Firstly display P0. 1 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. 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 refrigerant if 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 of stop. 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.
