Refrigeration Diagnostics
BEFORE BEGINNING SERVICE
Ice machines may experience operational problems
only during certain times of the day or night. A machine
may function properly while it is being serviced, but
malfunctions later. Information provided by the user can
help the technician start in the right direction, and may be
a determining factor in the final diagnosis.
Ask these questions before beginning service:
• When does the ice machine malfunction? (night, day,
all the time, only during the Freeze cycle, etc.)
• When do you notice low ice production? (one day a
week, every day, on weekends, etc.)
• Can you describe exactly what the ice machine seems
to be doing?
• Has anyone been working on the ice machine?
• During “store shutdown,” is the circuit breaker, water
supply or air temperature altered?
• Is there any reason why incoming water pressure
might rise or drop substantially?
