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.
