R 1_ If the voltage is correct:
R - replace the VALVE-ANTI-ICE (37HH) (Ref. AMM TASK 21-61-41-R 000-001) and (Ref. AMM TASK 21-61-41-400-001).
R 2_ If the voltage is not correct:
R - do a check and repair the wiring (Ref. ASM 2161S02) from:
R - the VALVE (37HH)A pin A to the ACSC2 (57HH) and,
R - the VALVE (37HH) to ground.
R (6) If the fault continues:
R (a) Do a check of the reheater (11HM3) for contamination (Ref. AMM TASK 21-52-00-780-001).

____ R with the P/N 755A0000-04 and previous. R It is not applicable to reheaters with the P/NIs R 755A0000-04 Amendment A or subsequent.
R (b) If the reheater is clogged: R - do the cleaning of the clogged reheater (11HM3) (Ref. AMM TASK 21-52-00-100-002),
R (7) If the fault continues: R - do the cleaning of the clogged condenser (11HM2) (Ref. AMM TASK 21-52-00-100-003),
R (8) If the fault continues:
R - do a check of the position of the manual override lever of the pack
R 2 flow control-system (24HB).
R (a) If the valve is not fully open:
R - replace the FLOW CONTROL SYSTEM (24HB) (Ref. AMM TASK 21-51-51-R 000-001) and (Ref. AMM TASK 21-51-51-400-001).

R (9) If the fault continues:
R - do a check of the water drain line between the extractor (11HM8)
R and the injector (21HM) and the injector nozzle (21HM) for
R contamination and clean it if necessary (Ref. AMM TASK 21-52-16-R 000-001), (Ref. AMM TASK 21-52-16-400-001), (Ref. AMM TASK 21-52-R 42-000-001) and (Ref. AMM TASK 21-52-42-400-001).
