Display shows 21E; refrigerator fan noise may stop, and cooling in the fresh food section is poor.

Safety first: Unplug the refrigerator before removing interior panels.

Step 1 – Listen for fan operation:

• With doors closed for several minutes, open the refrigerator door and listen for the evaporator fan behind the rear panel.
• If you hear scraping or no fan noise, proceed to inspection.

Step 2 – Access the refrigerator evaporator fan:

• Remove food and shelves from the fresh food compartment.
• Remove screws securing the rear interior panel (evaporator cover) and gently pull it forward.
• Disconnect any fan or light connectors.

Step 3 – Inspect the fan:

• Check for heavy frost or ice around the fan; if present, defrost carefully with a hair dryer on low.
• Spin the fan blade by hand; it should move freely without resistance.
• Inspect the fan motor wiring harness and connector for damage or looseness.

Step 4 – Test/replace the fan motor:

• With the unit unplugged, disconnect the Refrigerator Evaporator Fan Motor connector.
• Check for continuity across the motor terminals with a multimeter.
• If open or shorted, replace the fan motor assembly.

Note: If a new fan does not run and 21E persists, the Main PCB may be defective and should be checked by a professional.
