OK... embarrassment time. Everything is working fine. When I got home the other day it was COLD inside, windows left open and heat OFF. I switched on the heat and showered. It felt HOT when I came out, blower was still running but place was at set point. I panicked because I had worked on the furnace I felt like maybe something was wrong. I was tired and didn't feel like messing with it. The next day after posting here I switched the heat on and OBSERVED. Yes, the blower runs after reaching set point, which makes sense. Everything has been on AUTO and working fine. Thanks everyone.
