or before reaching
the end
temperature.
Possible cause
The kiln is not supplied
with electricity.
The electrical wiring is
faulty.
Defective heating element
(breakage or no longer
efficient due to age).

working.
The controller cable is not
connected to the kiln, or
the connection is
incomplete.
The kiln was loaded with
too much ware.
Defective heating element
(breakage or no longer
efficient due to age).

working.
In the case of a multi-
phase power connection,
one or more phases are
not working.
Power failure
The fuse at the building's
mains connection has
