Check the connectors CN4, CN1 in outdoor PCBs 

Is  connection  to  connector  good?  Whether  the  input 
voltage range is 220-240V? 

Is the wires to compressor right 

Unplug the wiring to compressor, 
then restart, whether display the

Check compressor 

Turn  on  the  unit  in  cooling  or  heating  in  different  season,  use  a 

frequency meter to test the frequency in one of the three wires to 

compressor, if there is frequency in wires, but compressor do not 

run, the compressor is defective. 

Between U, V, W three terminals, the resistance is ~1
