5) 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.

prohibited range might cause severe damage to the icemaker resulting in

No adjustment is required under normal use, as the Bin Control is factory-adjusted.
Adjust it, if necessary, so that the icemaker stops automatically in approximately 6 to 10
seconds after ice contacts the Bin Control Thermostat Bulb.

[e] CHECKING 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.

After the 1 minute ± 5 second water supply cycle and the 2 minute ± 10 second defrost
cycle, the unit should start the freeze cycle.

(ii) After the above step (i), disconnect the Float Switch leads from the Controller Board
within the first 5 minutes of the freeze cycle.
The unit should go into the defrost cycle after the first 5 minutes ± 20 seconds of
