C. Bin Control Check and Cleaning
1. Bin Control Check
To check the bin control, follow the steps below.
1) Turn off the power supply.
2) Remove the front panel, then move the control switch to the "OFF" position.
3) Remove the control box cover, then clear any ice away from the bin control.
4) Disconnect the wire connector from the control board K1 nine-pin connector. See "II.
C.1. Control Board Layout."
5) Check for continuity across the black wires (4 & 5) of the wire connector. When the
actuator paddle is not engaged, the lever-actuated bin control switch is closed. If the
lever-actuated bin control switch reads open, check that the harness connector is
secured to the bin control switch connector and that the actuator paddle is not sticking.
See Fig. 5. Clean if necessary. See "IV.C.2.b) Bin Control Cleaning." If the bin control
switch still reads open, replace the bin control.
6) Press the actuator paddle, check for continuity across the black wires (4 & 5) of the wire
connector. When the actuator paddle is engaged, the lever-actuated bin control switch
is open. If closed, check that the actuator paddle is not restricted. Clean if necessary.
See "IV.C.2.b) Mechanical Bin Control Cleaning." If the bin control switch still reads
closed, replace the bin control.
7) Reconnect the wire connector to the control board K1 nine-pin connector, then move
the control switch to the "ICE" position. Turn on the power supply.
8) Check that the "POWER OK" LED on the control board is on (not flashing).
9) During the 1-minute fill cycle, press the actuator in and hold it in for 15 seconds. Check
that the "POWER OK" LED flashes and, after the actuator is held in for 15 seconds,
the water tank drains. After the water tank drains and the float switch opens, the unit
should shut down. If the unit does not shut down after the water tank drains, check the
float switch. See "IV.D. Float Switch Check and Cleaning." If the float switch checks out
and the unit will not shut down after the water tank drains, replace the control board.
See "V.N. Removal and Replacement of Control Board."
2. Bin Control Cleaning
Scale may build up on the bin control. Scale can cause the actuator paddle to stick. In
this case, the bin control should be cleaned.
WARNING
CHOKING HAZARD:
Ensure all components, fasteners, and thumbscrews are
securely in place after the unit is serviced. Make sure that none have fallen into
the storage bin.
1) Turn off the power supply.
2) Remove the front panel, then move the control switch to the "OFF" position.
3) Clear any ice away from the bin control.
