LG oven error F9 – Oven not heating properly
Is your LG oven failing to reach the right temperature or taking too long to cook food? The F9 error indicates an oven heating issue, which can result in uneven cooking.
Common causes:
- Faulty temperature sensor
A damaged sensor may send incorrect temperature readings to the control board.
- Broken bake element
If the heating element fails, the oven won’t generate enough heat.
- Defective oven control board
A malfunctioning board may not regulate heating cycles properly.
- Loose or burned wiring
Damaged wires can disrupt power flow to heating components.
How to fix it:
- Test the temperature sensor
Use a multimeter to check resistance. Replace if defective.
- Inspect the bake element
Look for visible burns or cracks and replace if needed.
- Check wiring connections
Secure loose wires and inspect for damage.
- Reset the oven
Unplug for 5 minutes and restart to see if the error clears.

Regularly cleaning your oven and inspecting components can prevent heating issues.
