Figure 4-272 Pressure/Temperature Sensor Locations (TTH/TGH)
The sensor connector clips link to the compressor control cable which then connect to the Backplane at J18 and J19
(and J17 for TTH/TGH only).
4.32.3 Pressure/Temperature Sensor Verification
1. Isolate the compressor power as described in Section 1.8 Electrical Isolation on page 22.
2. Remove the Service Side Cover. Refer to Section 4.1.3.1 Service Side Cover Removal and Installation on
3. Disconnect the pressure/temperature cable clip (SUCTION – J18 or DISCHGE – J19 or INTER - J17) from
the Backplane board. Refer to Figure 4-274 Pressure/Temperature Cable Terminals on page 247 for this
and the following step.
4. Using a multimeter set for resistance measurements, place leads on Terminal 1 and Terminal 2 of the
pressure/temperature cable clip.
l
The temperature sensor is a 10KΩ @ 77°F (25°C) NTC thermistor. The resistance value should
correspond to Figure 4-273 Temperature vs. Resistance.
