5.20 Tracing oven cavity fan faults

(Refer to Technical Overview Section 2.7)
PROCEDURE:
If oven cavity fan will not operate
1. Enter Technician Mode diagnostics to test the oven cavity fan operation. (refer to
Diagnostics Section 4.3)
2. If the oven cavity fan operates in diagnostics but not in normal operation. Check for
door switch faults. (refer to Section 5.25)
3. Test for 220/240volts across contacts or substitute the fan with a dummy load.
Replace the fan if tests are good. (refer to Servicing Instructions Section 7.18)
4. Check the continuity of the fan wiring circuit back to power module including thermal
limiters and the isolating relay.
Note: The isolating relay is only energized when an oven mode is selected.
5. If the wiring continuity is good, then it is likely that the oven cavity fan is not faulty.
(refer to Symptom Procedure Checklist for further component tests)
If the oven cavity fan will not turn off
1. Replace the power module if no other component faults can be found, the cooling fan
relay may be faulty. (refer to Servicing Instructions Section 7.9)

5.21 Tracing oven light faults

(Refer to Technical Overview Section 2.17)
PROCEDURE:
If light bulb is faulty
1. Replace halogen bulb. (refer to Servicing Instructions Section 7.13)
If all the lights will not turn on or replacing the bulb/s did not fix the problem.
1. Check the continuity of the light wiring back to power module. (refer to Technical
Overview Section 2.25 for light connector location)
Replace the lamp assembly if there is no continuity.
Instructions Section 7.14)
2. Check power module light connector for 12
Technical Overview Section 2.25)
Replace the lamp assembly if 12

3. If there is not 12
transformers and correct power supply from the switchboard.
Replace the power module if the transformers and supply power voltages are
correct. (refer to Servicing Instructions Section 7.9)
Note: If the wiring continuity is good and 12
lights are not faulty. (refer to Symptom Procedure Checklist for further component
tests)
If the lights do not turn off
1. Check to see if the door switch is faulty by selecting an Aero Oven Mode and leaving
the door open. If the oven cavity fan starts after eight seconds, the switch is faulty.
If the faulty door switch cannot be easily repaired, replace the door lock assembly.
