ICE DAMPER AND HALL EFFECT SWITCHES
Damper Door
FUNCTION
Opens and closes as ice passes from the ice chute to
the bin. A metal lever attached to the damper
interrupts the magnetic field sensed by the hall effect
switches as the damper opens and closes.
Hall Effect Switch #1 -
Operational Sensing
This switch will open and re-close in conjunction with
the ice damper as ice is discharged from the
evaporator. The control board must see this switch
open and close at least once every 90 seconds during
the freeze cycle.
Hall Effect Switch #2 -
Shut-Off and Restart
This switch also works in conjunction with the ice
damper. When the switch opens, the ice machine
stops immediately. The ice machine restarts when the
switch re-closes and the five minute delay period
expires.
FUNCTION TEST
Place toggle switch in OFF position. HES#1 and
HES#2 lights will energize. Move ice damper slowly to
open position.
• HES#1 light de-energizes, HES#2 remains
energized.
• HES#2 light de-energizes as damper continues to
open.
Move damper slowly to closed position HES#2
energizes, HES#1 remains de-energized.
HES#1 energizes as the damper continues to close.
