LG Oven Error Code F27 — Cooling Fan Stalled During Self-Clean
What this means
The F27 error code indicates the oven's cooling fan has stalled during a self-clean cycle. The cooling fan protects the oven's electronic components and surrounding cabinetry from excessive heat during the high-temperature self-clean process. If the fan stalls, the oven aborts the self-clean to prevent heat damage.
Step-by-step fix
2 stepsReset the oven
Turn off the circuit breaker for 30 seconds, then restore power. Allow the oven to cool completely before attempting another cycle.
Check for obstructions
Inspect the cooling fan area (usually behind a vent panel at the top or back of the oven) for debris or objects blocking the fan blade.
When to call a professional
If the cooling fan motor has failed, professional replacement is recommended, especially since the self-clean feature cannot be used safely without it.
