Factory set. DCM-270BAH(-OS) does not use a bin control with an infrared sensor.
The appliance uses a bin control with a mechanical micro-switch for ice level control.
3. Drain Frequency Control (S1 dip switch 4)
The appliance is factory set for optimum performance with the 1-in-1 drain cycle (S1 dip
switch 4 in the "OFF" position). This setting allows for removal of sediment from the
evaporator without interrupting the icemaking process. NOTICE! Do not adjust S1 dip
switch 4 out of the factory default position. This dip switch must be left in the
factory default position or the appliance will not operate correctly.
