I have a Goodman GDT furnace that the fan was running all the time called repair man he said the relay was stuck needed to order a new board he suggested online it woulld be cheaper he advised that when i got it in just turn the power off to the furnace and replace the board one wire at a time secure the board back in the furnace and turn the power back on and it would be fine ok we did all that i am sure i got wire for wire but unable to find a diagram to verify but now when i turn the power on it just kicks the breaker so i put the old one back in that had the stuck relay and it also kicks the breaker what next thanks
Thanks and God Bless

If you did not get the wiring correct you may have blown the transformer or something else. Some Goodman replacement boards are retrofits and may require some wiring changes. Not every job is DIY friendly. Sounds like you need a tech to find out what went wrong.
