PROBLEM
[11] Cloudy cubes
[12] Freeze cycle time is too
long
[13] Icemaker will not stop
when Bin is filled with ice
[14] Abnormal Ice
[15] Some cells on the
evaporator form no ice
CHECK
a) Water Quality
b) Noz zle
c)
Water Recirculation
System
a) Ambient temperature
b) Condenser inlet / outlet
c) Thermistor
d) Refrigerant Circuit
e) Fan Motor
f) Condenser
a) Bin Control Thermostat
a) Nozzle
b) Pump Motor
c) Pump Motor Impeller
d) Compressor
e) Refrigerant Circuit
a) Nozzle
POSSIBLE CAUSE
1. High hardness or contains
impurities
1. Clogged
2. Misaligned Nozzle and
Water Tank
1. Scaled up
2. Water leaks
1. Too high ( freeze cycle
will be extremely long at
more than 40°C / 104°F)
1. Blocked. Bad air
circulation greatly reduces
ice production capacity
1. Out of position or loose
attachment
2. Leads short-circuit
1. Refrigerant leak or
restriction
2. Undercharged
1. See [3]
1. Blocked
1. Fused contacts
1. Clogged
2. Misaligned Nozzle and
Water Tank
1. Bearing worn
1. Defective or bound
impeller
1. Inefficient.
1. Leak or restriction
1. Clogged
2. Misaligned Nozzle and
Water Tank

REMEDY
1. Install a water filter or
scale treatment
1. Clean system (see page
8-1)
2. Place in correct position
1. Clean or remove scale
2.Check connections for
water leaks and repair
1. Check for recommended
ambient temperature
1. Clean condenser
1. Refer to "Removing The
Evaporator Thermistor" (see
page 4-8)
2. Check continuity (see
page 5-2)
1. Check with a leak
detector. Repair & recharge.
Replace the refrigerant
drier.
2. Check for leaks and
