B. Service Diagnosis
WARNING
• The appliance should be diagnosed and repaired only by qualied service
personnel to reduce the risk of death, electric shock, serious injury, or re.
• Risk of electric shock. Use extreme caution and exercise safe electrical practices.
• Moving parts (e.g., fan blade or auger) can crush and cut. Keep hands clear.
• CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are
securely in place after the appliance is serviced. Make sure that none have fallen
into the ice storage bin.
• Make sure all food zones in the icemaker and ice storage bin are clean after
service.
1. Ice Production Check
To check production, prepare a bucket or pan to catch the ice and a set of scales to
weigh the ice. After the appliance has operated for 10 to 20 minutes, catch the ice
production for 10 minutes. Weigh the ice to establish the batch weight. Multiply the
batch weight by 144 for the total production in 24 hours. When conrming production or
diagnosing low production, reference production information to the performance data
charts found in "VII.A. Specication and Performance Data Sheets."
