Hi everyone. I am having a problem with my furnace. The ignitor won't lite the gas. I can lite it with a long match and it works fine until the thermostat cuts it off. I changed the ignitor thinking that was the problem, but it still won't lite by its self. How do I check to see if I am getting voltage to the ignitor, and how much should it be? If I am not getting voltage then what else could be wrong?
