Full power firing rate. At this setting the kiln will fire at
its fastest rate. There are two ways to select full power:
1) Select in Single Segment mode.
2) Select a rate of 1799°F/999°C at the prompt in
Ramp-Hold mode. A fast way to do this is to press the
key once from . will appear.

segment. Rate is figured in degrees of temperature change per
hour. Example:
A temperature rise of 100° in two hours = 50° rate.
A temperature drop of 200° in one hour = 200° rate.

Trouble Shooter
Problem: Controller display is
blank. No heat in kiln.
I
Is the kiln connected to the power?
I
Has the circuit breaker tripped or fuse blown?
I
Is power reaching the wall receptacle?
Test with a voltmeter or test light if you are not sure.
I
Has the kiln switch box ½ amp fuse blown?
The kiln’s ½ amp fuse is
located in the kiln switch
box. Remove by pressing the
fuse holder and turning
counter-clockwise half a
turn. Check the fuse by plac
-
ing the probes of an ohmme
-
ter on the ends of the fuse. If
the ohmmeter reads less
than an ohm (digital meter)
or reads 0 ohms (analog me
-
ter), the fuse is okay. If the
reading is OPEN (digital meter) or infinity/no needle
movement (analog meter), the fuse is bad. Replacement

-
move the 4 screws holding
the controller faceplate to
the switch box. Lift face
-
plate out of box and let the
board hang on the box
with the back of the board
facing you. Plug the kiln
back in. Touch voltmeter
probes (in AC mode) to
both INPUT connections (the white and orange wires).
CAUTION: Do not let the back of the board touch a
grounded object. Make sure the voltmeter is in the AC
modewhen placing theprobes on INPUT connections.
Controller Power Input Test Result: No voltage
UNPLUG kiln. Check the switch box for disconnected
wires between the cord, transformer, and controller. If wir
-
ing is okay, replace the transformer.
Controller Power Input Test Result: 20 - 24 volts AC
Correct current is reaching the board from the trans
-
former. But since the board is not lighting up, it is probably
defective.Returnthe controller for repair or replacement.
