a) Thermostatic Bin Control (TBC):
When the appliance is running, hold ice in contact with the thermostatic bulb. TBC
switch opens within 10 sec., shutting down the appliance. TBC 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.D.1. Thermostatic 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.
