Hi, glad to find some help, I found your site by accident,or my good fortune! I have a concord 80 , the thermostat clicks and the blower comes on but the furnace does not light,all help appreciated

Does your furnace have a glow ignition or spark? There is a wiring diagram on the inside of the blower door. If you have an electric meter you can check the control circuits to find the part that is preventing the furnace from operating.

My concord 80 has a sparker not a pilot
