ABSTRACT:
An icemaker assembly includes an ice tray having an ice forming compartment, a water line configured to advance water from a water source to the ice tray, a valve operable to selectively block advancement of water through the water line while an actuation signal is generated, a control system operable to generate the actuation signal for a water advancement period, a water level detection system for determining if a level of water in the ice forming compartment is below a threshold value and generating a control signal in response thereto. The control system is further operable to alter a magnitude of the water advancement period in response to generation of the control signal. Water is initially advanced into the ice forming compartment for a first period of time during a first ice making cycle by opening the valve. If it is determined that the level of water in the ice forming compartment is below a threshold value during the first ice making cycle, a control signal is generated in response thereto and during a second ice making period the valve is opened for a second period of time in response to generation of the control signal so that water advances into the ice forming compartment of said ice tray through the valve during said second ice making cycle for a period of time that is greater than the first period of time.
