@Steve1 – I want to run this by you. The temp on the big glass kiln is “stuck”. We went back to run it, and it was sitting at 82 degrees. A bit warm for the warehouse. As we loaded it, it never changed. Then, when I fired it (because the oddity hadn’t struck me yet), it pretty quickly went to a “failure to heat” error. I fired it up one more time, and it went to an error again.
In your opinion, is it likely that this would be fixed by replacing the thermocouple? Or might it be an issue with the controller? The kiln is actually heating. I just went to move the glass to a different kiln, and it was probably over 100 degrees still. But the box still says 82.
