Thank you Neil and Bill for all of your advice. I was able to purchase the Solid State Timers from Artisan Controls - as you noted, they were a little expensive ($78.00 each) but I was not confident in my ability to install another infinite switch and eliminated the relays. The new Timers eliminated the clicking/chattering noise and now I can hear the timers cycling on and off properly. I really appreciate all of your help!

Attached are a photo of the serial plate and the element connection area. Thanks for your help.

I have a constant chattering noise when I start up my 40 yr old Duncan EA 820-2. I have just replaced all the elements, the relay, the switch and someone else replaced the Kiln Sitter for me. I fired the kiln empty with 04 cone in the Kiln Sitter on the Hi Fire setting. All the elements glowed red and the Kiln Sitter turned off the Kiln after only 1 hour 15 min. The cone slumped as it should. I have 2 questions - 1. Is the chattering sound normal? if not - any idea as to what makes the chattering sound/how to fix it? 2. is my kiln firing too hot to quickly? I will attach photos of the new parts added to the kiln. Thank you for your help.

thank you so much Neil and Bill!

I need to replace 40 yr old elements in my Duncan EA 820 Kiln. The element connectors are pretty corroded -so are the connectors on the Bars that connect the elements in each set of 4. Can this corrosion affect the performance of the kiln? Should I replace these connectors? If so, do you have a recommendation as to the type of connectors I should use ? thank you for your advice!

Thank you so much! I will give this a try!

I used a Cone 06 Bar in my kiln sitter and after 12 hours the bar did not slump and the kiln sitter did not turn off. Suspecting something was wrong, I fired the kiln again the next day empty and took a peek at the elements after about 20 minutes - the kiln was heating up but none of the elements were glowing. There is a clicking sound when I turn on the kiln - almost like something is turning off and on. After 1.5 hours the clicking sound stopped and when I peeked inside the top 4 elements were glowing red and there was no color in the bottom 4 elements. After 2.5 hours the top 4 are glowing and the bottom elements are dark. Do I need to replace the bottom 4 elements? Is the clicking sound an indication that something else is wrong? Any advice would be appreciated!

What do the settings mean on the knob? What do you use the Hi-Fire setting for? What do you use the Ceramic setting for? and what do you use the Over Glaze setting for?
