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 water curtain must be installed (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.
Ohm Test
1. Disconnect the bin switch wires from the control board.
2. Connect an ohmmeter to the disconnected bin switch.
3. Cycle the bin switch open and closed numerous times by opening and closing the
water curtain.
NOTE: To prevent misdiagnosis:
• Always use the water curtain magnet to cycle the switch (a larger or smaller magnet will
affect switch operation).
• Watch for consistent readings when the bin switch is cycled open and closed (bin switch
failure could be erratic).
