I am replacing a Goodman GMNTE 120-5 control board (11 years

Customer Question

I am replacing a Goodman GMNTE 120-5 control board (11 years old) with a 50V51-290-01 White-Rodgers/Emerson board. All connectors seem compatible except the blade terminals have different "E numbers" and slightly different nomenclature. Is there a chart to show proper connection? The older board has Emerson markings 4562-RevB and the newer board is marked Emerson 4893D. This board description claimed while a revised version it was compatible with the older one.
Any help would be appreciated: W. Good

win, Well if you could send a picture the old one and new one I can help you with wiring it up, Rev usually is just a revision wether they changed something small or big on the board, I crossed the board and it seems to be the match

Since the nomenclature and terminal ID's are different I was hoping for a wiring diagram cross reference or schematic depiction, anything else is just guess work and as a former circuit designer I can guess as well as anyone. This has not been any help. Please cancel this service for me.

I can guarentee its not guess work, ill request a cancellation for you but remember we are experts in this trade/field and were not sitting there with you, so sometimes having a picture of what were actually looking at really helps.
