Trying it for the first time this year, unit is 9 years old. The furnace blower keeps running but there's no fire and after a few minutes it cuts off. LED is solid. Could the ignition switch be shot?

Thanks.

No one here has any thoughts on this??

Do you mean the main blower or the little inducer blower? If it is the main blower, you may have a bad temperature sensor. I am surprised you aren't getting a trouble code. By solid, you mean staying on?

Thanks for the reply. I believe the main blower is working because air is coming out the registers, it kicks in for a few minutes then cuts off. And yes, the LED stays on and does not flash.
