Is the voltage between terminal "N" and" 3 " of the terminal board in the outdoor unit the power supply voltage ? YES
NO
YES
Is the voltage between terminal "N" and " 0 " of RY4 in the outdoor unit the power supply voltage ? NO
Measure resistances of TH1 and TH2.
Replace the PWB ass'y with a new one.
Replace the relay RY4 in the outdoor unit with a new one. Are the resistances conformed Fig. 1 ? NO
YES
Replace the thermistor ass'y with a new one.
The control circuit is normal. The compressor may be defective. The running capacitor may be defective. Refrigerant may be leaked. The outdoor fan motor may be defective. The outdoor fan motor capacitor may be defective.
