An insulated icemaking compartment is provided in the fresh food compartment of a bottom mount refrigerator. The icemaking compartment may be integrally formed with the liner of the fresh food compartment, or alternatively, may be modular for installation anywhere in the fresh food compartment. A removable bin assembly with a front cover normally seals the icemaking compartment to maintain the temperature in the compartment. A cold air duct formed in the rear wall of the refrigerator supplies cold air from the freezer compartment to the icemaking compartment. A return air duct directs a portion of the air from the icemaking compartment back to the freezer compartment. An air vent in the icemaking compartment directs another portion of air into the fresh food compartment. A control system provides for controlling refrigerator functions in a manner that promotes energy efficiency.

1. A method of controlling operation of a refrigerator comprising: providing a refrigerator with a plurality of compartments, the refrigerator comprising: a compressor with an on state and an off state;a damper with an open state and a closed state;a defrost heater with an on state and an off state;an evaporator fan with an on state and an off state; andan ice compartment fan with an on state and an off state;controlling the temperature within the refrigerator compartments by the steps of: a. obtaining temperature readings from each of a fresh food compartment, a freezer compartment and an ice compartment in an upper corner of the fresh food compartment in an interior space of a cabinet of the refrigerator, wherein the ice compartment is disposed between the cabinet and a fresh food compartment liner associated with at least two walls of the fresh food compartment, and further wherein the ice compartment is not disposed on a fresh food compartment door;b. monitoring ambient temperature external of the space;c. communicating the temperature readings in electrical signals to an intelligent control;d. calculating with the intelligent control a temperature value for each of the fresh food compartment, the freezer compartment, and the ice compartment based on at least two of the ice compartment, fresh food compartment, freezer compartment, and ambient temperature readings; ande. changing the temperature within at least one of the plurality of compartments by changing the state of at least one of the compressor, the damper, the defrost heater, the evaporator, and the ice compartment based on at least one of the calculated temperature values. 2. The method of claim 1 wherein the at least two walls further comprises a top wall and one of two opposing sidewalls. 3. The method of claim 1 wherein the fresh food compartment is in an upper portion of the cabinet. 4. The method of claim 3 wherein the freezer compartment is below the fresh food compartment. 5. The method of claim 1 further comprising entering of a user-selected temperature set point for one or more of the ice, fresh food, and freezer compartments. 6. The method of claim 5 wherein the calculated temperature value is dependent on the user-selected temperature set point for a given ice, fresh food, or freezer compartment. 7. The method of claim 6 further comprising a cooling system operatively connected to and providing cooling to any of the fresh food, freezer, and ice compartments in response to electrical instructions from the intelligent control. 8. The method of claim 7 wherein the cooling system responds to the one or more calculated temperature values. 9. The method of claim 8 wherein a calculating temperature value is dependent on at least two temperature readings of two compartments. 10. The method of claim 8 wherein the cooling system response is dependent on at least one temperature reading and at least one user-selected temperature set point. 11. The method of claim 8 wherein at least one temperature reading and at least one user-selected temperature set point are used to control cooling in the refrigerator. 12. The method of claim 1 wherein cooling to a compartment is dependent on a temperature reading of one or more of the ice, fresh food, and freezer compartments and ambient temperature. 13. A method of operating a refrigerator comprising: a. providing a refrigerator cabinet with a fresh food compartment disposed within the cabinet, a freezer compartment disposed within the cabinet, an ice compartment disposed within the fresh food compartment, an electronic control system associated with the refrigerator;b. providing within the refrigerator: a. a compressor with an on state and an off state;b. a damper with an open state and a closed state;c. a defrost heater with an on state and an off state;d. an evaporator fan with an on state and an off state; ande. an ice compartment fan with an on state and an off state;c. installing an icemaking assembly through an opening in a front of a liner associated with the fresh food compartment;d. monitoring and controlling 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;e. calculating with the electronic control system a temperature value for each of the fresh food compartment, the freezer compartment, and the ice compartment based on the readings of at least two of the ice compartment, fresh food compartment, freezer compartment, and ambient temperature sensors;f. changing the state of at least one of the compressor, the damper, the defrost heater, the evaporator, and the ice compartment based on at least one of the calculated temperature values. 14. The method of claim 13 wherein the liner further comprises a notch configured to at least partially enclose the ice compartment. 15. The method of claim 13 wherein the freezer compartment is below the fresh food compartment. 16. The method of claim 13 further providing a user interface operatively connected to the electronic control system allowing manual entering of a user-selected temperature value for one or more of the ice, fresh food, and freezer compartments. 17. The method of claim 13 wherein the electronic control system calculated temperature value is compared to the user-selected temperature value for a given ice, fresh food, or freezer compartment. 18. A method of controlling operation of a refrigerator comprising: a. providing a refrigerator cabinet having a fresh food compartment liner substantially contoured to a portion of the refrigerator cabinet comprising a fresh food compartment and an ice compartment, the refrigerator further comprising compressor, damper, defrost heater, evaporator fan, and ice compartment fan each with an on state and an off state;b. obtaining temperature readings from each of the fresh food compartment, a freezer compartment and the ice compartment, wherein the ice compartment is disposed between the fresh food compartment liner and the refrigerator cabinet;c. monitoring ambient temperature external of the refrigerator;d. communicating the temperature readings in electrical signals to an intelligent control;e. calculating with the intelligent control a temperature value for each of the fresh food compartment, the freezer compartment, and the ice compartment based on at least two of the ice compartment, fresh food compartment, freezer compartment, and ambient temperature readings; andf. controlling the temperature within fresh food compartment and the ice compartment by changing the state of at least one of the compressor, damper, defrost heater, evaporator fan, and ice compartment fan based on at least one of the calculated temperature values. 19. The method of claim 18 wherein the ice compartment is not disposed on a door associated with the refrigerator cabinet. 20. The method of claim 19 further providing a user interface operatively connected to the intelligent control wherein the user interface comprises a display control.
