GE GTS18GTHWW 17.5 cu ft Top Freezer Refrigerator White MECH-ICEMAKER Error Fix: Ice Maker Not Producing Ice

Error code MECH-ICEMAKER on the GE GTS18GTHWW 17.5 cu ft Top Freezer Refrigerator White means: Ice Maker Not Producing Ice. The ice maker is not producing ice cubes — check that the ice maker is turned on (arm down or switch on, depending on model); ensure the water supply valve behind the refrigerator is fully open; the water fill tube at the back of the freezer can freeze shut — use a hair dryer to gently thaw it; water pressure must be at least 20 PSI for the inlet valve to operate; the water inlet valve solenoid can also fail; finally, the ice maker module itself (motor assembly) can wear out; increase freezer temperature if set below -5°F as extreme cold can slow ice production
