The refrigerator displays Er rF, the fresh food section is warm, and there is weak or no airflow from the refrigerator vents.

Safety first: Unplug the refrigerator before removing any interior panels. Use caution around sharp metal edges.

Procedure:

• 1. Verify symptom: With the unit running (before unplugging it), open the refrigerator door and feel for airflow from the rear vents. Weak or no airflow indicates a fan or airflow issue.
• 2. Remove shelves and drawers: Take out the lower shelves and crisper drawers to access the rear panel of the fresh food compartment.
• 3. Remove rear panel: Unplug the unit. Remove the screws securing the rear interior panel and gently pull it forward to expose the evaporator coil and fan.
• 4. Inspect for frost buildup: Look for heavy frost or ice covering the coil or fan. If present, you may have a defrost system failure; clear the ice with a hair dryer on a low setting and use towels to catch the water.
• 5. Check fan operation: Spin the fan blade by hand. It should move freely. Any stiffness, scraping sounds, or looseness suggests a faulty motor or a misaligned blade.
• 6. Inspect wiring and connector: Ensure the fan connector is fully seated and wires are not pinched or broken.
• 7. Test motor resistance: Use a multimeter to measure the resistance across the fan motor terminals. Compare the reading to the specifications; an open circuit (OL) indicates a failed motor.
• 8. Replace fan motor if faulty: Remove the mounting screws, transfer the fan blade to the new motor, and reinstall. Make sure the blade does not contact the shroud.
• 9. If fan is good but code persists: The main control board may not be powering the fan. Further diagnosis or board replacement by a professional is recommended.
