TROUBLESHOOTING

TEMPERATURE

Temperature too high

1/ controller set too high-see section 6.4
2/ controller failed on

call Customer Service

3/ wiring error

call Customer Service

Chamber temp spikes over set point and
then settles to set point

Recalibrate

see section 6.3 and 6.4

Temperature too low

1/ Thermostat set too low

see section 6.5

2/ controller set too low

see section 6.4

3/ unit not recovered from door opening

wait for heating indicator to turn

off
4/ unit not recovered from power failure or being turned off

oven will

need 1 hour to warm up and stabilize
5/ element failure

see if heating indicator is on; compare current draw to

data plate
6/ controller failure

confirm with front panel light that controller is calling

for heat
7/ Thermostat failure

confirm with front panel light that it is operating

correctly
8/ wiring problem

check all functions and compare wiring to schematic

in section 9.0 - especially around any areas recently worked on
9/ loose connection

call customer service

Unit will not heat over a temperature that
is below set point

1/ confirm amperage and voltage match data plate
2/ confirm that set point is set high enough

turn Thermostat all the way

clockwise and see if heating light or safety light comes on
3/ check connections to sensor
4/ check calibration

using independent thermometer, follow instructions

in section 6.4

Unit will not heat up at all

1/ verify that controller is asking for heat by looking for heating indicator
light

if pilot light is not on continuously at initial start up, there is a

problem with the controller
2/check amperage

amperage should be virtually at maximum rated

(data plate) amperage
3/ is the Thermostat set high enough?

for diagnostics, should be fully

clockwise with the pilot light never on
4/ has the fuse/circuit breaker blown?

Indicated chamber temperature unstable
