I have a Goodman GMS9 furnace. When the furnace starts the induction fan runs for about 15 seconds, the ignitor turns on but thats as far as it goes. The burners do not light and I don't think the gas valve turned on. I did find a loose condensate line (no clamp) on the heat exchanger. Also the induced draft blower is noisy and I suspect the bearings are starting to go. This is an intermittent problem and I would like to get it solved before colder temps set in
