Hello my name is ***** ***** will be my pleasure to assist you. The first thing to do is go to the panel box and check your breakers for the house to be sure there is no blown or tripped breakers. If all that is good then go to the furnace and take the lower blower door off and locate the control board in the control board there is usually a 3 or 5 amp fuse pushed into spade terminals of the board.
