The kiln is plugged in, but there is nothing on the display.
First check your circuit breaker to ensure it has not tripped. If the circuit
breaker is okay, check the fuse. The fuse is located on the bottom of
the KM 1 Controller and on the lower left side of the kiln mounted
controller. Turn the knob a quarter turn counter-clockwise to remove the
fuse. Check the fuse wire, and if broken, replace the fuse. If the fuse
is smoky, replace it. After the fuse is replaced, if the new fuse blows,
check for other possible causes. A blown fuse may be caused by a
short in the circuit or a power surge.
Some segments of the display are dimmer than others.
When a few segments of the LED-display become dimmer than the
others, the problem may be the result of age, indicating the circuit
board may soon fail. Another possible cause is exposure of the
controller to high heat. This situation needs attention. Do not use the
kiln when this problem is present. Contact your distributor.
The thermocouple is flaking.
Flaking is normal with Type K thermocouples, especially when high
fired. Use a soft bristle toothbrush to remove the flakes and vacuum them from the kiln so they do not attach to
your ware. Remove the thermocouple element periodically and check it for thinning.
The end firing temperature is different now than when I first got my kiln and the results do not
seem quite right. What should I do?
After about 50 Cone 6 firings, or 150 Cone 04 firings, it is necessary to replace the thermocouple element. When
the temperature seems to drift, it is an indication that the thermocouple is becoming thinner and wearing out.
Another possibility is a cone correlation difference. As elements age it takes longer and longer for the kiln to reach
temperature. ConeFire Mode programs will automatically lower the ending temperature to compensate for the
added heat work induced by the increased time.
