7) "GM" LED and "COMP" LED are on. Use an object to cover the infrared sensor lens
at the bottom of the icemaker. If the bottom of the icemaker is not accessible in your
application, remove the thumbscrew securing the infrared sensor housing, remove the
housing from the base, then cover the infrared sensor lens. See Fig. 18. The yellow
LED on the infrared sensor turns on. The yellow LED ashes when ice is at the outer
limit of its range and turns steady as ice nears. After the yellow LED turns on (ashing
or steady), the infrared sensor shutdown delay timer starts counting down based on
S1 dip switch 1, , and 3 setting. The compressor should de-energize immediately after
the shutdown delay timer expires. 5 minutes later, the gear motor and fan motor should
de-energize.
8) Remove the object covering the infrared sensor. If you removed the infrared sensor
housing from the base, replace it in its correct position, and secure it with the
thumbscrew.
9) Move the power switch to the "OFF" position. Turn off the power supply, then proceed
to "II.K.. Mechanical Backup Bin Control Check."
