Ive found out thru experience thats its not the glaze fit but rather the clay body that cant handle the sudden temp shock. Thru research and long conversation with Tony at digitalfire we came to the conclusion thatthe clay body I was using had an unusualy high amount of silica.... micro crystalline silica.  A change in the Hawthorn clay ore body prooved to be the culprit.   This led me to completely change the clay body Im currently making and using now.  With the clay body I have now I can take a mug straight from the freezer and pour in boiling water with no detrimental effects...

Hi @grumpykidstudio , I swapped it out for a Bartlett V6 controller from Pottery Supply House / Euclids. They had a used one that I got a bit of a discount on. I use it as a bisque only kiln since the elements are such a pain to replace in this kiln (non segmented) and use 2 thermocouples. The board fit without having to alter the box. The original controller had very limited options and I was using it for glaze firing originally but after a little while a lot of the readout was illegible as parts of the numbers and letters blanked out and it had some stuck pads. I'ld contact Tuckers, send them some pictures of what you have and ask if they have a used board you can swap over. (or other vendors who might have a used board if you want to save a few bucks) Have to say I love the Genesis Controller on my ConeArt kiln.

grumpy, if the kiln has been stored where flying insects can get to it, check for tubes of clay in the tiny spaces you might find. check the slits in the metal box. 

It came with just the one thermocouple but when I replaced the controller I decided on using 2. The boards now  have the option of 1,2 or 3 thermocouples being wired up.
