Hello, my Concord 80 turn the sparker on, then the burners turns on like supossed to, the problem begins when the sparker shuts off, aparently the burners shuts off at the same time the sparker does. As a result the blower never turns on.

Clean the flame senser

Thanks very much, I cleaned it and now is working like new.

Thanks again you saved me.

Glad it worked out. Take care, Happy new years
