The connection wires of the core probe
are disconnected from the power card
Check the electrical circuit connection
Damaged core probe Check and eventually replace the probe
Damaged power card Replace power card
The minimum distance between free
room and the appliance is not respected
Keep the minimum distance between
ovens and walls as suggested in the
Unox instruction guide (5 cm to 10 cm)
Defective capacitor - the motor takes
longer to reach the normal speed,
Check and eventually replace the
capacitor
Damaged motor bearing Replace the motor
Damaged power card Replace power card
The sensor has detected a temperature
over 318°C in the external part of the
chamber - even if the probe was setted
to lower temperatures
Check the effective chamber
temperature:
- if the oven probe is right the Safety
Termostat is defective and it should be
replaced
- if the temperature misured by the oven
is wrong a probelm occurred in the
chamer probes, refer to EF1 or EF2 for
the diagnosys and fixing.
The sensor has detected a temperature
over 318°C in the external part of the
chamber - when the chamber
temperature was setted to approx 300
°C
Control that the minimum distance
between ovens and walls as suggested
in the Unox instruction guide (5 cm to 10
cm) is respected
