Probable Causes:
Defective Thermocouple
Disconnected Thermocouple Lead Wires
Defective Board
Electrical Noise
UNPLUG kiln. Remove the 4 screws holding the controller
board faceplate to the switch box. Lift faceplate out of box.
Look at the back of the board. You should see a yellow wire and
a red wire connected to connectors 10 and 11 (back of board).
(See diagram, page 22.) If one of these wires is disconnected or
loose, reconnect or tighten. (Grasp connector block to prevent
block from twisting.) The controller should work now. If the
wires were attached securely to their connectors, perform this
test:
1 Remove thermocouple
wires from connections
10 & 11.
2 Cut a paperclip in half. In-
sert a U-shaped paperclip
piece between connectors
10 & 11. Tighten screws.
3 Place the faceplate back
into the switchbox with a
couple of screws.
4 Plug in the kiln or turn on
the breaker. If the board
reads room temperature,
replace the thermocou-
ple. If it reads

couple and thermocouple lead wires are sold as a sin-
gle unit. Therefore, damaged thermocouple lead
wires call for replacement of the thermocouple itself.
If you still get a
message after replacing the thermo-
FaIL
couple, watch for an erratic temperature display. The problem
may be due to electrical noise. See "Erratic Temperature
Readings," page 20.

A kiln that fires this slowly may need new elements, voltage
may be low, or you may be trying to fire hotter than the kiln was
designed for. If it happens in the summer during hot weather,
it is likely due to low voltage during peak electrical demand.
