Detach the assembled sensor from the PCB sensor

connector and measure the sensor resistance with

ohmmeter(tester)

Replace the sensor

Sensor resistance value : 20°C- 6.0836kohm

30°C - 4.1331kohm

35°C -3.4352kohm

40°C- 2.8699kohm

Connect the sensor to PCB connector (4pin in)

supply power and measure the voltage of the

connector accordingly

Below 0.5V or Over 4.5V

Replace the PCB

NO

Re-energize and check the protection code on display. Firstly display P0.

1 If this code is displayed when the compressor is started for several seconds or even not started, checkthe compressor connection for correctness, if no insert wrong, replace outdoor PCB.

2 Check if the outdoor module is tightly installed onto the radiating fins and if the silicone is applied evenly,fix the screws again if loose.

3 Check the system pressure, recharge refrigerant if the pressure is low, and discharge some refrigerantif the pressure is too high. 4 Check the outdoor ventilation and if there is any obstruction that affects the normal radiating of the air

conditioner, and installation again.5 If the above inspections are normal, but the fault remains unsolved, please replace the outdoor PCB.

Re-energize and check the protection code on display. Firstly display P9.a) Check the U,V, W connection, if is correctness or loose please connect again.b) If this code is displayed when the compressor is started for several seconds or even not started,

check the compressor connection for correctness, if no insert wrong, replace outdoor PCB.c) When the compressor is restarted immediately after stop, this might also cause P9 protection

because the cooling system is not stable, try starting the air conditioner again after a longer period ofstop.

The wiring U,V,W are closed as red, white and blue respectively.

Heat radiation problem easily happened while the screw is not fixed tightly.
