A. If the test gives the maintenance message RECIRC FAN 1 OR SPLY(15HG):
- make sure that the recirculation filter (4012HM) housing and the adjacent area is clean.
- remove the FILTER-RECIRCULATION (4012HM) (Ref. AMM TASK 21-21-41-000-001).
(1) If the recirculation fan (15HG) operates correctly:
- do a check of the recirculation filter (4012HM) for contamination.
(a) If the filter is clogged:
- replace the FILTER-RECIRCULATION (4012HM) (Ref. AMM TASK 21-21-41-000-001) and (Ref. AMM TASK 21-21-41-400-001).
(b) If the filter is not clogged:
- install the FILTER-RECIRCULATION (4012HM) (Ref. AMM TASK 21-21-41-400-001).
(2) If the recirculation fan (15HG) does not operate:
- do a check of the P/BSW-VENTILATION/CAB FANS (4HG) and replace it if necessary (Ref. ASM 21-21/01).
(a) If the fault continues:
- do a check of the RELAY-FAN FAULT SUPPRESS (16HG) and replace it if necessary (Ref. ASM 21-21/01).
(b) If the fault continues:
- do a check of the RELAY-L FAN POWER (5HG) and replace it if necessary (Ref. ASM 21-21/01).
(c) If the fault continues:
- do a check of the RELAY-L FAN CONTROL (7HG) and replace it if necessary (Ref. ASM 21-21/01).
(d) If the fault continues:
- do a check of the RELAY-L FAN FAULT (10HG) and replace it if necessary (Ref. ASM 21-21/01).
(e) If the fault continues:
- replace the FAN RECIRCULATION (15HG) (Ref. AMM TASK 21-21-51-000-001) and (Ref. AMM TASK 21-21-51-400-001).
