You will need to pull the burner tray out and clean and blow out the burners. Then you will need to pull the orfaces from the gas manifold and clean each one and blow out the gas line. Then with a mirror you will need to check the fire brick inside the burner box. Then you will need to replace anything that is damaged. Good luck.
Testimonial: "thanks for the insight. I assume that I will have to disconnect the gas line and then reconnect afterward. Appreciate your information."

Thank you for posting your question here on Fixya.com.
Replacing the roll out switch is an easy do-it-yourself repair. Fixing the problem causing the roll out of the burner flames in the first place is a bit more of a pro job. Something is causing to much heat to roll out the the combustion chamber into the control area causing the switch to fail. You will continue to burn the link until the underlying problem is fixed.
