Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off the ice maker before working around it. Unplug the refrigerator if removing covers or disconnecting wiring.
Steps to resolve:
- Reset ice maker: Turn the ice maker OFF for 30 seconds, then ON. Some models have a test button—press and hold per the service sheet to run a harvest test.
- Check ice box temperature: Ensure the ice compartment is near 0°F to 10°F (-18°C to -12°C). If warm, check for blocked vents or door not sealing.
- Inspect harness: Remove the ice maker cover and verify the sensor harness is fully seated and not pinched.
If E5 persists and the ice maker does not cycle during a test, the ice maker assembly or its thermistor is likely defective and should be replaced. A technician can confirm by measuring sensor resistance and running diagnostic tests.
