15.7 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:
15.7.1 Place the probe of a temperature reader (A)
onto a heat sink or a metal plate in the centre of the
oven cavity and close the oven door.
15.7.2 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.
15.7.3 Once the oven is up to maximum temperature
check for a stable temperature reading.
15.7.4 Select the red X to fi nish the test, if necessary.
15.7.5 If the temperature reading is diff erent to the
maximum set point, scroll up (C) to select TEMP.
COMP. (Temperature Compensation) (D) and enter the
password.
15.7.6 Enter the fi gure from the temperature reader
on the keypad (E) and select OK to calibrate the SRB to
the thermocouple.
15.7.7 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:
1 Disconnect and isolate the oven from the
electricity supply.
2 Allow the oven to cool down.
3 Remove the oven casing.
4 Check the cavity temperature sensor wire and
connections.
5 If the wire and connections are ok; replace
the cavity temperature sensor (see Spares &
Replacement section).
6 Replace oven casing, switch ON and retest.
7 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).
15.7.8 Repeat the Temperature Control Test
procedure.
