I have a bryant furnace about 9 years old. I went to fire it up for the first time this year and it wouldn't light. The evacuation fan comes on and just stays on. I don't hear the gas relay click and the glow plug doesn't go on either. I cleaned and tested the flame sensor and still nothing happens. Yes... the gas is on. Does anyone have any ideas what my problem could be??

Check to make sure pressure switch or switches are being pulled closed by draft inducer(evac fan) Check to make sure exhaust and intake vents are not blocked. Check to make sure hose and ports between pressure switch and draft inducer are not plugged and have no water in them. Do these simple checks, and we will take the next step.

I'll check everything you listed... Thanks.
