Why Don't Elements Glow Outside The Kiln.

Recommended Posts

One more question, why does everybody attach all the electrics to the outside of the kiln where it gets hot and moist? Is there a reason not to run wires to the elements from a seperate box or is it easier to manufacture them that way + less wire.

 

It's easier and faster and therefore cheaper to attach it all to the side of the kiln. Easier to ship, too. There are some kilns, such as the L&L Davinci models, that have all the electronics housed in a free-standing box, however that's because there's just too many parts and big relays to fit into a kiln mounted box. That's a good question, though, because relays, and electronics in general, last longer if they are kept cool. I see more relay failure in certain brands of kilns due to their design.

Yea that is what I thought, easier and faster.

 

I might try moving my relays off the kiln as I think I have enough wire left over to do that. Now it is fixed I would like to keep improving on its life span and remove as much of the electronics away from the water vapour and heat generated in the kiln.

I don't think the water vapor is such an issue inside the control box. Heat is the big culprit. Humidity from environment will corrode the electrical way more than vapor from the kiln, as the vast majority of the kiln vapor goes out the lid, peeps or vent.

Twisting the ends of the element with an extra piece of wire reduces the electrical resistance at the pigtails. If an element connector is loose, however, the connector will glow pink. The connectors and terminals must be tight. A loose connector on a relay will produce enough heat to destroy the relay.
