Hi everyone, Thanks in advance for your help! I am having some issues with a cress kiln FX 27-P. I am new to operating a kiln and have only successfully fired 1x to cone 04. I had no issues with the timer, kiln sitter, thumbwheel (rotated to different numbers throughout firing), and maintained power to the kiln for entire firing. I read the entire manual and follow instructions on kiln when programming settings. In my second firing- set kiln to 12 hour timer, cone 6 bar in kiln sitter, set it on slowest firing setting. Walked away from the kiln for maybe 2 hours- when I walked away it was on. I came back and it was off, set it again, same settings, it turned itself off within 30 minutes. Set it again, this time for a normal firing speed, it turned off. The plunger will stay plunged for a time limited period on its own. The kiln will stay on if use my finger to keep the plunger, plunged. No obvious issues inside kiln- kiln sitter bar has not been moved out of position or bent. Please help! Cress is not open until next week, same thing with local ceramics stores. Thanks again, Chelsea
