Temperature Sensor
Feed Through
The Stator temperature sensor feed through passes the reading of the Stator temperature thermistors
to the CCM for conversion to a digital signal used to determine actual motor winding temperature,
while keeping refrigerant pressure from escaping.
Removal:
1. Isolate the Compressor power as described in the “Electrical Isolation of the Compressor/VFD”
section of this manual.
2. Isolate the compressor and recover refrigerant.
3. Remove the Service Side Cover (Refer to the “Service Side” section in this manual).
4. Disconnect the Stator temperature sensor cable from CCM J12.
5. Remove the Stator temperature sensor cable from the feed through.
6. Remove the Service Electronics Assembly. Refer to the “VTT Service Electronics Assembly”
section in this manual.
7. Refer to the “Rear Bearings” section of this manual regarding access to the internal connector.
8. Remove the fasteners holding the Stator Temperature Sensor Feed Through to the housing.
9. Disconnect the Stator Temperature Sensor Feed Through wire from the internal connector.
10. Carefully remove the Stator Temperature Sensor Feed Through from the housing.
