REFRIGERATION COMPONENT DIAGNOSTIC

CHART

Q130/Q170/Q210/Q270 Ice Machines Only
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.
