TROUBLE SHOOTING
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.
Replace fuse or reset breaker.
Check circuit for overload condition.
Ice machine off because bin is full of
ice.
Use ice or move ice away from bin
level probe.
Ice machine off because bin level
probe is defective.
Replace bin level 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.
Compressor is not
operating. Water
pump and other
components are
operating normally.
See compressor test
procedure for more
information.
Ice-Clean switch in "Clean" position.
Move switch to "Ice" position.
High pressure cut-out open on air
cooled models. Condenser dirty.
Clean condenser and reset high
pressure cut-out. Confirm proper
operating pressures.
High pressure cut-out open on air
cooled models. Air circulation through
condenser is insufficient or hot air is
recalculating 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 on liquid
cooled models. Coolant liquid
interrupted or insufficient
Restore adequate coolant liquid
supply and reset high pressure cut
out. Confirm proper operating
pressures.
High pressure cut-out open on liquid
cooled models. Interior of condenser
has a mineral build-up.
Clean or replace condenser.
High pressure cut-out open.
Refrigeration system is overcharged.
Remove refrigerant and recharge
the system to specifications.
Compressor thermal protector open
because of low voltage condition.
Allow thermal protector to reset.
Measure voltage at contactor while
compressor is running. Correct
power supply problem if voltage is
lower than specified on the ice
machine electrical plate. See
compressor test procedure for more
information.
Compressor thermal protector open
because of defective run capacitor.
Replace run capacitor. See
compressor test procedure for more
information.
Contactor is defective.
Check for voltage at coil terminals.
Replace contactor if it does not
close when the coil is energized.
Compressor start capacitor or relay
defective
Test and replace these parts if
defective. See compressor test
procedure for more information.
