D. Bin Control

CAUTION

When the ambient temperature is below 45°F (7°C), the thermostatic bin control switch opens and shuts down the icemaker even if the ice storage bin is empty. When the thermostat is set in the prohibited range, the icemaker operates continuously even if the ice storage bin is filled with ice. Setting in the prohibited range may result in severe damage to the icemaker.

The thermostatic bin control switch is a temperature controlled switch used to control the level of ice in the bin. It is in line with the power supply to the control switch.

The thermostatic bin control switch shuts down the unit within 10 seconds when ice contacts the thermostatic bulb, regardless of the cycle at activation. The bin control is factory set, and generally no adjustment is required. However, adjustment may be needed in some conditions, particularly at higher altitude locations. For further details, see "IV.C. Bin Control Check."

E. Float Switch

The float switch is used to determine that there is sufficient water in the tank after the

1‑minute fill cycle and after each harvest cycle. The float switch is also used to determine that the appropriate volume of water has been converted into ice before switching out of the freeze cycle. No adjustment is required.

F. Thermistor

The thermistor is used as a harvest control sensor. The thermistor's resistance varies depending on the suction line temperature. The control board monitors the resistance to start the harvest timer. No adjustment is required.

G. Control Switch

The control switch has three positions: "OFF" for power off, "ICE" for icemaking, and "WASH" to activate the water pump when cleaning and sanitizing.
