I have a Tempstar 5000 high efficiency furnace that is about 15 years old. Recently it started reigniting every 30-45 seconds. I have researched it down to possibly the flame sensor but I dont know where it is located (no owners manual). Can you direct me to where it is located so I can clean it?
I wanted to sqeeze one more winter out of the unit since our money is tight right now. Can anyone point me in the right direction or possibly offer more suggestions?

Thanks in advance

flame sensor senses flame.look where the flame is for a steelrod usually with a ceramic base and a single wire plugged into the end of it.

I am having an identical problem. I am glad that I did not run off and start cleaning the flame sensor if that did not help you.

more bad news...
I replaced my ignition module and my fan limiter and am still having the same problem.
any help guys/gals?
