D. Bin Control Check
1. Bin Control Check
This appliance uses a mechanical bin control to control the ice level in the storage bin.
No adjustment is required.
To check BC, follow the steps below.
1) Remove the louver, move the control switch to the "OFF" position, then unplug the
icemaker from the electrical outlet.
2) Clear any ice away from BC.
3) Remove the control box, then disconnect CB K1 connector from CB.
4) Check for continuity across BC leads. When the actuator paddle is not engaged,
BC switch is closed. If open, check that the actuator paddle is not sticking. Clean if
necessary. See "II.D.2. Bin Control Cleaning." If BC switch still reads open, replace BC.
5) Reach under the evaporator and water tank and press and hold the actuator paddle;
check for continuity across the wires of the 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 "II.D.2.Bin Control Cleaning." If BC switch still reads closed,
replace BC.
6) Reconnect CB K1 connector to CB. Next, move the control switch to the "ICE" position.
7) Plug the icemaker into the electrical outlet.
8) Allow the icemaker to cycle into the freeze cycle. Once in the freeze cycle, press and
hold the actuator. View CB LEDs, the CB "POWER OK" LED should start ashing and
the icemaker should shut down according to the chart below. If not, check that the
BC/CB connector is securely reconnected. If so, replace CB.
Cycle at Bin
Control Activation
Shutdown
Fill Cycle 15 sec. after activation.
Harvest Cycle 15 sec. into the freeze cycle.
Freeze Cycle 15 sec. after activation if activated at least 15 sec. before the 5-min. short cycle
protection timer terminates (timer starts when the thermistor temperature achieves
36°F (2°C)(5.5 kΩ or more)). Otherwise, at the end of the next harvest cycle.
9) Replace the control box and louver in their correct position.
