I replaced my cooling unit inside the trailer. I removed the table and put the refrigerator on a portable 'workbench'. It is not too bad a job. It took about 4 hours. The hardest part was to cut out the old cooling unit out around the freezer area. I bought ours from RV Icebox, it lasted about two years and quit. I called them after it quit and it appears that they are now out of business.
So, I bought a new refrigerator. To get the old one out and the new one in I removed a window and passed it through. I think it is worth the little extra money to replace the whole thing. The new refrigerator now has a auto start rather than a Piezo igniter so I had to run a new 12vdc wire to the refrigerator.
