Temperature Control Test
Measuring the oven cavity temperature
(Note; re-calibrating the Thermocouple with the
SRB is normally only required when the
Thermocouple has been replaced or the oven is
under or over cooking.)
Procedure:
1 Place the probe of a temperature reader (A)
onto a heat sink in the centre of the oven
cavity and close the oven door.
2 Select ‘Temperature Control Test’ (B) from
the service mode tests. The oven heats up
and cycles at the maximum set point
temperature over 30 minutes.
3 Once the oven is up to maximum
temperature check for a stable temperature
reading.
4 Select the red X to finish the test, if
necessary.
5 If the temperature reading is different to the
maximum set point, scroll up (C) to select
TEMP. COMP. (Temperature
Compensation) (D) and enter the password:
‘tcomp’.
6 Enter the number from the temperature
reader on the keypad (E) and select OK to
calibrate the SRB to the thermocouple.
7 Retest to check that the oven cavity
temperature reading is the same as the
oven maximum set point temperature.
If the temperature reading is unstable:
a) Disconnect and isolate the oven from
the electricity supply.
b) Allow the oven to cool down.
c) Remove the oven casing.
d) Check the cavity temperature sensor
wire and connections.
e) If the wire and connections are ok;
replace the cavity temperature sensor
(see Spares & Replacement section).
f) Replace oven casing, switch ON and
retest.
g) If the temperature is still unstable repeat
steps 1 to 3, replace the SRB (see
Spares & Replacement section), repeat
step 6. NOTE: reuse the existing PM
(Personality Module) on the new SRB
(enter Serial No. on reboot).
8 Repeat the Temperature Control Test
procedure.
