Refrigeration Component Diagnostics
All electrical and water related problems must be 
corrected before these charts will work properly. These 
tables must be used with charts, checklists and other 
references to eliminate refrigeration components not 
listed and external items and problems that will cause 
good refrigeration components to appear defective.
The tables list four different defects that may affect the 
ice machine’s operation.
NOTE: A low-on-charge ice machine and a starving 
expansion valve have very similar characteristics and 
are listed under the same column.
