A. If the oven does not operate during the test:
Subtask 25-35-00-810-053-C ** ON A/C NOT FOR ALL - Replace the oven AMM 25-35-19-000-001 and AMM 25-35-19-400-001.
- Do a check and, if necessary, repair the wiring between the related galley control panel and the electrical connector of the oven .
- Do a check and, if necessary, repair the
related circuit breaker(s) at the galley control panel and, if installed, the related relays or switches ASM 253101, ASM 253201 and ASM 253301.
- Do a check and, if necessary, repair the wiring of the galley (Ref. TSM TASK 24-56-00-810-801).
A. If the oven does not operate during the test:
Subtask 25-35-00-710-057-A - Replace the Oven Control Module (OCM) AMM 25-35-19-000-004 AMM 25-35-19-400-004.
NOTE: A temporarily installed oven that operates correctly helps to make sure that the OCM is defective.
(1) If the fault continues:- Replace the oven AMM 25-35-19-000-001 and AMM 25-35-19-400-001.
NOTE: A temporarily installed OCM that operates correctly helps to make sure that the oven is defective.
(2) If the fault continues:- Do a check and if necessary repair the wiring between the related power supply terminal block and the electrical connector of the oven .
- Do a check and if necessary repair the related CB at the galley control panel and if installed, the related relays or switches in the galley ASM 253101 or ASM 253201 or ASM 253301.
- Do a check and if necessary repair the wiring of the galley power supply (Ref. TSM TASK 24-56-00-810-801).
