  1. 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.
  2. Hi Team, I purchased an old Cress B-1411 with 2x Thrumwheels and a kiln sitter. I went to bisque fire to cone 04 and after 14 hours and fully cranked it did not hit temp. I cranked the bottom thumb wheel, and see the indicator light on, and see the bottom coil become red hot. I also here the relay pulsing. When I crank the top thumb wheel the indicator light comes on but none of the coils become hot. I had an electrician friend come by and check the pulses. The top relay does not produce much of any output. I do not see any visual breaks in the coils. My first question is, based on these observations, can I accept that the top relay needs to be replaced? Why is only the bottom most coil getting hot vs. the bottom 2 or 3 (6 rows total)? Ideally this kiln automatically increases its temperature vs. a thumb wheel. If I am going to have to replace one of these relays I would rather replace it with an automatic firing relay that has firing speeds. Is this an easy change or is adding a dial that has a firing speed complex and pricey? Any information / help would he great. Also, if you could let me know the best product to replace the broken pieces that would be amazing. Thanks, Jesse
  3. For some back story, I acquired an AIM kiln model #2327hc (never heard of them until I got this one) about 5 years ago from someone who had it in their basement. It's been in my basement since then until I just made space to hook it up. It hasn't been fired in at least 7 years so I had no idea if it would work. And it doesn't. I switch the kiln on and a red light comes on indicating power. I flip the other switch to "Run" and nothing happens. The kiln doesn't heat up, click, or the percentage lights and "HEAT" light doesn't come on. I have a Skutt kiln at my work that I've done work on, so I'm familiar with how the kiln should be sounding and responding. The interesting thing about this aim kiln is when I go to switch it off, for a spirit second inbetween moving the switch from on to off I hear the clicking sound that the relays make when pumping electricity into the elements. I'm pretty sure the wiring is fine, the kiln sitter is fine, I'm just not sure if the relay is the issue or if the circuit board in the Fireright is broken. It's an old kiln and things are dusty, but visually nothing looks broken. Based on some mis-matching screws I can tell someone did repairs on this before, but I honestly have no idea when the last time this was used. Does anybody else have an oldish aim kiln or a fireright jr controll box? Let me know if you've run into problems like this on other kilns even. Thanks! Pardon any misspellings, this is on my iPhone. -Ben
