We claim: 1. A refrigerator comprising: a cabinet defining a freezer compartment maintained at a temperature below 0째 C. and a refrigerator compartment maintained at a temperature above 0째 C. located above the freezer compartment; an insulated refrigerator door moveably mounted to the cabinet for selectively closing the refrigerator compartment; a refrigeration system for cooling the freezer compartment and the refrigerator compartment; an ice maker module mounted in the refrigerator compartment comprising an insulated housing enclosing an automatic ice maker and an ice cube storage bin; an ice dispenser located on the refrigerator door; and an ice cube dispensing outlet located in the refrigerator door; wherein the ice cube storage bin comprises a drawer movably mounted in the ice maker module and the ice maker module and ice cube storage bin are continuously maintained at a temperature below 0째 C. for forming and storing ice cubes. 2. The refrigerator according to claim 1, wherein the ice dispenser is located on the refrigerator door opposite the ice cube storage bin. 3. The refrigerator according to claim 1, wherein the ice maker module includes a first portion in which the ice maker is located and a second portion comprising the ice cube storage bin. 4. The refrigerator according to claim 3, wherein the second portion of the ice maker module comprises a drawer including an auger for moving ice cubes and the drawer comprises a wall having an opening for dispensing ice pieces and a movable door for closing the opening. 5. The refrigerator according to claim 4, wherein the ice maker module further comprises an operator for the movable door and a control for activating the operator when the auger is operated so that ice cubes moved toward the opening in the drawer can exit the drawer and enter the ice dispenser. 6. The refrigerator according to claim 4, wherein the opening in the drawer is in the bottom wall and the movable door is pivotally mounted to the bottom of the drawer to close the opening, and wherein the movable door is resiliently biased to close the opening so that when the auger is operated ice cubes moved toward the opening open the movable door and exit the drawer. 7. The refrigerator according to claim 1, wherein the refrigeration system includes an ice maker evaporator positioned in the ice maker module and arranged to maintain the ice maker module below 0째 C. 8. The refrigerator according to claim 1, further including at least one air duct leading to the ice maker module from a source of below 0째 C. air. 9. The refrigerator according to claim 8, wherein the refrigeration system includes an evaporator compartment and the at least one air duct connects the ice maker module to the evaporator compartment. 10. The refrigerator according to claim 4, wherein the drawer is positioned in the refrigerator compartment adjacent the ice dispenser wherein ice cubes dispensed from the opening in the drawer are received in the ice dispenser. 11. An ice maker and dispenser for a bottom freezer refrigerator having a freezer compartment maintained at a temperature below 0째 C.; a refrigerator compartment maintained at a temperature above 0째 C. positioned above the freezer compartment; an insulated refrigerator compartment door; and a refrigeration system for cooling the freezer compartment and the refrigerator compartment comprising: an insulated module maintained at a temperature below 0째 C. mounted inside the refrigerator compartment; an ice maker and an ice cube storage bin in the insulated module; a water supply for the ice maker; and an ice dispenser positioned on the refrigerator door to receive ice cubes from the ice cube storage bin and dispense ice cubes from the face of the refrigerator door wherein the insulated module includes a first portion in which the ice maker is located, a second portion comprising the ice cube storage bin having an auger for moving ice cubes, and a wall having an opening for dispensing ice pieces and a movable door closing the opening. 12. The ice maker and dispenser of claim 11, wherein the insulated module further comprises a drive mechanism for the auger, an operator for the movable door and a control for the drive mechanism and the door operator, wherein the movable door operator is activated when the auger is operated so that ice cubes moved toward the opening in the insulated module can exit the insulated module and enter the ice dispenser. 13. The ice maker and dispenser according to claim 12, wherein the opening is in the bottom wall of the second portion and the movable door is pivotally mounted to the bottom wall to selectively close the opening. 14. The ice maker and dispenser according to claim 13, wherein the door operator is a solenoid arranged to pivot the movable door downwardly when the solenoid is activated. 15. The ice maker and dispenser according to claim 13, wherein the door operator is a motor arranged to pivot the movable door downwardly when the motor is activated. 16. The ice maker and dispenser of claim 11, wherein the opening is in the bottom wall of the second portion and the movable door is rotatably mounted to the bottom wall and resiliently biased close the opening. 17. The ice maker and dispenser of claim 16, wherein the movable door is spring biased to the closed position. 18. The ice maker and dispenser of claim 17, wherein the spring bias for the movable door is sufficient to hold the movable door closed when no ice cubes are resting on the movable door. 19. The ice maker and dispenser of claim 18, wherein the weight of at least one ice cube is sufficient to open the movable door and allow the ice cube to fall out of the second portion and enter the ice dispenser when the auger is operated. 20. The ice maker and dispenser according to claim 14, wherein the refrigeration system includes an ice maker evaporator positioned in the insulated module and arranged to maintain the insulated module below 0째 C. 21. The ice maker and dispenser of claim 11, further including supply and return air ducts leading to the insulated module from a source of below 0째 C. air to maintain the insulated module below 0째 C. 22. The ice maker and dispenser of claim 21, wherein the refrigeration system includes an evaporator compartment and the supply and return air ducts connect the insulated module to the evaporator compartment.
