F8 appears and the refrigerator may not cool properly, with fans not running or running erratically.

Safety: Disconnect power before accessing internal fan assemblies. Fan blades can start unexpectedly when powered.

How to proceed:

• 1. Listen for fan operation: With doors closed for several minutes, you should normally hear a gentle fan noise. If silent, suspect the evaporator fan.
• 2. Access evaporator fan: Remove freezer drawers and the rear interior panel to expose the evaporator and fan housing.
• 3. Check for ice buildup: If the fan is encased in ice, fully defrost the unit. Ice can stall the fan and trigger F8. Ensure the defrost system is working (see defrost-related faults).
• 4. Spin the fan by hand: With power off, gently rotate the fan blades. If stiff or seized, replace the fan motor assembly.
• 5. Electrical test: Disconnect the fan connector and measure resistance across the motor terminals. An open circuit indicates a failed motor. Also inspect the harness for damage.
• 6. Control board: If the fan motor tests good and receives no voltage when it should be running, the main control board may be at fault.

After replacement: Ensure the fan shroud and wiring are correctly reinstalled to avoid noise and vibration.
