Operational Analysis Table
GENERAL
These tables must be used with charts, checklists and
other references to eliminate refrigeration components
not listed on the tables and external items and
problems which can cause good refrigeration
components to appear defective. The tables list
different defects that may affect the ice machine’s
operation.
The items listed below must be followed to provide
accurate data:
1. Before starting, see “Before Beginning Service”
for a few questions to ask when talking to the ice
machine owner.
2. All doors and panels must be in place.
3. Initial freeze cycle is not used for diagnostics.
4. Wait 3 minutes into the second freeze cycle
before monitoring temperatures. This will allow
the system to stabilize and minimizes fluctuations.
