C. Bin Control Check and Cleaning

This icemaker uses a BC with a lever-actuated proximity switch to control the ice level in

the storage bin. No adjustment is required.

To check BC, 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 top and right side panels. Remove the control box cover, then clear any ice

away from BC.

4) Check BC wire harness connections. See Fig. 1.

5) Disconnect BC connector from CB K4 (red) connector.

6) Check for continuity across the wires of BC 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

"IV.C.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

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 "IV.C.2. Bin Control

Cleaning." If BC switch still reads closed, replace BC.

8) Reconnect BC connector to CB K4 (red) connector, then move the control switch to the

"ICE" position. Turn on the power supply.

9) Check that the green "BC CLOSED" LED on CB is on.

10) Allow the icemaker to cycle on. Press and hold the actuator paddle. The yellow "BC

OPEN" LED should be on and the icemaker should shut down according to the chart

below. If it does not, replace CB.
