C. Bin Control Check
BC shuts down the icemaker within 10 sec. when ice contacts the thermostatic bulb,
regardless of the cycle at activation.
NOTICE
When the ambient temperature is below 45°F (7°C), BC opens and shuts down the
appliance even if the ice storage bin is empty.
To check BC, follow the steps below.
1) Move the control switch to the "OFF" position.
2) Unplug the appliance.
3) Remove the control box cover. Loosen the control box from the base and slide it out for
easy access. Next, clear any ice away from BC bulb.
4) Use the wiring diagram to locate the 2 wires supplied to BC. Disconnect BC wires.
5) Hold your hand around the bulb to warm it up.
6) Check for continuity across BC wires. If closed, continue to step 7. If open, replace BC.
7) With the multimeter test leads still in place, hold ice in contact with BC bulb. BC should
open within 10sec. If not, BC must be adjusted. Installations at higher altitude locations
are more likely to require adjustment. If BC will not shut down the appliance even after
being adjusted, replace BC.
