(3) If the fault continues:
- do a check that the resistance of the FWD cabin-temperature sensor (22HK) measured between connector A/A and A/B and connector A/E and A/D is in these limits (Ref. ASM 21-63/03): Temp (Deg.C) OHMS ---------------------------
+ 10 18820 +/- 5 %
+ 18 13340 +/- 5 %
+ 25 10000 +/- 5 %
+ 30 8197 +/- 5 %
+ 40 5598 +/- 5 %
+ 50 3903 +/- 5 %
(a) If the resistance values are out of the specified limits:
- replace the SENSOR-TEMPERATURE, FWD CABIN (22HK) (Ref. AMM TASK 21-63-17-000-001) and (Ref. AMM TASK 21-63-17-400-001).
(4) If the fault continues:
- do a potentiometer test of the FWD cabin-temperature selector (28HK) (Ref. CMM 216312).
(a) If the test is not OK:
- replace the SEL-TEMPERATURE, AIR COND/FWD CABIN (28HK) (Ref. AMM TASK 21-63-11-000-001) and (Ref. AMM TASK 21-63-11-400-001).
(5) 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).
(6) If the fault continues:
- replace the CONT-AIR COND SYSTEM 2 (57HH) (Ref. AMM TASK 21-61-34-000-002) and (Ref. AMM TASK 21-61-34-400-002).
D. If the test confirms the fault for the AFT cabin zone, with the pushbutton switch HOT AIR, which is installed on the panel 30VU, set to on (with FAULT and OFF legends off) or OFF:
- do a check that the resistance of the AFT cabin-duct temperature sensor (17HK) measured between connector A/E and A/F and connector A/C and A/D is in these limits (Ref. ASM 21-63/03):
Temp (Deg.C) OHMS ---------------------------
+ 10 18820 +/- 5 %
+ 18 13340 +/- 5 %
+ 25 10000 +/- 5 %
+ 30 8197 +/- 5 %
+ 40 5598 +/- 5 %
+ 50 3903 +/- 5 %
(1) If the resistance values are out of the specified limits:
- replace the SENSOR-DUCT TEMPERATURE,AFT CABIN (17HK) (Ref. AMM TASK 21-63-15-000-001) and (Ref. AMM TASK 21-63-15-400-001).
R (2) If the fault continues:
R - do a check that the AFT cabin-temperature sensor (23HK), housing,
R ducts and flexible hoses are free from contamination, are not
R damaged and that the sense line has no leakage (Ref. AMM TASK 21-R 63-17-210-001).
R (3) If the fault continues:
R - do a check that the resistance of the AFT cabin-temperature sensor
R (23HK) measured between connector A/A and A/B and connector A/E and
R A/D is in these limits (Ref. ASM 21-63/03):
R Temp (Deg.C) OHMS
R ---------------------------R + 10 18820 +/- 5 %
R + 18 13340 +/- 5 %
R + 25 10000 +/- 5 %
R + 30 8197 +/- 5 %
R + 40 5598 +/- 5 %
R + 50 3903 +/- 5 %
R (a) If the resistance values are out of the specified limits:
R - replace the SENSOR-TEMPERATURE, AFT CABIN (23HK) (Ref. AMM TASK
R 21-63-17-000-001) and (Ref. AMM TASK 21-63-17-400-001).
R (4) If the fault continues:
R - do a potentiometer test of the AFT cabin-temperature selector
R (29HK) (Ref. CMM 216312).
R (a) If the test is not OK:
R - replace the SEL-TEMPERATURE, AIR COND/AFT CABIN (29HK) (Ref.
R AMM TASK 21-63-11-000-001) and (Ref. AMM TASK 21-63-11-400-R 001).
R (5) If the fault continues:
R - replace the CONT-AIR COND SYSTEM 1 (47HH) (Ref. AMM TASK 21-61-34-R 000-002) and (Ref. AMM TASK 21-61-34-400-002).
R (6) If the fault continues:
R - replace the CONT-AIR COND SYSTEM 2 (57HH) (Ref. AMM TASK 21-61-34-R 000-002) and (Ref. AMM TASK 21-61-34-400-002).
