I purchased a used kiln and attempted to run it though an initial bisque fire (cone 04). The kiln turned off before the drop switch dropped and I don’t have a timer on my sitter.
I’m still waiting for the kiln to cool down but just through looking through the peep hole, it doesn’t appear my witness cones have bent.
I know the power to the kiln is good because I had a plug installed brand new just for the purpose. I ran the kiln up 2 hours on low, 2 on medium and it was on high for about 2.5 hours before it turned off.
Is anyone familiar with a similar sitter or have suggestions on what might have caused the seemingly early switch off?
