If your GE refrigerator is running fine but the ice maker is not working, it could be a number of different things causing the problem, depending on the diagnosis. Some GE ice maker troubleshooting tips will allow you to determine what is causing the problem and maybe even offer some ideas on how to fix it.
Ice Maker Will Not Make Ice
If your GE ice maker will not produce ice, check that it is turned on. The shutoff arm is near the top of the bin. If it is raised, the ice maker is off. If there is water in the ice bin but no ice, check that water is getting to the water valve. If it is, then you could have a broken fill valve or the control module will not activate the water valve. Check behind the refrigerator for a crinkled water supply line. Change the water filter if you have not changed it recently. Check that the inlet tube, which directs water to the ice cube tray, is not frozen. Thaw it with a hair dryer, but do not overheat, or the plastic will melt. Adjust the thermometer to a warmer setting. Make sure water is not dripping from the inlet tube. If it keeps dripping, replace the control valve. If the ice maker assembly has any broken parts, they will have to be replaced.
Ice Maker Will Not Release Ice
If your GE ice maker will not release ice, it could be that the ice maker module is not advancing. The small heating element that preheats the ice cubes before sending them to the ice bin seldom fails. It is usually the thermostat or control module causing the problem. If the mold thermostat on the ice maker will not switch on the heater, check that it is properly cycling. Check that the water inlet valve is opening properly, and if not, then replace it.
Ice Maker Leaks or Overfills
If your GE ice maker leaks or overfills, check that the ice maker and refrigerator are level. If there is a small leak, check for a crinkled water line. If there is a large leak, it is caused by a component failure.
Ice Maker Makes the Cubes Too Small
If your GE ice maker is making ice but the cubes are too small, check the adjustment knob near the ice maker's side. It could be that the water line behind the refrigerator is clogged. Check that there is good water flow. If there is a poor flow of water, clean, repair or replace the shut-off valve or tubing that supplies the water.
Ice Has a Bad Taste or Odor
If your GE ice maker produces ice with a bad taste or odor, it could be from flavor transfer or food odor coming from old food in the freezer or the refrigerator compartment. Wash all the interior surfaces of the refrigerator and freezer with a vinegar and water solution, and then dry them. Dump out all the ice in the bin and begin fresh.
