I have a 1982 Bryant 397HAW360100 model furnace. It has been acting funny and seems to be getting continually worse. It does run and does heat, but the issues I'm having is that the burners continually kick on and off. Generally now, the burners fire for about 2 seconds then shut off about 2-3 times before the blower even comes on and then shut off at least once during cycle. I have replaced pilot assembly recently and replaced main borad 2 years ago. Does anybody have any ideas about this?

On start up,watch the burners close up, do any of the burners seem to have flame rollout? The flame in one burner have a different color flame or flame is much higher than the rest?


Let us know,
