move by pressing on the
fuse holder and turning
counter-clockwise half a
turn. Check the fuse by
placing the probes of an
ohmmeter on the ends of
the fuse. If the ohmeter
reads less than one ohm
(digital meter) or reads 0
ohms (analog meter), the
fuse is bad. Replacement
fuse:
AGC ½ A 250V AC
Note: If you do not have an ohmmeter, visually in-
spect the fuse. You will see a thin strand of unbro-
ken wire in a good fuse. The wire usually appears
broken in a burned fuse.

If the circuit breaker trips after the kiln has fired for
awhile, make sure no other appliances are operating on
the same circuit as the kiln.

breaker trips im

Ceramic Fiber Repair
If glass, ceramic glaze, or other materials drip onto the
firing chamber, repair before the next firing. Otherwise the
glaze will remelt and embed deeper into the fiber.
1 Unplug the kiln.
2 Cut or scrape the ceramic
fiber to remove the con

taminant. Remove aslittle
fiber aspossible. If a heat-
ing element is located
where you are scraping,
avoid touching the ele-
ment.
Cleaning or Replacing the
Glass Viewing Port
Never fire a kiln equipped with the glass view port hotter
than 1700°F/926°C. Firing hotter will damage the glass.

screws holding the
glass cover.
