Yeah, it does have the troubleshooting blinking light on the board. The clueless HVAC tech told me that the blinking light is normal. I think the HVAC tech just played games with me and actually has no idea what the hell he’s doing. Well, I’m selling my house this year anyways, so I think I’ll leave it the way it is and advise or disclose to the Buyers about this situation.

David if I was sitting in front of your furnace instead of this dumb computer from what you stated that it only kicks off during an extended run time trying to catch up I would first be looking at a limit switch as the guilty party or possibly the roll out switch.
The blinking lights will normally tell you what device failed if you can decipher the codes but you have to observe the configuration of blinking lights before you kill the power to the unit and reset the board.
