8. Check Procedures
8.1 Temperature Sensor Check
WARNING
Be sure to turn off all power supplies or disconnect all wires to avoid electric shock.
Operate after compressor and coil have returned to normal temperature to avoid risk of injury.
1. Disconnect the temperature sensor from PCB (Refer to Chapter 5 & 6, "Indoor & Outdoor Unit Disassembly").
2. Measure the resistance value of the sensor using a multi-meter.
3. Check corresponding temperature sensor resistance value table (Refer to Chapter 8. Appendix).
Note: The picture and the value are only for reference, actual condition and specific value may vary.
8.2 Compressor Check
1. Disconnect the compressor power cord from outdoor PCB (Refer to Chapter 6, "Outdoor Unit Disassembly").
