Abstract: A control system for an icemaker utilizes a control scheme in which various operating conditions of the icemaker are monitored sand the icemaker is shut down if a fault condition is sensed. In response to detection of the fault condition, steps are taken to actively remove the fault. Restarting of the icemaker is then attempted if sensors indicate that normal continued operation should be possible. The operating conditions sensed include the temperature of refrigerant at an outlet from a condenser, the rate at which a water pan fills with water while water is delivered to it for subsequent delivery to and over an evaporator to freeze the water into ice on the evaporator. and the time required to harvest ice from the evaporator.

Abstract: An ice/beverage dispenser is characterized by an ice/beverage dispensing machine having an integral ice making capacity. An icemaker of the dispenser and the ice and beverage dispensing portion share an evaporator that that is utilized both for chilling beverage water for dispensing and for making ice. The evaporator is efficiently utilized in that one side of it is used for making ice and both sides of it are used for chilling water. The present invention uses a processor based control circuit that operates the refrigeration system between ice-making and water chilling modes in such manner as to ensure that cold beverages will always be served. The ice/beverage dispenser also includes a system for quickly combining and separating the ice making and beverage dispensing water supply, water drain and electrical functions.
