If you find yourself in this section of the manual please remember that Skutt and your Skutt Kiln distributor are
here to help you as long as you own your kiln. If you are unable to determine the problem, or just need to order
parts, please let us know.

If there is no display, check to see if the kiln is plugged in and the breaker has not tripped. If there is a
display, double check your programming instructions. The kiln must be in Idle Mode to start.

Make sure the kiln is connected to the proper voltage. After extended use the elements in the kiln wear
out and eventually need to be replaced. Look for possible breaks in an element. Elements can break if they are
contaminated by bits of glass. If an element is out, it will not glow. Program the kiln to at least 500 °F and look in
the kiln to see if any individual elements are out.
Kilns cycle power on and off through relays. If a relay goes out, 1 or more elements in the kiln will not
function. Look at the wiring diagram to determine if elements not glowing are connected to the same relay. If they
are, chances are that relay needs to be replaced. Skutt recommends to replace all relays at the same time.

The thermocouple, which looks like a metal tube protruding into the kiln chamber, measures the temperature in
the kiln chamber. As thermocouples begin to wear out, they slowly drift in the direction of an overfire. If you have
noticed that your projects have become increasingly overfired, it may be time to change your thermocouple. If you
are comparing your results to how they fire in other kilns, it is important to remember that every kiln fires slightly
different and it may be necessary to adjust your firing programs.

Kilns cycle power on and off through relays. If a relay sticks on, 1 or more elements in the kiln will stay
on. Skutt kilns are specifically designed to split the power between 2 or more relays, therefore, the likelihood of a
severe over fire is extremely unlikely. Look at the wiring diagram to determine if elements glowing are connected to
the same relay. If they are, chances are that relay needs to be replaced. Skutt recommends to replace all relays at
the same time.
