Thank you for considering an RV Fridge House cooling unit
Re-Manufactured Cooling Units for Dometic and Norcold RV Refrigerators
All Units include a three-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 RV Fridge House. Just follow the illustration below and it will refer to
thumbnail photos in the left margin.
Our first step is bending all the pipe that will make up the replacement
evaporator. We designed all our evaporators (both Norcold and
Dometic) as one piece units with the hydrogen return tube inside the
larger 7/8" pipe. You can see it coming out the top of the larger pipe
in the photo. Then we bend the small lines that carry the liquid ammonia
from the condenser to the top of the evaporator. Then the brackets are cut,
which will pull the evaporator tight against the refrigerator fins.
