Yu have a sticking sequencer that will have to be replaced.Give me a moment and I will get you a part number if you want to replace it yourself.

Expert:  airheatman replied 25 days ago.

Your furnace has two sequencers. I recommend replacing both because if one is bad, the other is likely to follow.

Part numbers are 42-23116-07 and 42-23116-09

You can get them from Amazon
