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.
