2. Shutdown Diagnosis
When the appliance is running, hold ice in contact with the thermostatic bulb. BC switch
opens within 10 sec., shutting down the appliance. BC is factory set, and generally
no adjustment is required. However, adjustment may be needed in some conditions,
particularly at higher altitude locations. Diagnosis: See "II.E. Bin Control Check." CB red
K4 connector must have the jumper in place. When the jumper is in place, the green "BC
CLOSED" LED remains on. If the jumper is not in place, yellow "BC OPEN" LED turns
on and the icemaker turns off and remains off until the jumper is replaced in its original
position.
NOTICE!
CB red K4 connector jumper (4A4883G01) must be in place.
