Hello, I just bought a new control board for my carrier furnace and did the replacement but now I have an error, so my question is would you reverse line polarity first or control leads ? I am afraid of ruining the board if I do the wrong one first, but I have read a lot of questions and most of them say to reverse the control voltage leads ? Also the replacement instructions were very detailed and easy to do, and the wires are in the spots it called for so this is why I'm unsure to switch wiring ? And my old board #HK42FZ009 and my new board is an ICM282A thank's for your help
