To repair a GE icemaker that fails to create ice or receive water, check if the icemaker has the correct water pressure, replace the self-tapping saddle valve or remove any stuck cubes. GE recommends replacing the icemaker if it is jammed.
The appropriate water pressure for a GE icemaker is at least 40 pounds per square inch. Incorrect water pressure may cause an icemaker to produce three to five cubes only instead of the typical seven to eight cubes, since the machine is not completely filled with water. Change the self-tapping saddle valve, if there's any, as it is possibly not creating an adequate opening for water to enter. Choose a saddle valve that requires drilling a 1/4-inch hole in the pipe.
Check if the feeler arm’s movement is hampered by ice cubes. Cycle the feeler arm a few times to fix the blockage temporarily. If an ice cube is stuck on the mold, turn off the machine before getting rid of the obstruction. Turn the icemaker on, and test if it is working properly.
Another possible reason an icemaker doesn’t produce ice is a malfunctioning heater that stays on for a long period. Touch the icemaker mold cautiously to find out if the heater is turned on. If the mold feels hot, the icemaker is likely jammed and requires replacement.
