Once again,
My heater will come on, the jets ignite, it stays on for a while then a click noise and it shuts off. Then I see the self ignitor glow, the jets are relit, and then they blow out. I read about cleaning the sensor. Where is this located and how do i clean

THANKS

sounds like a dirty flame sensor frist look on the left side of the burner cabent look for metal flame rod take a 1/4 nut driver unscrew the screw and pull it out clean with a piece of sand paper and then reinstall it and turn the power back on your heat sould work but if you continue to have this problem you might need a circuit board and a new sensor for the unit cause the board might not be reconizing the flame i would have a heating and cooling company run a serve call for you so that every thing is done properly better safe than sorry
