Possible Causes
Cooling fan running too slowly, obstructed airflow, failing fan motor bearings, main PCB fan speed monitoring fault
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker and allow the oven to cool.
- Check external ventilation: Ensure that cabinet cutouts and clearances meet LG Studio installation requirements and that vents are not blocked.
- Inspect cooling fan: From the rear, observe the fan (with power restored briefly) to see if it starts promptly and runs at a steady speed. Turn power OFF again before touching anything.
- Clean and clear: Remove dust, insulation, or debris from around the fan and air channels.
- Replace fan if sluggish: If the fan is slow to start, noisy, or wobbly, replace the cooling fan motor assembly.
- If fan is good but F95 persists: The main PCB may be misinterpreting fan speed feedback and may need replacement.
Warning: Operating the oven with inadequate cooling can damage internal components and pose a fire risk.
