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?
