Hi I'm Brian and I'm here to help!

As best I can tell the part number you need for the replacement control board on your furnace is an 80M27 which replaces old part number 20549901. Click Here for a picture of the 80M27 board and tell me if this board will fit your furnace please. If so, I will find the part for you at the best possible cost online.
