    I am glad to have found this site!

    I have a Kenmore condensing upflow gas furnace high Eff and I can not get the gas to stay on (flame). The pilot light works. The only way I get flame is by jumping the gas vale wire with the piolt wire. This seems to only work for a little while as I imagine the pilot 25v power goes out with gas ignition on. the intermittent pilot control is a honeywell s-86 model.

    I am wondering if this is my problem or am I looking at the wrong thing. Ignition sensor was replaced last year along with blower motor and pressure switch. I figure that I am running out of parts to replace here so any help in saving me the trouble of throwing more at it would be appreciated.

    Welcome Tito:
    I would look at cleaning the vent and heat exchanger tubes. Quite often the problem is a blockage in the secondary heat exchanger where the tubes are very small.
