Oh, THANK you for responding. I love that little kiln.
The cirquit breaker trips each time I set the kiln to
High Fire, not with any of the other settings. But I
was told by my instructor/friend that High won't do it
for bisque.
It is a Duncan K-10..can't find other numbers/codes on
the kiln itself. This is on the kilnsitter, which is
also Duncan.
I've tried to prop up the metal lever that falls down,
but it still trips at High-Fire. Not always
immediately - maybe a few minutes?? No burning odor,
now fireworks.
If there is something I can do, I'd be a happy camper
indeed, since there's no way I can afford a new
smallish kiln right now.
Thank you again, Arnold. Marianne

Marianne, I'm not sure what you mean by "circuit breaker."
If you mean the circuit breaker in the electric panel of your building, then
you may have a weak breaker that needs to be replaced, or a short circuit in
the kiln.
If you mean the Kiln Sitter circuit breaker, you could try this:
When the Kiln Sitter trips, raise the weight and press in the plunger.
Gently lower the weight. The Kiln Sitter is now firing on manual and will no
longer shut off the kiln.
Maybe the Kiln Sitter needs to be adjusted with the firing gauge.

When you said trip the fuse I presumed you meant a circuit breaker of
some kind. Which I suppose a kiln sitter is, but it breaks the
circuit for a different reason.
I don't use my kiln sitter for glaze firings. I short circuit it's
mechanism by using electricians tape to hold the lever onto the wiring
box of the kiln. Of course there is no cone in the sitter. The
answer is to just not use the sitter. It has been advised to put a
cone in the sitter that is two or three cones higher. I think it's a
silly idea. If you have an automated computer then it makes sense,
but it doesn't sound like you do. Just tape the lever up and use
witness cones (and a pyrometer if you can).
Mark.

Hi Marianne,
You're dealing with the right guy on this subject since Arnold works at
Paragon and they bought Duncan Kilns.
First you should remember that a picture speaks a thousand words. Get your
hands on a digital camera and take pictures of the control panel. Send them
to Arnold.
From there he can isolate the model number and from there identify parts.
Diagnosing this electrical problem is fairly easy. There are a couple of
reasons why the breaker may be doing this. Most commonly you may have a
similar or slightly different amperage rating on the kiln and also on the
breaker. For example if your kiln is rated at 20 amps and you have a 20 amp.
breaker on the circuit, you might think that they are compatible when they
are not. A 20 amp kiln requires a 25 amp. (or 30 amp.) breaker. Since kilns
are Resistive circuits you need to multiply the rated amperage by a factor
of 125%. You may want to try an old trick of mine to see if this may solve
the problem. Go to Lowes or Home Depot or your fav. hardware store and
pick-up a new breaker. Replace the old breaker with the new one. Sometimes
the old breaker will still work but if it has been tripped too many times it
is basically no good. This is also one of the simplest (and cheapest) things
to do when your breaker keeps flying open. Have someone check the wires that
go to the kiln to make sure they are the correct gauge. After that suspect
the kiln.
May you easily find your problem.
Les H.
