Than its going to be in your heat coil/ valves and your flame sensor. The flame sensor is a rectangle box on the flame tube. Your heater coils are on the gas valve they are two round silinoids one with two pins to it and one wwith three. Follow the gas line to the gas valve on the gas valve you will see two quick connects that run to it. There is one screw and the plate cover will come off to give you access to the heater coils.
If you have anymore question please comment me back
