Nice cheap replacement for my failed expensive board. Fixed my problem and my furnace is back up and running. I took a picture of the old board wired in before removing it. Then just matched the wires back up to this new board. Made it a quick and easy job.

Our furnace quit and the outside temp was 24 degrees! We were able to order this for half the price of others and got it delivered overnight! Works like a charm and furnace is back up and running, we are truly grateful!

Perfect replacement for ST9120C2010 that burned up and died. I had that one out and this one in in about 15 minutes time and now have my furnace blower back up and running.I highly recommend this as a pop-in replacement for that specific blower circuit board.
