5. Bin Control Selector (S1 dip switch 7)
The appliance is factory set for infrared sensor bin control operation. No adjustment is
required. In the factory default position (S1 dip switch 7 in the on position), the gear motor
delay after the upper oat switch closes is 30 sec. WARNING! Do not place S1 dip
switch 7 in the off position. This could lead to icemaker movement or ice overow.
