My 20+ old furnace fan/blower will not work. The furnace starts and heats up just fine but the main fan/blower will not come on. I have trouble shooted the circuit per my manual and have no 110V power coming out of the control board.
Do I need a new control board or is there another switch in the circuit that is keeping the fan from running?
