Does the ignitor glow?

its sparks, does not glow
Expert:  HVAC Guru replied 1 year ago.

Ok if it sparks do you get a flame for even a second or anything?

Customer: replied 1 year ago.
no, have taken off the gas line and there is gas running.
Expert:  HVAC Guru replied 1 year ago.

OK then you could have a gas valve issue..not likely though or just a bad ignition module...Very likely on that unit. The ignition module sends power to the gas valve when sparking it may be defective they just go bad all the time.
