Lennox G10 Blower Control

I have an older Lennox G10 furnace G10RC2-110-1 and the blower motor stays on for 20 mins after the flame cuts off. I pulled the blower control switch and that appears to be the issue. Its part F41T52 7T04 110C. Can anyone tell me where I can get this part or if there is a replacement?

Lennox G10 Blower Control

that might be a Klixon thermal disc that closes when it heats up controlling the fan/on to that.check the time the fans stays off when you call for heat right after the burner comes on...do it with a cooled down heatx,run the unit in fan/on for 5 minutes no heat call.the on and off cycle for a fan on a furnace should be somewhat close thru the fan limit disc.
