Testing procedures to determine condition of electrical parts in electrical

control box

1. Turn off ice machine by toggle switch on front of electric box. Make sure spout switch is
closed, have some one turn main breaker off and on while listening at ice machine with all
other equipment quiet. Each time the power is turned on you should hear click of 24V (top)
relay. If you hear the click of relay both the relay and the transformer are OK. If power light
on temperature control is lit the transformer is OK.
2. If raw water pump is running the 120V or 230V (lower) relay is OK. Pump and drive motor
start at the same time.
3. If steps 1 & 2 show components are OK and auger drive motor is running but compressor is
not contactor or time delay may be burnt out. Jump time delay before changing contactor.
Also check voltage across contactor coil before changing contactor. Voltage should be the
same as supply voltage to machine.
