Improper setting of temperature

Whether cooling (heating) load
is proper

Adjust the set temperature

Check the estimated load of cooling (heating)

Leakage or shortage of refrigerant

Leakage occurs between high and 
low pressure inside compressor

Malfunction of four-way valve

Partial blockage of capillary

Blockage of cooling system

Replace the compressor

Replace the four-way valve

Replace the capillary

Use the method of observing condensation 
on the evaporator and pressure value of
high pressure manometer to see whether 
the system is blocked and carry out 
corresponding handling on the system

Vacuumize after leakage detection 
and leakage repair. Charge refrigerant 
according to specification.

Malfunction of 
refrigerant flow

Poor thermal insulation of connecting 
pipe of indoor and outdoor unit

Ensure that both thick pipe and thin pipe are insulated 
well. The exposed part of the connector and copper pipe 
must be insulated as well.

Heat exchanger of outdoor unit 
is blocked

Air filters are blocked

Fan speed is set too slow

Fan speed turns low

Improper installation location 
for outdoor unit

Outdoor unit should be installed in a 

place with well ventilation

Set the fan speed to high or medium 
speed

Clean the filter

Clean the dust accumulated on the 
surface of the heat exchanger

Air circulation 
is insufficient

Damage of

capacitor 

damaged

Damage of 

motor

Replace the

capacitor

Replace the motor

Flashing or awning can be installed appropriately. If the 

max. cooling capacity cannot be satisfied, replacement of 

the air conditioner is recommended.

Maintain a certain degree of indoor sealability. Try not to 
use appliance with high amount of heat.

Outdoor temperature is too high

Indoor sealability is inadequate; too many 
people go in and out frequently; there is 
heating unit in the room.

Poor cooling
