Abstract

A control system (40) for an icemaker (10) utilizes a control scheme in which various operating conditions of the icemaker (10) are monitored and the icemaker (10) 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 (10) 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 (18), the rate at which a water pan (26) fills with water while water is delivered to it for subsequent delivery to and over an evaporator (16) to freeze the water into ice on the evaporator (16), and the time required to harvest ice from the evaporator.
