You probably have a blockage in the system. I had the same issues many years ago. If you’re handy with tools you could order a new cooling unit and change it out ( YouTube it) or you might find a replacement on Craig’s list or Facebook. The change out is relatively easy, but buying used could be problematic. Good luck. Re: Norcold Model 611 Fridge problem You have an old unit, 15 years is a long time. check for any blockage up the flu and barring that, you're gonna have to replace the unit or get a cooling unit upgrade from JR Refrigeration in Indiana. Look him up on facebook/utube, I used his services on a previous motorhome, worked great. Good luck
