Are you sure it clicked to let gas on, or did it click to shut the igniter back off? Did you actually hear gas flow? Does your unit have a condensate trap on the outside with two black tubes going into it from inside the furnace? If so, is there water in the trap? If not, full it with water and see if the furnace starts up. Im assuming your furnace is a 90+. Do you have a plastic or metal vent? Actually, if you could give the model number of the unit it would help.

Ok, this establishes an 90,000 BTU 80% efficient furnace. Do you have and can you use a multi-meter?

Set the meter to continuity and unplug the harness (or remove both wires) from board. Check to see if you have continuity and if you don't replace the ignitor. If you do then set the meter to voltage and check the board while stat is calling for heat... let it cycle as you will only get 120v when it calls for ignition.

Sorry, I forgot to put in there you are removing wires / harness for the ignitor... getting late here, lol.

Sorry I was confused. In your original post, you said "the glo igniter lit up". Or did I mis-interpret the sentence? Either way, glad your up and running.
