Bin Switch
Function
Bin switch operation is controlled by the movement of the
water curtain. The bin switch has two main functions:
1. Terminating the harvest cycle and returning the ice
machine to the freeze cycle.
This occurs when the bin switch is opened and closed
again within 30 seconds of opening during the harvest
cycle.
2. Automatic ice machine shut-off.
If the storage bin is full at the end of a harvest cycle,
the sheet of cubes fails to clear the water curtain and
holds it down. After the water curtain is held down
for 30 seconds, the ice machine shuts off.
The ice machine remains off until enough ice is
removed from the storage bin to allow the sheet of
cubes to drop clear of the water curtain. As the water
curtain swings back to the operating position, the bin
switch closes and the ice machine restarts.
Important
The ice damper must be up (bin switch closed) to start
ice making.
Check Procedure
1. Cycle the toggle switch OFF.
2. Watch the curtain light on the control board.
3. Move the water curtain upward, toward the
evaporator. The bin switch must close. The curtain
light “on” indicates the bin switch has closed properly.
4. Move the water curtain away from the evaporator.
The bin switch must open. The curtain light “off”
indicates the bin switch has opened properly.
