I have the GMT070-3b Goodman furnace. I can here the gas turn on and I can light it by hand but will not light. It makes since to me that it is probably the Igniter if not that then probably the circuit board. Does anyone have the part number for the Igniter? There are 2 things hanging down pne on the right side and one on the left. Which is the igniter?

First off it is the igniter,and it would be on the right in the burner compartment it is black. On the other side is the flame sensor it is a small rod which has an orange wire that hooks up to it caint tell you the part # its just an igniter and its off a goodman unit all you need is the model # you have that already any more questions just contact me back.
