M Oglesby :

This is a lockout code.

M Oglesby :

This may be a flame sensor issue.

M Oglesby :

The flame sensor rod is a small thin steel rod that is straight or L shaped and is usually located near the igniter or in the path of the burners. Locate it, remove it, and clean it with a piece of emery cloth or sandpaper very good.
