Heatcraft eg-2 to Surelight 83m00


I am replacing my Heatcraft circuit board with a Lennox Surelight 83m00. The names of the connections don't match (even though HC is a Lennox company) could someone tell me which connectors from the HC to the Lennox connectors? Thanks.

Lennox Uhg80-40. I am not sure it is a direct replacement as I cannot find one for the Heatcraft. When I purchased the new board it was the replacement for the board that was supposed to be in the Uhg80.

see tables 1 and 2..........

there are not that many connections to make so if you need more detail let us know.....Hopefully you have not disconnected old control yet.

Joe, did you look at the link i posted it tells you what goes where from the old to the new. BTW, no wonder I couldn't find it, you gave me the wrong board number.

I appreciate your help, but I have both of these documents. The labels on the Heatcraft are not the same labels as the Lennox. THAT is my original question. Or, asked another way; what are the corresponding labels, HC to Lennox and vice versa. Thanks.

Take some clear pictures of both boards, post 'em and we'll be done with this very soon, I'd suspect.

correct. Heatcraft did not label their connectors/terminals with the same names as Lennox...can you translate the HC labels so they match the Lennox ones?
