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
Test 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
Test 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
Test the impedance
of the CMB1
chamber probe
with the multimeter
set to ohm. You
should find about
110 ohm to 25 °C
(77 °F)
