Electronic control system for insulated ice compartment for bottom mount refrigerator

A refrigerator, comprising:

• a refrigerator cabinet;
• a fresh food compartment disposed within the cabinet;
• a freezer compartment disposed within the cabinet;
• an ice compartment disposed within the cabinet;
• an electronic control system associated with the refrigerator and adapted to monitor and control temperature in the fresh food compartment, the freezer compartment and the ice compartment;
• an ice compartment temperature sensor associated with the ice compartment and electrically connected to the electronic control system;
• a fresh food compartment temperature sensor associated with the fresh food compartment and electrically connected to the electronic control system;
• a freezer compartment temperature sensor associated with the freezer compartment and electrically connected to the electronic control system;
• and
• an ambient temperature sensor electrically connected to the electronic control system.

A refrigerator, comprising:

• a refrigerator cabinet;
• a fresh food compartment disposed within the cabinet;
• a freezer compartment disposed within the cabinet;
• an ice compartment disposed within the cabinet;
• an electronic control system associated with the refrigerator and adapted to monitor and control temperature in the fresh food compartment, the freezer compartment and the ice compartment;
• a variable speed evaporator fan;
• and
• a variable speed evaporator fan output from the control system;
• and
• wherein the control system is adapted to set the van able speed evaporator fan at a first rate when the freezer is determined to require cooling and a second rate when the freezer is determined not to require cooling and the fresh food compartment is determined to require cooling, the second rate being lower than the first rate.

A refrigerator, comprising:

• a refrigerator cabinet;
• a fresh food compartment disposed within the cabinet;
• a freezer compartment disposed within the cabinet;
• an ice compartment disposed within the cabinet;
• an electronic control system associated with the refrigerator and adapted to monitor and control temperature in the fresh food compartment, the freezer compartment and the ice compartment;
• a variable speed evaporator fan;
• a variable speed evaporator fan output from the control system;
• and
