Control logic for compact ice making system

A refrigerator comprising:

• a fresh food compartment;
• a freezer compartment;
• an ice compartment disposed in the fresh food compartment;
• an ice maker assembly disposed in the ice compartment, the ice maker assembly including an ice maker tray/evaporator having an evaporator cooling tube which is in direct contact with an ice maker tray portion;
• a tray temperature sensor for sensing a temperature of the ice maker tray/evaporator;
• an ice bucket for storing ice, the ice bucket being disposed in the ice compartment;
• and
• a controller configured to control ice making, ice harvesting, and ice maintenance based on the temperature sensed by the tray temperature sensor,
• wherein the tray temperature sensor is the only temperature sensor used to control ice making, ice harvesting, and ice maintenance,
• wherein the ice maker assembly and the ice bucket are arranged side-by-side in a horizontal direction within the ice compartment, and
• wherein no portion of the ice bucket is located below the ice maker assembly when the ice maker assembly is projected downward in a vertical height direction.
