D. Bin Control Check
Bin Control Check
When the actuator paddle is not engaged BC is closed and the icemaker produces ice.
With CB S1 dip switch 7 placed in the "OFF" position, BC is used as a stand-alone bin
control. The stand-alone application should only be used in standard ice storage bin
applications. When ice lls the chute and engages the actuator paddle, BC opens and
starts CB shutdown sequence.
1) Remove the front panel and move the power switch to the "OFF" position, then unplug
the appliance from the electrical outlet.
2) Remove the rear cover. Next remove the 12 pin connector plug from the control box.
3) Open the ice storage bin door so that you can access the actuator paddle located in the
top of the bin. See Fig. 2.

4) With actuator paddle not engaged, check for continuity across BC GY wires (proximity
switch) in 12 pin connector plug. BC closed. If BC continuity indicates open BC with the
actuator paddle engaged, replace BC (proximity switch).
5) Press the actuator paddle located in the top of the bin to the right (actuator paddle
engaged). Check for continuity across BC GY wires (proximity switch) in 12 pin
connector plug. BC open. IfBC continuity indicates closed BC with the actuator paddle
engaged, replace BC (proximity switch).
6) Reconnect the 12 pin connector plug to the control box.
