2. Bin Control 2 (BC2) (mechanical backup) Check
When the spout cover is closed, BC2 is closed and the icemaker produces ice. With S1
dip switch 7 placed in the "ON" position, BC2 is used as a backup bin control safety.
When BC1 fails to shut down the icemaker and ice lls the chute and disengages the
spout cover, BC2 opens and CB immediately shuts down the icemaker and sounds a
9-beep alarm.
1) Move the power switch to the "OFF" position, then unplug the icemaker from the
electrical outlet.
2) If not already removed, remove the front panel, top panel, and control box cover.
3) Remove the spout spring from the spout. See Fig. 4.

4) Plug the icemaker into the electrical outlet. Move the control switch to the "ICE" position,
then move the power switch to the "ON" position.
5) 30 seconds after the upper oat switch closes, the control board "GM" LED turns on.
After "GM" LED turns on, press the "SERVICE" button on the control board to bypass
the 5-minute compressor delay. WARNING! Risk of electric shock. Care should be
taken not to touch live terminals.
6) "GM" LED and "COMP" LED are on. Open the spout cover slightly. See Fig. 5.
"GM" LED and "COMP" LED turn off within 10 seconds and the control board sounds a
9 beep alarm. Close the spout cover.
7) Move the power switch to the "OFF" position, then unplug the appliance from the
electrical outlet. Note: The control board alarm resets when power is turned off.
8) Replace the spout spring in its correct position.
9) Replace the control box cover and top panel in their correct positions.
10) Plug the icemaker back into the electrical outlet. Move the control switch to the "ICE"
position, then move the power switch to the "ON" position to start the automatic
icemaking process.
11) Replace the front panel in its correct position.
