[i] CHUTE SWITCH
The Chute Switch consists of a microswitch and a band securing the Spout and Chute.
When the Bin Control Switch breaks down, the band opens and presses the button on the
microswitch (contacts open) to stop the icemaker (error code: EL).
To restart the icemaker, remove ice from the Spout and Chute, and move the Operation
Switch to the “STOP” position, then to the “RUN” position.

[j] DEICING HEATER (BELT HEATER) - FM-481AGE-HCN, FM-300AFE-HCN ONLY
The Deicing Heater is provided to reduce the load of ice passing the Extruding Head and
prevent vapor lock. If the Extruding Head is clogged with ice, a creaking sound will be
heard, or the Evaporator Cylinder will expand to break the soldered joint between the
Cylinder and Copper Tube, where condensate may enter and freeze to crush the Copper
Tube. In the previous models, the Flange was welded to secure the Spout, which may
cause cracked welded joints.
