My old Cress kiln has six dials in the front, each with a light. The kiln is plugged into a wall-mount Skutt kiln controller.
I'm attempting a Cone 6 firing, manually programmed. Somewhere around 2000F, the kiln stopped turning on. The controller tries to send power to the kiln, and you can see the all lights flick on for a split second. But they don't stay on. The kiln is just rapidly cooling now. (It's the kiln that's failed, not the controller.)
I have, in the past, had an issue with not enough power going to this breaker - but that was resolved by turning off various appliances in the house. And it was a completely different symptom. This is a new one for me!
