Moderate
Address soon - your appliance may not work properly
Also displayed as: F and R blink (ice maker function error — item 26 in self-diagnosis list)
What This Means
Failed ice maker assembly (gear motor, mold heater, or harvest switch); Broken wiring harness to ice maker; Water valve not supplying water (separate fault); Ice maker sensor error (see separate code)
What actually causes this:
The ice maker assembly itself — the motor, the ejector arm, or the harvest mechanism — has failed.
First Thing to Check
Press the Ice Maker button on the panel to confirm the ice maker is switched ON (Ice Maker On light should be lit).
Parts Involved
How to Fix
- 1
Press the Ice Maker test button on the ice maker assembly and hold for more than 1.5 seconds — ice maker should rotate through harvest cycle
- 2
If no rotation, check MICOM pin 18 input voltage (should change 5V/0V during motor rotation)
- 3
Check if water is supplied after a harvest cycle — if not, inspect water valve
- 4
If no mechanical response, check wire connections to ice maker and CN90 connector
- 5
Replace ice maker KIT if all wiring and PCB outputs are normal
