Temperature Control Test 15.7
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:
Place the probe of a temperature reader (A) 15.7.1
onto a heat sink in the centre of the oven cavity and
close the oven door.
Select ‘Temperature Control Test’ (B) from the 15.7.2
service mode tests. The oven heats up and cycles
at the maximum set point temperature over 30
minutes.
Once the oven is up to maximum 15.7.3
temperature check for a stable temperature reading.
Select the red X to finish the test, if necessary. 15.7.4
If the temperature reading is different to the 15.7.5
maximum set point, scroll up (C) to select TEMP.
COMP. (Temperature Compensation) (D) and enter
the password.
Enter the figure from the temperature reader 15.7.6
on the keypad (E) and select OK to calibrate the SRB
to the thermocouple.
Retest to check that the oven cavity 15.7.7
temperature reading is the same as the oven
maximum set point temperature.
If the temperature reading is unstable:
Disconnect and isolate the oven from the 1
electricity supply.
Allow the oven to cool down.
2
Remove the oven casing. 3
Check the cavity temperature sensor wire and 4
connections.
If the wire and connections are ok; replace
5
the cavity temperature sensor (see Spares &
Replacement section).
Replace oven casing, switch ON and retest.
6
If the temperature is still unstable repeat steps 1 7
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).
Repeat the Temperature Control Test 15.7.8
procedure.
