This appliance uses a lever-actuated proximity switch to control the ice level in the 
storage bin. No adjustment is required. 

To check, 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. Clear any ice away from BC.

4) Check BC wire harness connections.

5) Disconnect BC wire harness connector from CB CN11 connector.

6) Check for continuity across the wires of BC wire harness connector. When the actuator 

paddle is not engaged, BC switch is closed. If open, check that the wire harness 
connector is properly connected and that the actuator paddle is not sticking. Clean if 
necessary. See "II.D.2. Bin Control Cleaning." If BC switch still reads open, replace BC. 

7) Press and hold the actuator paddle; check for continuity across the wires of BC wire 

harness connector. When the actuator paddle is engaged, BC switch is open. If closed, 
check that the actuator paddle is not restricted. Clean if necessary. See "II.D.2. Bin 
Control Cleaning." If BC switch still reads closed, replace BC.

8) Reconnect BC wire harness connector to CB CN11 connector, then move the control 

switch to the "ICE" position. Turn on the power supply.

9) Allow the icemaker to cycle on. Press and hold the actuator paddle for at least 

10 seconds. The icemaker should shut down. If it does not, replace CB.
Note: If BC is engaged (open) while the water tank is opening after the power supply 

is turned on (or after the "RESET" button is pressed), shutdown does not start: 
Shutdown occurs 10 seconds after actuator motor's internal position sensor 
indicates water tank is fully open.
