(2)Defrost Timer
The defrost cycle starts when the Float Switch opens and completes the freeze cycle. But the Defrost Timer does not start counting until the Ther- mistor senses 48°F at the Evaporator outlet. The period from the end of the freeze cycle up to the point of the Thermistor's sensing varies depending on the ambient and water temperatures.
(3)High Temperature Safety - 127 ± 7°F
The temperature of the suction line in the refrigerant circuit is limited by the High Temperature Safety.
During the defrost cycle the Evaporator temperature rises. The Thermistor senses 48°F and starts the Defrost Timer. After the Defrost Timer counts down to zero, the normal freeze cycle begins. If the Evaporator temperature
continues to rise, the Thermistor will sense the rise in temperature and at 127
± 7°F the Thermistor operates the High Temperature Safety.
This High Temperature Safety shuts down the circuit and the icemaker auto- matically stops. To reset the safety, turn the power off and back on again. This High Temperature Safety protects the unit from excessive temperature.
(4)Low Water Safety
The Controller Board checks the position of the Float Switch at the end of the initial one minute water fill cycle and at the end of each defrost cycle.
If the Float Switch is in the up position (electrical circuit closed), the Controller Board changes to the ice making cycle. If the Float Switch is in the down position (electrical circuit open), the Controller Board changes to a one minute water fill cycle before starting the ice making cycle.
