7.24.4 Sensors RRS and RTS Reinstallation
Reinstall the return sensor (see
enlarged positioning section of the sensor against the side of the mounting clamp.

7.24.5

Sensor DTS Reinstallation

The Defrost Temperature Sensor (DTS) sensor must have insulating material placed completely over the sensor to
ensure the coil metal temperature is sensed.
Sensors ETS1 and ETS2
The Evaporator Temperature Sensors (ETS1 and ETS2) are located in a tube holder under insulation (see
7.21). When the combo sensor is removed and reinstalled, it must be placed in a tube holder by applying thermal
grease. Insulating material must completely cover the sensor to ensure the correct temperature is sensed.

Sensor CPDS Reinstallation

To replace the Compressor Discharge Temperature Sensor (see
1. Ensure the unit is disconnected from the power source and that ST is in OFF position.
2. Remove the existing sensor. Clean all silicone sealer and dielectric compound from the sensor well. Ensure
well is clean and dry. The top of the compressor, where the sensor seals, must also be clean and dry.
