Sensor DTS Reinstallation

The Defrost Temperature Sensor (DTS) must have insulating material placed completely over the sensor to ensure
the coil metal temperature is sensed.
7.28.6

Sensor ETS1 and ETS2 Reinstallation

The Evaporator Temperature Sensors, ETS1 and ETS2 are located in a tube holder under insulation, as illustrated
in Figure 7.24. 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.
2. Verify that the Start-Stop switch (ST) is in the "0" position.
3. Remove the existing sensor.
4. Clean all silicone sealer and dielectric compound from the sensor well. Make sure that the well is clean and
dry. The top of the compressor, where the sensor seals, must also be clean and dry.
5. Using the syringe supplied with the replacement sensor, squeeze all of the dielectric compound into the sen-
sor well.
6. Place a bead of the silicone sealer supplied with the replacement sensor around the sensor sealing ring.
Insert sensor into the well with the leads parallel to the suction fitting.
7. Reconnect the sensor (see
T-362
