UNPLUG the kiln/disconnect the power. Remove
the 4 screws holding the controller faceplate to the
switch box. Lift faceplate out of box and let the con-
troller hang on the outside of the box with the back
of the board facing you. Then plug the kiln back in.
Program the controller to fire to 1000°F at FULL
rate in Ramp-Hold mode. Press
.
Put the voltmeter in DC mode. (It must be in DC
mode when testing OUTPUT voltage.) Touch
probes to the red wire and black wire connections.
Measure voltage when the relay clicks on.
Output Test Result: No voltage at red and black wires
The controller is not sending power to the relay. Return
the controller for repair or replacement.
Output Test Result: 10 - 14 v. at red and black wires
The controller is sending correct power to the relay. Un-
plug kiln/disconnect power. Remove the kiln switch box.
Look for disconnected wires between the controller, relay
and elements. Check the wiring diagram to be sure wires
are connected to the correct terminals. Be sure connections
are tight. If the wiring is okay, replace the relay.
Note:
To replace relay, see your kiln’s instruction and
service manual.
Problem: Kiln switch box ½
amp fuses keep blowing.
I
What size fuse are you using? Correct fuse:
AGC ½ A 250V AC
If the fuse is the correctsize, perform the following test:
Kiln Switch Box ½ Amp Fuse Power Test
UNPLUG the kiln/disconnect the power. Remove
the 4 screws holding the controller board faceplate
to the switch box. Lift
faceplate out of box
and let the board
hang on the outside
of the box with the
back of the board fac-
ing you. Disconnect
both wire plugs from
the back of the controller. Then plug the kiln back
in. Apply power to kiln. If fuse blows, replace the
transformer. (If the fuse does not blow, the problem
is a board or relay. Go to step 2.)
Connect the INPUT plug (orange, blue, and white
wires) to the board again. Leave off the OUTPUT
wire plug (the one with the red and black wires).
Program the controller to fire to 1000°F at FULL
rate in Ramp-Hold mode. Press
. If the fuse
blows, replace or service the board. (If the fuse does
not blow, the problem is caused by a short in the coil
of a relay. Go to step 3.)
UNPLUG kiln/disconnect power. Reconnect the
OUTPUT wire plug. Reinstall the board in the
switch box. Replace the relay.
