Problem

Likely Cause

Probable Solution

No power to unit

Power disconnected

Check breaker or fuse. Reset or

replace, restart and check

 

 

No power to controller

Transformer open

Replace transformer

Shut down on maximum

 

 

water fill time - water light

Water shut off

Restore water supply

flashing

 

 

 

Water leak

Check curtain, sump

 

Dirty condenser

Clean condenser

 

Restricted location, intake air too

Eliminate restriction, have machine

 

hot or blocked

moved

 

Evaporator thermistor not sensing

Check thermistor

 

properly

 

 

Very long freeze cycle

Spray jets dirty

Remove spray platform and clean

spray jets

 

 

 

 

Inlet water valve leaks through

Check inlet water valve

 

during freeze

 

 

 

Low on refrigerant

Check cube formation,

 

 

Check for bleed thru from / missing

 

Connected to hot water

check valve in building water

 

 

supply

 

Spray pump not pumping

Check pump motor

 

Fan motor not turning

Check fan motor, check fan blade,

 

check controller for voltage output

 

 

 

Pump hose disconnected

Check hose

 

 

Add access valve, add refrigerant

 

Very low on refrigerant

as a test. If unit makes ice, find and

 

 

correct leak.

 

 

Check compressor start

Cannot make ice

 

components, check PTCR

 

Compressor not operating

resistance and temperature

 

Check compressor voltage

 

 

 

 

Check compressor windings
