    Thermocouples are usually generic (unless the furnace has a Honeywell Smartvalve). You should be able to get one at most hardware or big box home centers.

    How old is this furnace? Are you sure it even has a thermocouple?

    Grady, have you really ever seen a smart valve that utilized a thermocouple?

    Mygirlsdad, having (thankfully) only worked on very few Smartvalves, I may be thinking of something other than a thermocouple. Do they not use a very small thermocouple to prove pilot?

    I honestly don't know. I just assumed anything new enough to be related to a smart valve would be more of a flame sensor vs a thermocouple. They serve the same purpose, but are actually quite different. I have to admit, when I see a smart valve, I shudder. There is a reason the smart valves have gotten the nickname "dumb valve". I honestly don't know much about trouble shooting the actuall smart valves, and Im not afraid to admit it. I am certainly not afraid to learn, so the more info I can get, the better tech I can become. Basically what I am getting at is that you may be completely correct. I honestly just don't know on this one.

    Seems you & I are in the same boat on this one. I do have to admit, after doing some research on Honeywell's new & "wonderful" website, the Smart(?) Valve does use a 2 rod flame sensing system as opposed to a thermocouple.
    Wonder what I was thinking about with a tiny thermocouple??
