LG Refrigerator Airflow Problem or Frost Buildup? Fan Grille Assembly AEB73764526 – Fix Uneven Cooling Fast

If your LG refrigerator has uneven cooling, frost buildup on the back wall, or poor airflow between compartments, the evaporator fan grille assembly is a common cause. In most LG French door and side-by-side refrigerators, the fan grille assembly directs and controls airflow from the evaporator fan across the cooling coils and into the fresh food and freezer sections. When it cracks, warps, or breaks, airflow becomes uneven, cold spots and warm spots develop, and frost can accumulate on the evaporator. ⚡ Common failure point in LG-built French door refrigerators. Part AEB73764526 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 freezer section)
• ✔ Defrost system is functioning — no heavy ice buildup on coils
• ✔ Existing grille is visibly cracked, broken, or missing sections
• ✔ ONLY problem is uneven airflow, inconsistent temperatures, or poor cold air distribution

🔧 Common Symptoms

• Fresh food section warmer than set temperature despite freezer being cold
• Frost or ice buildup on the back wall of the freezer compartment
• Uneven temperatures — some shelves cold, others warm
• Visible cracks or broken tabs on the existing fan grille
• Er FF or airflow-related error code on the display panel
• Increased compressor run time as unit struggles to maintain temperature

✔ 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.
