4)Check for resistance between the thermistor leads. Normal reading is within 4.7 to 6.2 kΩ. Replace the thermistor if it exceeds the normal reading.

5.BIN CONTROL

This machine uses a lever-actuated proximity switch (mechanical bin control) to control the ice level in the storage bin. No adjustment is required.

[a] EXPLANATION OF OPERATION

The bin control is connected to the K1 connector (pins 4 & 5) on the control board. When the bin control is calling for ice (proximity switch closed; “POWER OK” LED on), the control board continues icemaking operations. When the bin control is activated in the bin full position (proximity switch open; “POWER OK” LED flashing), the control board drains and shuts down the unit. However, to prevent incomplete batches of ice from forming on the evaporator, the control board will only shut down the machine during the freeze cycle before the five minute timer expires. The five minute timer starts counting down when the thermistor temperature reaches 36°F (2°C). If, during the freeze cycle, ice pushes in the lever after the five minute timer expires, the control board will allow the machine to complete the freeze cycle and the following harvest cycle before shutting down the machine.

When the bin control is activated, the “POWER OK” LED flashes. There is a delay before the shutdown sequence begins. The delay varies depending on the cycle the icemaker is in at the time of activation. For details, see the table below.

Cycle at Bin Control Activation Delay Before Shutdown Sequence Begins

Fill Cycle

15 seconds

Harvest Cycle

15 seconds after the next freeze cycle starts

Freeze Cycle

15 seconds if the bin control is activated between the

 

beginning of freeze and termination of the 5-minute short

 

cycle protection timer (timer starts when the thermistor

 

temperature drops to 36°F (2°C) (5.5 kΩ or more)). After this

 

time, the unit will not shut down until the next harvest cycle is

 

complete.

[b] BIN CONTROL CHECK PROCEDURE

1)Clear any ice away from the bin control.

2)Make sure the control switch is in the “ICE” position.

3)Check that the “POWER OK” LED on the control board is on.

4)Activate the bin control actuator (press the actuator in). Check that the “POWER OK” LED flashes.
