It'll be fine.

If the controller is saying the firing is complete, then you've got a stuck relay. Not at all unusual. You'll have to unplug the kiln to get it to cool down.

Definitely has the symptoms of a stuck relay and an E-2 error which most often means stuck relay so time to replace. With respect to tight connections, I have never seen a well made tight connection create an issue, more often a connection that has loosened causes heat, arcing, more heat and failure at the connection or the device such as a relay. If the connection is tightened so much the connector begins to strip, then obviously too tight and needs a new connector properly and securely tightened.

The program finished and I just unloaded the kiln this morning - everything looks good (hallelujah!). Hopefully I'll get the new thermos in early this week. Thank you again so so much for your help!

Let it run and see what happens.

Thanks, Roberta! I do luckily use a firing log. Mine has about 100 now since I've had it, with a couple firings by the previous owner. I will try out that paper trick. Thanks!

Yes, it sounds like they need replacing.

Great - did that and the measurements should be 9.7 for a e23T-240. My measurements were 11.3, 11.3, 10.85, and 10.85 (so I calculated a reduction of 11.6% and 11.2%. Assuming I should replace the elements?
I didn't see the max temp but I know that it got to at least 1600 before I went to bed. I have noticed my firings taking longer than usual so I'd guess that was the elements as well...

Just moving this to the equipment section so it gets better visibility.

any good ceramics outlet  that carries glaze materials will carry it. If you are kiln building and just need some sand the lumber store carries lesser quaility sand
