Hello, locate the flame sensor rod on the units wiring diagram glued to the inside of the blower access door. follow the wire to it on the furnace, all you will see is a white ceramic nipple near the fire box... remove it and clean the flame sensing rod with a scotch bright pot scruber pad.

Let me know how that goes, we can continue from there at no additional charge as needed
