Control boards are different with every model but basically are small computers that look like these Amana Furnace Model GUVA090BX50 Control Board (http://www.myhvacparts.com/Catalogue/Printed%20Circuit%20Boards/Amana%202030006-S%20Control%20Board.htm) Yes your stat connects to the control board usually 4-5 colored wires
