The inducer motor comes on after awhile the igniter will glow but not right away. then the flame sensor detects the flame and the gas value opens and the burners ignite. Nthey burn for 10 minutes or so then the flame goes out. But instead of the blower running fopr a few minutes it does not shut down. Instead it continues to run then after 6 bor 7 minutes the igniter re-ignites the burners and the cycle continues with the blower motor still on. "the 5 flashes indicates that there is a false flame indicated or the gas value is sticking. Please explain how I continue to check what is wrong? Is my flame sensor not recognizing that the flame went out so the sequence stops at this point? Replace or clean again? Thanks mike
