Need help swapping out Goodman control board.

I am having a problem swapping out the new replacement board I received for my furnace.

The new board is configured differently from the old, obsolete one, and I am not certain where a couple of the new connections go.

Here is a shot of the old board and and one showing the existing wiring connections of the existing board. There are only five connections to be made here, (3 in the neutral section; 2 in the hot). but the labeling of the circuits does not match. See third picture.

All help appreciated!

I screwed up...

This is an actual photo of the new board. The one I grabbed off the net is different.

I've also added a close up of the top of this new board. The problem is that the new board neutrals are not labelled like the old board.

Sorry for the confusion - it's been a long day.

On the last photo you posted there are three neutral terminals at the top right side. That is where your three neutral wires will connect. These three terminals are all tied together. Turn the board over and you should be able to see where they are connected.

Your other wires should be connected in the 120VAC section:

Thanks, guys...

Just wanted to say thanks for the help.

I installed the new board and the furnace is working again.

Quoted replacement cost by the company: $725.00 plus tax.

Actual cost of new board: Less than $200.00.

The satisfaction of saving approx. $600.00 and doing it myself: PRICELESS!

That board looks like it came out of a gmv furnace - should have a 10 year warranty.
