Abstract
An ice producing machine that has a cylindrical evaporator, a compressor that circulates refrigerant supplied to the evaporator, an auger that removes ice from the evaporator and an ice bin for holding the ice. Potential damage to the machine that might result from abnormal loading of the motor that drive the auger is prevented by monitoring the motor current and turning off the motor and compressor before abnormal loading can cause damage. False ice bin not full interpretations are avoided by setting the threshold of a light detector that senses whether the ice bin is full or not full to slightly less than the voltage developed by the light detector when subjected to ambient light only.
