    I have a secondhand Paragon Glass Series 7 kiln, with a Sentry Xpress 4.0 Controller.

    Today, when starting a full fused program, I got a message reading “tc” which means Thermocouple Failure. I got the message in twice in the past but then it went away and i was able to fully finish the program.

    Now, it is on all the time along with “FAIL” So, I am assuming that I will need to change the termocouple.

    Is this something that I could do myself or should I call in a local kiln replace shop that is authorized to work on Paragon kilns. I am not unhandy with a screwdriver, but not overly handy either.

    I am first going to check to see if it a loose wire as well.

    Ideas, thoughts, comments?








    I’ve never had to do it, but you should be able to do this yourself.

    I called Paragon. They directed me to do the paper clip test. I followed the directions and determined it was the thermocouple and not the controller board. Ordered a new one, got it yesterday, followed the directions and I am back in the fusing mode today.


    Wasn’t too hard. Needed a second pair of hands to help at times but that significant others are for, right?


    Happy Holidays Everyone!
