Refrigerator displays F9; ice maker may not function and freezer temperature may be unstable.

Safety: Disconnect power and turn off the water supply before servicing the ice maker.

F9 is associated with the ice system or its temperature sensing.

• Inspect ice compartment: Open the ice compartment and check for large clumps of ice, jammed cubes, or frost buildup around the ice maker.
• Clear jams: Remove the ice bin and clear any stuck ice from the ejector blades or rake. Do not use metal tools that can damage plastic parts.
• Check ice sensor: Locate the ice compartment thermistor or sensor (often near the ice bin). Ensure it is not covered in heavy frost and is properly mounted.
• Defrost if necessary: If the ice area is heavily frosted, unplug the unit and allow it to defrost fully. Dry the compartment before restarting.
• Inspect wiring: Examine the harness from the ice maker to the cabinet for damage or loose connectors. Reseat connectors firmly.
• Test operation: Restore power and water, then initiate an ice maker test cycle if your model supports it (refer to user manual). If F9 returns, the sensor or ice module may need replacement.
• Component replacement: Replace the ice compartment thermistor or complete ice maker assembly if they fail continuity or functional tests. Complex diagnostics may require a technician.
