Freezer (on combo units) shows rF; fresh food fan may be noisy or not running, affecting freezer airflow balance.

Safety: Disconnect power before removing interior panels.

rF indicates the refrigerator section fan is not operating correctly, which can indirectly affect freezer performance.

• Access fresh food fan: Remove shelves and the rear panel in the refrigerator compartment to expose the fan.
• Check for ice: Look for ice blocking the fan. Fully defrost if necessary.
• Spin and inspect: Manually spin the fan. Replace the motor if it is seized, noisy, or loose on the shaft.
• Check wiring: Ensure the fan connector is secure and wires are intact.
• Test operation: After reassembly, restore power and listen for the fan when doors are closed (or door switch held). If it does not run with proper voltage, replace the fan motor.

If the fan is good but rF persists, the main PCB may be defective and should be diagnosed by a professional.
