LG Refrigerator Uneven Cooling or Frost Buildup? Fan Grille Assembly AEB73764516 – Fix Airflow Fast

If your LG French door refrigerator has uneven temperatures, frost accumulating on the freezer back wall, or the fresh food section is warmer than expected, the evaporator fan grille assembly is a common cause. In most LG LFXS series refrigerators, the fan grille assembly directs and channels cold air from the evaporator fan across the coils and into both the freezer and fresh food compartments. When it cracks, warps, or breaks — typically from ice expansion or physical impact during cleaning — airflow becomes uneven, temperatures fluctuate, and the compressor runs longer to compensate. ⚡ Common failure point in LG-built French door refrigerators. Part AEB73764516 is the genuine OEM replacement fan grille assembly that restores proper airflow distribution — no modifications required.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Refrigerator has power and the compressor is running
• ✔ Evaporator fan motor is confirmed working — audible hum from the freezer section
• ✔ Defrost system is functioning — no heavy ice buildup on the evaporator coils themselves
• ✔ Existing fan grille is visibly cracked, broken, or has missing clip tabs
• ✔ ONLY problem is uneven airflow, inconsistent temperatures, or poor cold air distribution between compartments

🔧 Common Symptoms

• Fresh food section warmer than set temperature while freezer stays cold — most common, what customers search
• Frost or ice buildup on the back wall of the freezer compartment
• Uneven temperatures across shelves — some areas cold, others warm
• Visible cracks, broken tabs, or missing sections on the existing fan grille
• Er FF or airflow-related error code displayed on the control panel
• Compressor running continuously as the unit struggles to maintain set temperatures

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this fan grille assembly restores even airflow and consistent temperatures immediately.
