8) "GM" and "COMP" LEDs are on. Use an object to cover the lens. BC1 yellow LED turns
on (flashing or steady). BC1 yellow LED flashes when ice is at the outer limit of its
range and turns steady as ice nears. After BC1 yellow LED turns on (flashing or steady),
BC1 shutdown delay timer starts . See "III.B.2. BC1 (Infrared Sensor) Shutdown Delay
(S1 dip switch 1, 2, 3)." PDS should de-energize immediately after the shutdown delay
timer terminates. 5 min. later, GM should de-energize.
Diagnosis: If BC1 yellow LED is not on after covering the lens, replace BC1. If the
appliance remains on after BC1 shutdown delay timer terminates and the 5-min. ice
purge timer terminates, replace CB. If BC1 fails to shut down the icemaker and the level
of ice activates BC2, the icemaker shuts down and a 9-beep alarm sounds. To reset,
move the power switch to the "OFF" position, and then back to the "ON" position.
9) Remove the object covering the lens. If you removed BC1 housing from the base,
replace it in its correct position, and secure it with the thumbscrew.
10) Move the power switch to the "OFF" position. Unplug the icemaker from the electrical
outlet, then proceed to "II.D.2. Bin Control 2 (mechanical backup) Check."
