SERVICE DIAGNOSIS: Condition - No Ice Being Produced
STATUS: NOTHING OPERATES
A. Check: Voltage to the unit, restore it if there is none. Compare to the nameplate.
B. Check: The master switch, switch ON if off.
C. Check the water level in the reservoir. The machine will not run if there is not enough water in the
reservoir. Restore/adjust water level.
STATUS: NOTHING OPERATES
D. Check: The gear motor, if it will not run, the liquid line valve will not open. If no power to it:
Check: The indicator lights on the circuit board, the bin empty light should be ON, the no water light
should be OFF .
1. If the bin empty and no water lights are off, check the transformer.
a. Transformer "load" side should have 12 to 15 volts. If not, check the "line" side. The line
side should have between 208-230 volts. If the line side has the correct voltage and the
load side does not, replace the transformer.
2. If the transformer is good, and the bin empty light is OFF, check the ice level sensors.
a. Remove sensors by sliding them sideways out of the ice chute. Visually inspect them,
clean if needed.
b. Look through the ice chute "eye" hole for something blocking the ice chute.
c. If the unit still does not run, replace the ice level sensors.
d. If the bin empty light is still OFF, check the circuit board. SEE LAST PAGE FOR TESTER
INFORMATION
3. If the transformer is fine, and the "no water" light is ON, check the water level sensor.
a. Check the water level in the reservoir, restore if low. If the water level is ok:
b. Remove the water level sensor from the reservoir and clean the tip if dirty.
CAUTION: THE TIP IS MADE OF GLASS
c. Replace the water level sensor. If the no water light is still on, check that the
"water sen" plug is firmly plugged into the circuit board.
d. If the no water light is still on, SEE LAST PAGE FOR TESTER INFORMATION
e. If after the above, the machine still will not run, replace the water level sensor
