6) Bin Control
CAUTION
When the ambient temperature is below 45°F, the bin control thermostat operates to
stop the icemaker even if the ice storage bin is empty. When the thermostat is set in the
prohibited range, the icemaker operates continuously even if the ice storage bin is
filled with ice. Setting in the prohibited range might cause severe damage to the
icemaker resulting in failure.
No adjustment is required under normal use, as the bin control is factory-adjusted. Adjust it, if
necessary, so that the icemaker stops automatically within 10 seconds after ice contacts the bin
control thermostat bulb.
[e] Checking the Controller Board
1) Visually check the sequence with the icemaker operating.
2) Visually check the controller board by using the following procedures:
(i) Adjust the defrost timer to minimum position.
Disconnect the thermistor from the controller board.
Connect a 1.5 kΩ - 3.5 kΩ resistor to the connector K3 (pins #1 and #2), and energize the unit.
After the 1 minute ± 5 second water supply cycle and the 2 minute ± 10 second defrost cycle, the
unit should start the freeze cycle.
