I've got a 2nd handParagon DTC600C kiln with a broken on/off toggle switch and while the control board seems fine, the kiln won't heat up because of it. Paragon says I'd need to replace the whole control board, which is expensive, but my electrician thinks he can wire in a new switch if we can see how its connected. If anyone has the same kiln and can share a wiring diagram or photos of the back of the switch, I'd really appreciate it!
