Diagnostics show E8; condenser fan may not run; refrigerator may be warm and compressor very hot.

Safety first: Unplug the refrigerator before accessing the rear compartment. The compressor and condenser components can be hot.

Steps to resolve:

• Access the condenser area: Remove the lower rear access panel to expose the condenser fan and coils.
• Check for obstructions: Look for debris, pet hair, or packaging blocking the fan blades. Remove any obstructions carefully.
• Clean condenser coils: Use a coil brush and vacuum to clean dust from the coils. Improved airflow can reduce fan load.
• Test fan spin: With power off, spin the fan blade by hand. It should move freely. If stiff or noisy, the motor is failing.

Restore power and observe whether the fan runs when the compressor is on. If not, the fan motor or control board is defective. Replacing the condenser fan motor is a moderate repair; if you are not comfortable, contact a technician.
