Temperature sensor
checking
Disconnect the temperature sensor from PCB, measure the resistance value with a tester.
Temperature Sensors
Room temp.(T1) sensor,
Indoor coil temp.(T2) sensor,
Outdoor coil temp.(T3) sensor,
Outdoor ambient temp.(T4) sensor,
Compressor discharge temp.(T5) sensor .
Measure the resistance value of each winding by using the multi--meter.
