(2) If the fault continues:
- do a check of the PUSHBUTTON SWITCH-AIR COND/PACK 1 (7HB) and replace it if necessary (Ref. ASM 21-51/02).
(3) If the fault continues:
- do a check of the BOARD-ANN LT TEST & INTFC (8LP) and replace it if necessary (Ref. ASM 21-51/02).
(4) If the fault continues:
- replace the CONTROLLER-PACK 1 TEMP (7HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).
(5) If the fault continues:
- do a check and repair the wiring between: RELAY (8LP) connector A/30 and SW (7HB) connector A/7, RELAY (8LP) connector A/41 and GND, RELAY (8LP) connector A/27 and PC 1 (7HH) connector AB/7A RELAY (8LP) connector A/27 and RELAY (15HB) connector B/A2, RELAY (8LP) connector A/29 and CB (1HB) (Ref. ASM 21-51/02).
R **ON A/C 401-499,
D. If the test gives the maintenance message TEST OK, but the FAULT legend on the pushbutton switch AIR COND/PACK 1, which is installed on the panel 30VU, comes on:
- do the operational test of the annunciator light test system (Ref. AMM TASK 33-14-00-710-001).
(1) If the test gives a different maintenance message refer to the Fault Symptom List.
(2) If the fault continues:
- do a check of the PUSHBUTTON SWITCH-AIR COND/PACK 1 (7HB) and replace it if necessary (Ref. ASM 21-51/02).
(3) If the fault continues:
- do a check of the BOARD-ANN LT TEST & INTFC (8LP) and replace it if necessary (Ref. ASM 21-51/02).

(4) If the fault continues:
- replace the CONT-AIR COND SYSTEM 1 (47HH) (Ref. AMM TASK 21-61-34-000-002) and (Ref. AMM TASK 21-61-34-400-002).
(5) If the fault continues:
- do a check and repair the wiring (Ref. ASM 2151S02) from:
- the RELAY (8LP)A pin 30 and the SW (7HB)A pin 7,
- the RELAY (8LP)A pin 41 and ground,
- the RELAY (8LP)A pin 27 and the ACSC1 (47HH),
- the RELAY (8LP)A pin 27 and the RELAY (15HB)B pin A2 and,
- the RELAY (8LP)A pin 29 and the CB (1HB).
