Error code Er FF displayed, freezer section warm or not freezing properly, little or no airflow from freezer vents.

Safety first: Disconnect power at the wall outlet or breaker before servicing. Food may begin to thaw; plan accordingly.

Steps:

• 1. Confirm airflow issue: With the unit running (before unplugging), feel for airflow from freezer vents. Weak or no airflow supports a fan issue.
• 2. Access freezer evaporator fan: Empty the upper freezer shelves. Remove the rear interior panel (usually held by Phillips screws). Carefully pull the panel forward to expose the evaporator coil and fan assembly.
• 3. Check for frost/ice: Look for heavy frost or a solid ice block around the fan or coil. If present, you may have a defrost problem causing the fan to stall.
• 4. Clear ice safely: Unplug the fridge. Use towels to catch water. Use a hair dryer on low to melt ice around the fan and coil. Do not overheat plastic parts.
• 5. Inspect fan motor: Spin the fan blade by hand. It should rotate freely. If it binds, wobbles, or feels gritty, replace the fan motor.
• 6. Check wiring: Inspect the fan connector and harness for loose pins, corrosion, or broken wires. Reseat the connector.
• 7. Test motor electrically: With a multimeter, measure resistance across the motor terminals. An open circuit or very high resistance indicates a failed motor.
• 8. Replace evaporator fan motor: If defective, remove mounting screws, transfer the fan blade to the new motor, and reinstall. Ensure the blade is oriented correctly and not rubbing the shroud.
• 9. If fan and wiring are good: If the fan tests good but never receives voltage when the compressor runs, the main control board may be faulty and should be tested or replaced by a qualified technician.
