A couple years ago, I got a Duncan EA-820 manual kiln off of Craigslist. Paid about $50 for it. My garage was already wired with a 240v outlet, so I was excited to start exploring pottery. However, when I turned the kiln on, I heard a clicking so rapid, it would more aptly be described as a chattering. After some basic troubleshooting and Googling, I found it was the relay which was clicking. Thinking, perhaps the relay was bad, I replaced it. The new one not only clicked repetitively, but promptly began to melt. Frustrated, I moved on to another project and then life got in the way. My kids have recently developed a huge interest in pottery, so I'm giving the kiln another go. I've been able to find wiring diagrams online and everything internal to the kiln appears to be wired correctly. I've got a 240v outlet on a 40amp breaker with 8 guage wire, so that seems to be in line as well. Any idea what could be causing the relay to act this way? I'm stumped and before I go down a rabbit hole, I thought I would check to see if maybe I was missing something obvious or if anyone in the forum had gone through a similar experience.
So a few weeks back, I bought a used Brent wheel and an old Duncan 1029 kiln for $200 at a yard sale. A while later, I noticed the manufacturer's plate on the side of the kiln's control box says max cone 8, but max temp 2345F. So which one do I pay attention to? I've never fired to cone 10, but it'd be nice to be able to give it a shot if it wouldn't destroy the kiln. TIA! Sloan
