PROBLEM PROBABLE CAUSE SOLUTION
Circuit breaker or fuse blows
instantly after kiln is turned on.
Circuit breaker or fuse blows after
a while.
Kiln warms but does not reach red
heat.
Excessive time is required to reach
maximum kiln temperature.
One pilot light does not light.
Short circuit.
Defective house circuit breaker.
Incorrectly wired wall receptacle.
Burned out element or worn out
element.
Incorrect supply voltage.
Loose connection.
Check with volt-ohm meter to see
that you have at least 5 ohms
between all prongs on kiln plug
with thumbwheel set to 9. If
reading is less than 5 ohms, check
kiln wiring for short.
Check electrical specifications to
see id your fuse or breaker is large
enough. If not, call a qualified
electrician. Do not merely install a
large fuse or breaker. Replace
circuit breaker or fuse(s). Clean
wire and tighten connections to
circuit breaker or fuses. Do not use
aluminum wiring. Use only copper
wiring. Ventilate kiln room to
prevent excessive heat in area with
fuse box. Remove other appliances,
lights, etc. from the kiln circuit.
Have electrician check wall
receptacle.
Green wire in kiln cord is
connected to case ground. Black
and white wires in kiln cord are
“hot” and connected to controls.
White in house wiring is the neutral
and is eventually grounded in the
main house electrical panel. A
qualified electrician is required for
this work. Do not attempt this work
yourself.
Check by closing lid and turning all
switched to high. In three minutes,
turn switch off and pull plug from
electrical wall receptacle.
Cautiously feel brick by each
element. If one element is relatively
cool, either the element is burned
out or there is no power to the
element. Check with ohm meter.
Replace element if necessary.
Operating a 240 volt kiln on 208
voltage. Call your electric company
and check your voltage.
Replace pilot light and retighten
connection.
