Completed commercial ice machine repair and preventive maintenance on a Hoshizaki KMD-505MAJ ice machine after the customer reported the unit was not producing ice properly. Upon inspection, the condenser coil was found to be heavily impacted with dirt and debris, significantly restricting airflow through the condenser. The restricted airflow caused elevated condensing temperatures, reducing refrigeration efficiency and extending ice production times.
Performed a thorough condenser coil cleaning to restore proper airflow and heat rejection. After cleaning, the ice machine was monitored through a complete freeze and harvest cycle to verify proper operation. Refrigeration system performance was tested before and after the service. Final operating pressures measured approximately 55 PSIG suction and 275 PSIG discharge during the freeze cycle, which are within Hoshizaki’s recommended operating range for the existing ambient conditions. Harvest pressures were also verified and found to be normal.
The freeze cycle was timed at 31 minutes, which falls within the manufacturer’s specifications. The machine completed a normal harvest cycle and resumed dropping ice properly, confirming that condenser airflow restriction was the primary cause of the production issue.
At the time of departure, the commercial ice machine was operating normally with proper refrigeration pressures, acceptable freeze cycle duration, and normal harvest operation. Regular preventive maintenance, including routine condenser coil cleaning, is recommended to maximize ice production, improve energy efficiency, reduce compressor operating temperatures, and help prevent unexpected breakdowns in commercial ice machines serving restaurants, hotels, bars, and other food service facilities. Setpoint Services will follow up with the customer over the next several days to verify the machine continues producing ice normally.
