Furnace starts out great & then later not?
Two trips in a row now are furnace starts out great! Lots of heat & by morning when we wake it blowing cold. Can anyone help me fix this? Suppose to another cold night.

oldbeek, I have to agree with Suburban that you have restricted ducting causing the high limit switch to open. Mine does the same but I don't think mine cuts out at six cycles. Mine runs a long time with about 2 minutes burner on and 1 minute burner off. I have also added an additional duct but have not tested it yet. I have an OEM board not a Dinosaur.
To the OP, can you tell if the burner is cycling while the blower continues to run?
To be honest these last two post are much more technical than I understand?
Yet appreciate it, in time I 'll start understand your lingo. :)
