Problems and Solutions
PROBLEM
POSSIBLE CAUSE
SOLUTION
Ice machine is not
operating.
On-Off switch in "Off" position
Move switch to "On" position.
No power at ice machine. Circuit
protector open.
Reset breaker. Check circuit for
overload condition.
Ice machine off because bin is full of ice. Use ice or move ice away from bin
probe.
Ice machine off because bin probe is
defective.
Replace bin probe.
Ice machine off as if bin is full. Ambient
temp below 50°F (10°C).
Ambient temperature must be 60°F
(15°C) minimum.
Condenser fan motor is
not operating on air-
cooled models.
Compressor is operating
Ice-Clean switch in "Clean" position.
Move switch to "Ice" position.
High pressure cut-out open on air
cooled models. Condenser dirty.
Clean condenser. Confirm proper
operating pressures.
High pressure cut-out open on air
cooled models. Air circulation through
condenser is insufficient or hot air is
recirculating through the condenser.
Provide adequate spacing between
the ice machine and walls, ceilings
or other equipment. See installation
instructions for spacing
requirements. Confirm proper
pressures.
High pressure cut-out open.
Refrigeration system is overcharged.
Remove refrigerant and recharge the
system to specifications.
Compressor thermal protector is open
because of low voltage condition.
Allow thermal protector to reset.
Measure voltage at relay while
compressor is running. Correct
power supply problem if voltage is
lower than specified on the ice
machine electrical plate.
Compressor thermal protector is open
because of defective run capacitor.
Replace run capacitor.
Relay is defective.
Check for voltage at terminals.
Replace relay if it does not close
when the coil is energized.
Compressor start capacitor or relay
defective
Test and replace these parts if
defective.
Compressor is defective.
Replace compressor.
Condenser fan motor is
not operating on air-
cooled models.
Compressor is operating
Fan motor protector open.
Replace motor if it does not run
when cool or at normal operating
conditions.
Fan motor defective
Replace motor.
Water plate re-opens
immediately after closing
"Plate up" switch lever is not being
pushed up completely.
Adjust "Plate up" switch actuator
near water plate until it releases the
switch lever completely.
Water plate is prevented from closing by
some obstruction such as ice remaining
on the water plate surface.
Eliminate obstruction. Adjust the
evaporator temperature probe so all
ice is out of the evaporator before
the water plate begins to close.
