Dometic and Norcold RV Refrigeration Rebuilding Process

Thank you for considering a NuCold cooling unit
Re-Manufactured Cooling Units for Dometic and Norcold RV Refrigerators
All Units include a two-year warranty

This is a general overview of the process by which we build our cooling units.  If  this is the first time you have ever had trouble with an ammonia cooling system, you may find this page interesting.  We will show you the parts that typically go wrong with an ammonia cooling unit and what is unique about the way we repair them at Nucold Refrigeration.  Just follow the illustration below and it will refer to thumbnail photos in the left margin.

"H"  This is a picture of a Norcold cooling unit that has just had a new evaporator welded in. Now it is ready to be flushed out for contaminants and sent to the charging room.  One reason we flush the cooling unit is for contaminants that can get in the tubing during the various stages of assembly, but another and very important reason is to check the flow of certain lines to make sure there are no restrictions.  Very often we will find a cooling unit that has had a line welded shut or just partially welded shut at the factory.  Sometimes this will stop the cooling all together but more often it just makes the cooling unit act sluggish.
