Fan Blade Wobble, Grinding Noise & Uneven Heat — A Loose or Missing Motor Nut Is Usually the Cause

When the convection fan motor nut loosens or goes missing, the fan blade shifts on the shaft — producing a grinding or rattling noise, disrupting airflow, and risking damage to the motor and oven cavity lining. This is the genuine OEM replacement nut (FAD33778501) sourced directly from LG. One small part, one fix.

Symptoms of a Failed Convection Fan Motor Nut

Rattling or grinding noise from the rear of the oven during convection mode
Fan blade visibly wobbling or loose on the motor shaft
Reduced, uneven, or absent convection airflow
Nut visibly missing, stripped, or cross-threaded
Oven not reaching temperature evenly despite heating element working

Part Details

OEM Part Number: FAD33778501
Brand: LG
Part Type: Convection Fan Motor Nut
Condition: New Genuine OEM

💡 Pro Tip — Inspect the Fan Blade While You're In There:
If the nut was loose long enough for the blade to wobble, check the blade for stress cracks, deformation, or scoring on the motor shaft. Replacing the blade and nut together eliminates a second service call and restores balanced airflow from day one.

Installation Notes

Skill Level: Beginner–Intermediate
Disconnect power to the range/oven before starting any repair
Allow the oven to cool completely before accessing the convection fan assembly
Tighten the nut securely — snug is sufficient, do not overtorque
Confirm the blade spins freely without contact after installation
