Compressor Components
3.19.3 Verification
1. Isolate compressor power.
2. Remove the Service Side Cover, verifying the
LEDs on the Backplane have turned off.
3. Disconnect the Cavity Temperature Sensor
Cable, J23, from the Backplane.
4. Set multimeter for resistance measurements.
5. Measure the resistance between the Cavity
Temperature Sensor terminals 1 and 3. See Figure
90 (Cavity Temperature Sensor Terminal).
• The Cavity Temperature Sensor is a 10KΩ @
77°F (25°C) NTC thermistor. The resistance value
should correspond to Figure 91 (Temperature vs.
Resistance).
6. Measure the resistance of the Cavity
Temperature Sensor terminals 1 and 3 to ground.
See Figure 90 (Cavity Temperature Sensor
Terminal).
• The resistance value should be open or infinite.
