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
