Possible Causes
Worn convection fan motor bearings, worn cooling fan motor bearings, misaligned fan shaft
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before touching any internal parts.
- Determine which fan: If the noise occurs only during convection modes, suspect the convection fan. If it occurs during cool-down, suspect the cooling fan.
- Access the noisy fan: Remove the appropriate interior or rear panel to reach the fan motor.
- Spin test: Rotate the fan by hand. A rough or squeaky feel confirms bearing wear.
- Replace motor: Replace the entire fan motor assembly; lubrication is usually a temporary fix and not recommended inside ovens.
Note: Use only LG-approved replacement motors for LG Studio ovens.
