cream frozen and the adult beverage cold all on setting 5
Good Luck
