5) Disconnect the bin control at the 2-pin connector attached to the black wires coming
from the K1 connector (pins 4 & 5) on the control board.
6) Check for continuity across the bin control leads. When calling for ice, the bin control
proximity switch should be closed. If open, replace the bin control. Activate the bin
control actuator (press the actuator in), check for continuity across the bin control
leads. The bin control proximity switch should be open. If closed, replace the bin
control.
7) Reconnect the 2-pin connector. Allow the machine to cycle into the freeze cycle. In
the first 5 minutes of the freeze cycle, activate the bin control actuator (press the
actuator in). The “POWER OK” LED should flash and the machine should turn off. If
not, replace the control board.
6. SWITCHES
Control Switch
The Control Switch is located at the left front of the unit. Remove the Air Filter to access
the Control Switch. This switch is used to place the machine into one of three modes:
“OFF” (center position), “ICE” (right position), and “WASH” (left position).
1) “OFF”
In the “OFF” position, no power is supplied to
the unit. However, to avoid any possible risk of
electrical shock, disconnect the power before
servicing.
2) “ICE”
This position applies power to the unit causing
the automatic icemaking process to begin.
Refer to “II. 2. SEQUENCE OF OPERATION”
for further details.
3) “WASH”
When the Control Switch is placed in the “WASH”
position, power is supplied to the Pump Motor
and Cleaning Water Valve. This allows cleaning
and/or sanitizing solutions (see “VI. CLEANING
AND MAINTENANCE INSTRUCTIONS”) to
circulate throughout the water system and down
the inside and outside of the Evaporator plates.
