(4) If the fault continues:
- do a potentiometer test of the AFT cabin-temperature selector (29HK) (Ref. CMM 216312).
(a) If the test is not OK:
- replace the SEL-TEMPERATURE, AIR COND/AFT CABIN (29HK) (Ref. AMM TASK 21-63-11-000-001) and (Ref. AMM TASK 21-63-11-400-001).

B. If the test confirms the fault for the cockpit zone, with the pushbutton switch HOT AIR, which is installed on the panel 30VU, set to on (with the FAULT and OFF legends off) or OFF:
- do a check that the resistance of the cockpit-duct temperature sensor (15HK) measured between connector A/E and A/F and connector A/C and A/D is in these limits (Ref. ASM 21-63/03):
