Howdy y'all! Last time I posted I had an old Paragon that was pretty rough; I never got it to work and recently bought a newer kiln from a family friend. I got an Evenheat kiln with a DTC 100C controller, bricks all in perfect shape and hardly ever fired. My first bisque fire went as well as anyone could hope for and when I attempted my first ^6 glaze fire, that's when stuff went tricky. I noticed toward the end of the firing that the controller was reporting the temperature erratically -- jumping hundreds of degrees each click, displaying a range from 1700F to 2000F. I turned the kiln off and it had wayyy overfired. The ^5, ^6, and ^7 cones I'd put in were a puddle on the kiln shelf and all my wares were bloated and ugly.
Today I opened up the controller, tested the resistance on all the elements (just in case), checked all the wiring, and did a "paperclip test" on the thermocouple terminals which reported back room temperature. A Paragon branded troubleshooting guide for this controller says this indicates I need a new thermocouple.
What brand thermocouple do I need? Since this kiln/controller is no longer made I'm not sure what replacement I need. Will any Evenheat Type K thermocouple work? Thanks!
