ADDITIONAL INFORMATION FOR CRITICAL PARTS:
Temperature sensor troubleshooting
Disconnect the temperature sensor from the PCB, and measure the resistance value with a multimeter.
Temperature sensors:
1.
Room temperature (T1) sensor,
2.
Indoor coil temperature (T2) sensor,
3.
Outdoor coil temperature (T3) sensor,
4.
Outdoor ambient temperature (T4) sensor,
5.
Compressor discharge temperature (T5) sensor
Indoor Fan Motor
Measure the resistance value of each winding by using the multimeter.
