What causes LG oven error code F-19?
Error code F-19 is caused by convection fan motor problems including motor failure, blocked fan blades, loose electrical connections, or debris interfering with fan operation.

You may be able to use regular baking modes, but convection cooking will not work properly. The error indicates the convection system is malfunctioning, which affects even heat distribution.
How much does it cost to fix F-19 error on LG oven?
