1. Empty the kiln.
2. Turn kiln on using a fast program such as FAST GLAZE (USr3) until elements are red.
3. Open the door carefully and check if each of the elements are glowing with approximately the same brightness.
4. This is an approximate method. The best thing to do is check the ohms on each element or circuit.

CAUTION: The power does not turn off when the lid is opened. Do NOT put your hand inside the kiln while it is on.
