Safety: Disconnect power before accessing the fan. Moving fan blades can cause injury.

Steps:

Listen for the fan: With the doors closed and the unit powered (briefly), you should normally hear a soft fan noise from the freezer or rear of the fridge. If silent or grinding, suspect the fan.
Access the evaporator fan: Remove shelves and the rear interior panel in the freezer (or refrigerator, depending on model) to expose the fan assembly.
Check for ice buildup: If the fan is encased in ice, defrost the area completely by unplugging the unit and leaving doors open. Do not chip ice with sharp tools.
Inspect the fan: Spin the blades by hand; they should move freely without scraping. Check the wiring connector for burns or looseness.
Test the motor: With the fan disconnected and the unit unplugged, measure motor winding resistance. An open circuit indicates a failed motor.
Replace the fan motor: Install a Sharp-compatible evaporator fan motor assembly, ensuring correct orientation and secure mounting.

If E8 persists with a new fan and good wiring, the main control board’s fan driver may be defective and require replacement.

Display shows E8 and the fan noise may be abnormal or airflow is weak in one compartment.
