I think the wiring is correct, correct gauge, also conduit and 100 amp circuit, all of it has been checked by Skutt techs, and the wiring from the box is how it comes from Skutt. It has worked fine for a decade like this as well and there is another 1231 next to it with no problems. Also, no heat on the wire or circuit during firing.
The 3rd test is firing right now and is on target. The second test came out perfect like the first. It seems like it may be fixed, but still pretty mysterious as the thermocouples had already been changed and checked several times. But the goal is a functioning kiln, so I'll be happy with that. I'm bringing the replaced thermocouples and wires to Perry to have checked at Skutt. It will truly be baffling if they find nothing wrong with them. I'll just be happy to be able to fire work in the kiln rather than simulated loads and tests. It's been an expensive and time consuming 18 months for both me and Skutt. Thanks for thinking through this with me.
If the zones were not connected to the correct thermocouples it would error out right near the beginning of the firing.
I totally had that backwards in my head, thought the center was firing hot! My bad.
I'd still check the resistance, though and make sure you've got the correct elements. Also make sure a center element hasn't burned out.
