I've been a lurker for a while on this forum. Lots of great folks, and lots of great info!
My reason for posting is this: I've acquired a used Paragon kiln, a TNF 243, from a school district. It's seen a fair amount of use, but is not on it's last leg. Best I can gather is it's about 7 years old. Bricks are all still good, elements are testing out just fine as far as we can tell. None of them were bulging, or were broken.
It has a digital controller, the Sentry 2.0 12-key, which sort of worked at first, but then went south. The last time I fired it, the controller board had a bit of smoke coming from it.
The transformer has been replaced, as have the 3 relays. The wiring has been gone through thoroughly, connections were checked, and it all seems to be in order. The wiring coming in for the power has been done correctly, and is run according to code, so I have the correct 50 amp breaker and plug receptacle for the kiln.
So, since I've sunk a considerable amount of money into this kiln on top of what I paid for it, I'm considering replacing the controller box with one of the PID controller kits that I've seen on the internet, and actually first heard of on this forum in another post.
Does anyone have any experience with this sort of set-up, and how well does it work? I'm going to have to choose between spending a couple hundred dollars for the PID set up, or buying a new controller board for about $350.00.
I really like the idea of a digital controller, and was disappointed when this one failed so spectacularly.
Any input/suggestions/help/tips/pros/cons would be greatly appreciated. Hubby thinks the PID controller will work, but is just a bit unsure about wiring in the 3 relays, as the wiring diagram that the seller sent is only showing one relay.
Thanks in advance! â€‹Rebecca
