Help? I have replace the elements in my lid and reconnected everything. When I turn it on it is throwing the GFI. Any ideas? Is it a relay switch. I have a new one, should I try this?

if you have a gfi on it that is tripping, then you've mis-wired it and there's a short to ground somewhere. look for an element wire that is touching the metal shell somewhere.

If you determine the kiln is wired properly, check your GFI and your breaker.

GFI breakers are not recommended for kilns.

Q: What is a GFCI or GFI Breaker or Outlet AND Why might it trip when used with an electric kiln?
A:
What Is A GFCI Or A GFI Breaker Or Outlet?
A 'GFCI' or Ground Fault Circuit Interrupter, sometimes called a 'GFI' or Ground Fault Interrupter is part of either an outlet or a circuit breaker.
It is typically required for added safety on any circuit that may come in contact with water, like outdoors, or kitchen, or bathroom.
A GFCI measures the amperage on both the hot and the neutral wires in a 120 volt circuit, or it measures amperage on both hot wires in a 240 volt circuit.
If there is more than about a 5 milliamp difference (5 thousandths of an amp difference) between the amperage readings of the wires the GFCI acts like a circuit breaker and shuts the power off.
Why Might It Trip When Used With An Electric Kiln?
In a kiln, the firebrick is not a perfect insulator, so a tiny bit of the current leaks from the elements to the safety ground and unbalances the current in the 2 hot wires.
The resistance of the brick goes down as the temperature goes up so the kiln may be able to start a firing and but the GFCI would probably trip as the temperature went up.
Above 1700 F is when the firebrick has a significant drop in resistance.
Due to the nature of the firebrick in a kiln, GFCI protected circuits are not recommended for use with the power circuits in electric kilns without special element insulators.

We have GFI breakers for most of our regular basement outlets. Everytime we ran the table saw, the breaker tripped. If we plugged it into a non-gfi outlet, we didn't have the problem. Learned from a construction friend that this is a problem they come across when working on someone's house and plugging high power tools into GFI's
