Manitowoc URF0140A Technician's Handbook

Part Number 000014797 Rev02 05/18 133
Abnormal temperatures
Higher than normal freeze cycle temperatures.
• A dirty filter or condenser will result in higher than
normal temperatures. Always clean the filter and
condenser before diagnosing the refrigeration system.
• Hot water entering the ice machine will result in high
suction and discharge line temperatures in the freeze
cycle.
Capillary tube failures or low refrigerant charge will always
result in a starving evaporator.
• An obstructed capillary tube or low refrigerant charge
will have a suction line temperature higher than
normal.
• An obstructed capillary tube or low refrigerant charge
will have a discharge line temperature lower than
normal.
• An obstructed capillary tube will not effect the
discharge line temperature during the harvest cycle.
A low freeze and discharge line temperature in the
freeze cycle with a normal harvest cycle discharge line
temperature indicates an obstructed capillary tube.
• Low refrigerant charge will have both the suction and
discharge line temperatures lower than normal in the
freeze and harvest cycles.
