Spoke to a nice gentleman that has exceptional service care. He called to make sure everything was good to go on my side and said to contact him if anything went wrong or I needed help.
Installed the circuit board myself (saving myself $1,400). Everything started fantastic except the rear orifices for the gas grate, on the right side, were rusted shut; that caused the flame sensor to shut down the furnace.
Took off the grate and wire brushed it, blew it off, re-installed, and everything operates beautifully. Save yourself the money and check for corrosion or faulty sensors. The picture attached (if it attached) is the old circuit board.
