An ice maker is essentially an appliance within an appliance, and its functionality depends on the refrigerator to provide cold and electricity. This guide will help you troubleshoot, test, and repair common ice maker problems.
How an Ice Maker Works
An ice maker works by filling an ice mold with water from the household supply line. Once the water freezes, the ice maker ejects the ice cubes into the ice bin. This process is controlled by several components, including a control module, thermostat, and various switches.
Troubleshooting Ice Maker Problems
Use the following chart to identify and troubleshoot common ice maker issues:
- Ice Maker Not Making Ice:
- Possible Causes: No water supply, faulty water inlet valve, clogged supply line, defective thermostat, or faulty control module.
- Solutions: Check the water supply, test and replace the water inlet valve, flush the supply line, test the thermostat, and inspect the control module.
- Ice Maker Not Ejecting Ice:
- Possible Causes: Faulty ejector motor, faulty ejector gear, or defective ice mold heater.
- Solutions: Test and replace the ejector motor, inspect and replace the ejector gear, and test the ice mold heater.
- Ice Maker Not Filling with Water:
- Possible Causes: Faulty water inlet valve, defective inlet switch, or clogged fill tube.
- Solutions: Test and replace the water inlet valve, test and replace the inlet switch, and inspect and flush the fill tube.
- Ice Maker Overflowing:
- Possible Causes: Faulty water inlet valve or defective inlet switch.
- Solutions: Test and replace the water inlet valve and inlet switch.
