Does compressor active ? Does it go off immediately after active ?1. Is the discharge outlet of the outdoor unit clogged ? 2. Is the power supply voltage at least 198 V at full power operation ? 3. Check for refrigerant leaks at the tubing connections. 4. Measure the resistance of compressor thermistor TH1 on the 5. Measure the resistance of heat exchanger pipe thermistor TH2 on 1. Check the circuit in the power transistor module. 2. Is the outdoor fan revolving ?1. Measure the resistance of thermistor TH2 on the outdoor unit (see Figure 2).1. Are the connectors of the outdoor unit thermistors well attached ? 2. Measure the resistance of thermistors TH1 and TH2 on the 1. Can voltage be detected at the current transformer on the outdoor 1. Is the discharge outlet of the outdoor unit clogged ?1. CHeck wiring of power factor module.1. Is the fan motor locked ? 2. Is the wiring connector firmly fitted ? 3.
