17.7 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:
17.7.1 Place the probe of a temperature reader (A)
onto a heat sink in the centre of the oven cavity and
close the oven door.
17.7.2 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.
17.7.3 Once the oven is up to maximum
temperature check for a stable temperature reading.
17.7.4 Select the red X to nish the test, if necessary.
17.7.5 If the temperature reading is dierent to the
maximum set point, scroll up (C) to select TEMP.
COMP. (Temperature Compensation) (D) and enter
the password.
17.7.6 Enter the gure from the temperature reader
on the keypad (E) and select OK to calibrate the SRB
to the thermocouple.
17.7.7 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.
17.7.8 Repeat the Temperature Control Test
procedure.
17.8 Soak Test
Checking the oven cavity integrity.
Procedure:
17.8.1 Place an oven/microwave safe container with
approx. 2 litres of water into the oven.
17.8.2 Close the oven door and select ‘Soak Test’ (A)
from the Service mode oven tests (maximum oven
temperature, 50% microwave power, maximum fan
speed).
17.8.3 Run the test (30 minutes), carefully checking
the oven casing, joints and door seal for signs of
steam or water escaping from the oven cavity.
17.8.4 If necessary, rectify any leaks and repeat the
test.
17.8.5 Safely remove the container from the oven.
17.9 Recommission Test
The Recommission tests are performed following
the completion of a service or repair to ensure
the oven is operational before handing back to
the customer.
Some of the tests have a countdown timer where
failing to carry out a test within the time limit will
cause a test failure and the Recommission test will
have to be restarted.
Procedure:
17.9.1 Select ‘Recommission Test’ (A) from the
service mode oven tests and follow the on screen
instructions to perform the tests. Do not select the
red ‘X’unless you want to stop the test.
17.9.2 After a test has successfully passed, select OK
to continue.
17.9.3 When all the tests have been successfully
performed the display shows the Recommission test
has passed, select OK to conrm.
17.9.4 In the event of a Recommission test failure,
the detail will be recorded in the Error log. Any error
should be rectied and the Recommission test run
again.
