Set the oven at 260 °C (500 °F)
and measure the
temperature with an
external certified probe placed
next to the ceiling
chamber probe
Test 1
Setting 1
Setting 2
AF39 chamber probe number 2
over temperature alarm
(temperature over 300
°C
– 572
°F
)
End
Did the alarm
triggered?
Do you have
about 110 Ω at
25 °C (77 °F)
YES
YES
Check the oven parameter:
CHAMBER PROBE POSITIONING
has to be set as:
a. Front/back in the oven without
Smoker system
b. Ceil/floor in the oven with
Smoker system
End
Replace the
temperature probe
NO
NO
Do you
have a value
of the real cooking
chamber temperature
of about
260 °C (500°F)?
YES
NO
Do you
have about
110 Ω at 25 °C
(77 °F)?
YES
YES
NO
Replace the power
board
Te st again the
oven at maximum
temperature.
Do you measure a value of the
real cooking chamber
temperature of about
260°C (500 °F)?
NO
Load again the model
ID parameter using
the PARAM_S6 file in
the USB stick, test the
oven at maximum
temperature and
measure the cooking
chamber temperature
with an external
probe placed close to
the back/bottom
temperature probe
Te st the impedance
of CMB2 chamber
probe with the
multimeter set to
ohm. You should
find about 110 ohm
at 25 °C (77 °F)
Replace the power
board
Replace the
temperature probe
Te st the impedance
of the CMB1
chamber probe
with the multimeter
set to ohm. You
should find about
110 ohm to 25 °C
(77 °F)
