A. If the test gives the maintenance message RECIRC FAN 1 OR SPLY:
- 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 PUSHBUTTON SWITCH-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 SUPPRESSION (16HG) and replace it if necessary (Ref. ASM 21-21/01). 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 AIR CONDITIONING 空调1(51)
