Thanks for your input. I'll check the element resistance and the thermocouple.

I continued to fire. Again, the firing didn't seem to take longer than it normally does. The elements both glow brightly when test fired. I really need to solve this problem since I want to sell this kiln and buy a different model. I suppose I could replace the relay and see if the error goes away. Any advice?

I have a Fusion 14, 120V, s/n UNK447230, p/n 4A21141BEM. The last 2 times I did a full fire I noticed the Sentry 2.0 controller gave an error message of FTH at about 1400. But the fire cycle completed normally, reaching 1480 degrees in about the same time as usual. What might cause this? Don
