If the furnace has a pilot, then it would be situated in the pilot flame. If you have a hot surface igniter then it would be in the burner flame path that is furthest from the igniter.

age & model of the Ducane would help.

post some pics of it with the cover off. Ducanes can be a HUGE pain in the butt to get at the sensors. Some of them have Smartvalves too and you don't really ever want to try clean that sensor as it is built into the pilot burner which breaks the HSI easily. I have not had a lot of issues with the sensor getting dirty on smartvales, more the valve itself. If the gas valve has a number like SV9500xxx then it is a smartvalve.

You need replace the whole then. Its called sensor/ ignitor you are better off replace whole then. Must the time if you try to clean that small flame sensor you will end up breaking the rod. The cost can be under 140.00 online price. You have a smart valve gas valve that is a very important part need updated. P.s be really careful replacing it.
