A temperature rise of 100° in two hours = 50° rate.
A temperature drop of 200° in one hour = 200° rate.

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 lo-
cated in the kiln switch box. Re-
move by pressing the fuse holder
and turning counter-clockwise
half a turn. Check the fuse by
placing 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 meter), the fuse is
okay. If the reading is OPEN (digital meter) or infinity/no
needle movement (analog meter), the fuse is bad. Replace-
ment fuse:

Is the controller receiving power? Test the power IN-
PUT connections on the back of the controller with a
voltmeter.
Controller Power Input Test
Unplug the kiln. Remove the 4
screws holding the controller
faceplate to the switch box. Lift
faceplate 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 volt-
meter 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 mode when placing the probes on INPUT con-
nections.
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. Return the controller for repair or replacement.
Controller Power Input Test Result: less than 20 volts
Did you recently replace the transformer? It may be the
wrong voltage. The voltage is below 20, which is not enough
