Technical Information

9.3 MAINTENANCE METHOD FOR NORMAL MALFUNCTION

1. Air Conditioner Cant be Started Up

Possible Causes

Discriminating Method

(Air conditioner Status)

Troubleshooting

No power supply, or poor connection for
power plug

After energization, operation indicator isnt
bright and the buzzer cant give out sound

Confirm whether its due to power failure. If yes, wait for
power recovery. If not, check power supply circuit and make
sure the power plug is connected well.

Wrong wire connection between indoor
unit and outdoor unit, or poor connection
for wiring terminals

Under normal power supply circumstances,
operation indicator isnt bright after
energization

Check the circuit according to circuit diagram and connect
wires correctly. Make sure all wiring terminals are connected
firmly

Electric leakage for air conditioner

After energization, room circuit breaker trips
off at once

Make sure the air conditioner is grounded reliably
Make sure wires of air conditioner is connected correctly
Check the wiring inside air conditioner. Check whether the
insulation layer of power cord is damaged; if yes, place the
power cord.

Model selection for air switch is improper

After energization, air switch trips off

Select proper air switch

Malfunction of remote controller

After energization, operation indicator is
bright, while no display on remote controller or
buttons have no action.

Replace batteries for remote controller Repair or replace
remote controller

2. Poor Cooling (Heating) for Air Conditioner

Possible Causes

Discriminating Method

(Air conditioner Status)

Troubleshooting

Set temperature is improper

Observe the set temperature on remote
controller

Adjust the set temperatur

Rotation speed of the IDU fan motor is set
too low

Small wind blow

Set the fan speed at high or medium

Filter of indoor unit is blocked

Check the filter to see its blocked

Clean the filter

Installation position for indoor unit and
outdoor unit is improper

Check whether the installation postion is
proper according to installation requirement
for air conditioner

Adjust the installation position, and install the rainproof and
sunproof for outdoor unit

Refrigerant is leaking

Discharged air temperature during cooling
is higher than normal discharged wind
temperature; Discharged air temperature
during heating is lower than normal discharged
wind temperature; Units pressure is much
lower than regulated range

Find out the leakage causes and deal with it. Add
refrigerant.

Malfunction of 4-way valve

Blow cold wind during heating

Replace the 4-way valve

Malfunction of capillary

Discharged air temperature during cooling
is higher than normal discharged wind
temperature; Discharged air temperature
during heating is lower than normal discharged
wind temperature; Unitt pressure is much
lower than regulated range. If refrigerant isnt
leaking, part of capillary is blocked

Replace the capillary

Flow volume of valve is insufficient

The pressure of valves is much lower than that
stated in the specification

Open the valve completely

Malfunction of horizontal louver

Horizontal louver cant swing

Refer to point 3 of maintenance method for details

Malfunction of the IDU fan motor

The IDU fan motor can’t operate

Refer to troubleshooting for H6 for maintenance method in
details

Malfunction of the ODU fan motor

The ODU fan motor can’t operate

Refer to point 4 of maintenance method for details

Malfunction of compressor

Compressor cant operate

Refer to point 5 of maintenance method for details

3. Horizontal Louver Cant Swing

Possible Causes

Discriminating Method

(Air conditioner Status)

Troubleshooting

Wrong wire connection, or poor connection

Check the wiring status according to circuit
diagram

Connect wires according to wiring diagram to make sure all
wiring terminals are connected firmly

Stepping motor is damaged

Stepping motor cant operate

Repair or replace stepping motor

Main board is damaged

Others are all normal, while horizontal louver
cant operate

Replace the main board with the same model
