The motor of outdoor fan is damaged
Wrong wire connection
The capacitor of outdoor fan is damaged
There's malfunctionfor for the compressor
Compressor's running capacitor is broken
The voltage is low or high
Wrong wire connection
There's malfunction for protector

Replace the fan motor or the defective parts
Replace the fan motor
Connect the wire correctly basing on the circuit
drawing
Replace the fan capacitor with the same mode
and specification
Replace the fan motor
Connect the wire correctly basing on the circuit
drawing
Replace the fan capacitor
Replace the compressor
Replace the capacitor
Suggesting to equip with the manostat
Connect the wire correctly basing on the circuit
drawing
Use the multimeter to check whether the contact point of
the compressor is conducted at the time of not subheating.
If it isn't conducted, please replace the protector.
Adjust the volume of the refrigerant
Replace the capillary
Replace the compressor
Replace the protector
Check the wire connection. If the wire connection
