For the ice maker on a GE Cafe refrigerator to function, the ice maker must be turned on, the refrigerator must plugged in and the water line must be connected and free from kinks or bends. The wire shut-off arm should also be free of obstructions.
The power switch for GE Cafe refrigerator ice maker is located on the side of the ice maker bin and must be in the "on" position for the unit to function. A glowing green light indicates that the unit is powered. It may take up to 24 hours for the refrigerator to become cold enough to make ice. If the refrigerator is too empty, or the ice maker is used infrequently, the ice may clump. An incorrectly placed ice bin may also cause ice to not dispense properly.
Water pressure must be between 40 and 120 psi for the ice maker to function. Water enters the refrigerator via an inlet valve on the back of the refrigerator. Bends or twists in the line may prevent adequate water flow. Clogged water filters need replacement, as they may also reduce water pressure. Correct water pressure may be verified by dispensing water into a receptacle for 20 seconds. If there is less than 13.5 ounces of water dispensed, the water pressure is insufficient.
