6) Press the actuator paddle located in the top of the chute. Comp (LLV and SLV on MLH
model) and GM de-energize within 10 sec.
Diagnosis: If BC(2) does not open and the icemaker continues to make ice
(mechanical stand-alone or backup), CB fails to shutdown icemaker within 10 sec. or
go into alarm, check that the actuator paddle is engaged. Check for continuity across
BC(2) wires. If BC(2) contacts are found open and the icemaker continues to make
ice or CB fails to go into alarm (BC2), replace CB. If BC(2) is closed with the actuator
paddle engaged, replace BC(2).
WARNING! On CB 2A8054-01, If dip switch 9 is in the "OFF" position, the shut
down delay is too long. This could lead to icemaker movement or ice overow.
7) Move the power switch to the "OFF" position and turn off the power supply.
8) Replace the chute assembly and strap in their correct positions.
9) Move the power switch to the "ON" position.
10) Replace the control box cover, top panel, and front panel in their correct positions.
11) Turn on the power supply to start the automatic icemaking process.
