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.
Circuit Breaker Trips
■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.
■If the circuit breaker trips im- mediately after the kiln is turned on, the kiln may have a short circuit. Un- plug the kiln. Re- move the bottom cover and look for a loose wire touching the case.

Kiln Repairs
Door Latch
Adjustment
Adjust the two screws on the door latch to change the spring ten- sion.
N o t e : Do not loosen the screws too far, or they could fall out.
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.
1Unplug the kiln.
2Cut or scrape the ceramic fiber to remove the con- taminant. Remove as little fiber as possible. 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.
To remove the window:
1Remove the four screws holding the glass cover.
2Remove the glass. Clean with glass cleaner. To remove scratches, take the glass to an eye glass polisher.
