This is <strong>Dometic</strong>’s <strong>Manual</strong> Refrigeration Diagnosis and Troubleshooting program. In this program<br />
we will discuss the way an absorption cooling unit operates, and the diagnostic procedures<br />
used to troubleshoot the complete refrigerator system.<br />
(2)<br />
Before we begin extensive troubleshooting<br />
procedures on the cooling unit, let’s take a few<br />
minutes to see how it operates.<br />
(3)<br />
The sealed combustion unit contains a<br />
mixture of ammonia, water and a rust<br />
inhibiting agent. After this solution is<br />
introduced into the coils, this unit is<br />
pressurized with hydrogen gas. When<br />
this system is in operation, the ammonia<br />
vaporizes in the hydrogen atmosphere<br />
and absorbs heat from inside<br />
the refrigerator.<br />
