Problem: Controller display is
blank. No heat in kiln.
■
Is the kiln connected to the power?
■
Has the circuit breaker tripped or fuse blown?
■
Is power reaching the wall receptacle?
Test with a voltmeter or a test light if you are not sure.
■
Has the kiln switch box
½ amp fuse blown?
The kiln’s ½ amp fuse is
located in the kiln switch
box. Remove by pressing
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 ohm
-
meter reads less than
an ohm (digital meter)
or reads 0 ohms (ana-
log meter), the fuse is
okay. If the reading is
OPEN (digital meter)
or infinity/no needle
movement (analogme-
ter), the fuse is bad.
Replacement fuse:
AGC 1/2 A 250V AC
