 (4)  S 976-004Measure the resistance from pin 23 to pin 24 on connector D454 for the temperature controller (WDM 21-61-01).
 (5)  S 976-005Find the temperature on Figure 601 that is nearest to the temperature that you wrote down.
 (6)  S 976-006Compare the permitted range of resistance for that temperature to the resistance you wrote down.
 (7)  S 026-007If the resistance is out of range, replace the sensor (AMM 21-61-61/401).
 (8)  S 416-008Install the temperature controller (AMM 21-61-81/401).
