Refrigerator Ice Maker Not Working? Here’s What to Check

Posted on: November 15, 2016

If your ice maker has stopped making ice, here are some things to check:

  1. Check the Water Supply Line and Valve. The water supply line runs from the ice maker to a valve located behind the freezer, under the sink, or in the plumbing lines below refrigerator. Check that the valve is open enough to supply enough water. In most cases, it is recommended that the line be opened just enough to provide water pressure to fill the line. Check the line for pinches or kinks that could be obstructing flow.
  2. Check the shutoff arm. The arm should be in the down (on) position when making ice, and raised (in the off position) when the ice maker is filled.
  3. Check the Freezer Temperature. The freezer should be around 5 degrees (F) and the refrigerator around 36 degrees (F). The temperature controls can be found inside the freezer or refrigerator. To ensure the temperature is accurate, place a container of alcohol or cooking oil with a cooking thermometer inside the freezer and let it sit for about 2 hours. Because the oil or alcohol will not freeze, it will allow for an accurate measurement.

If none of the above items work, and you have confirmed that water is reaching the unit, it may a malfunction of one of the ice maker itself. Test the following parts for proper operation.

  • Ejector gear
  • Ejector motor
  • Ice mold heater
  • Holding switch
  • Thermostat
  • Inlet Valve
