ABSTRACT:
An ice bank control system for a beverage dispenser having a mechanical refrigeration system including an inexpensive solid state sensor, preferably a thermistor, located in the ice water bath adjacent to the evaporator coil and connected to a control circuit including a microprocessor which not only controls the ice bank, but also protects the compressor motor. The resistance of the thermistor is measured and then compared to a reference value previously stored in the microprocessor memory.
