I have an older Armstrong Air furnace I am not sure how old it is probably 20 years or so.
Went to turn it on for the first time this year and the pilot light comes on and you can here it click on but it never blows any air out. It just keeps on going to eventually we turn it off. Any suggestions as to what might be wrong would be helpful.

Start with the usual stuff. Make sure voltage is getting to the fan control and if it is there check it at the blower motor.
