Fault

 

 

 

 

Cause Analysis

 

 

 

 

 

 

 

Air conditioner does not run.

 

Power failure?

 

 

 

 

• Circuit protection device tripped?

 

 

 

• The voltage is too high or too low?

 

 

 

 

(

Refer to Page 15). (To be tested by

 

 

 

professional technicians).

 

 

 

• Timer function is correctly used?

 

 

 

 

(

Refer to Page 7).

 

 

 

 

 

 

Air conditioner is poor in cooling (or heating) effect.

 

Is temperature setting proper? (

Refer to Page 7)

 

 

• Is the air inlet or outlet of outdoor unit blocked?

 

 

Is the air filter clogged by dust? (

Refer to Page

 

 

 

10).

 

 

 

 

• Are all doors and windows closed?

 

 

 

• Is air flow set to “LOW FAN”?

 

 

 

• Is any other heating source in the room?

 

 

 

 

Remote control cannot execute control.

 

Remote control sometimes cannot execute control if

 

 

 

the air conditioner is subject to abnormal interference

 

 

 

or frequent switching of functions. To resume normal

 

 

 

operation, just pull out the battery and reinsert it

 

 

 

properly.

 

 

 

 

• Is remote within receivable range or blocked by any

 

 

 

obstacles? (

Refer to Page 7)

 

 

 

• Check the battery in remote control for power level.

 

 

 

If low power, replace the battery. (

Refer to Page

 

 

 

9)

 

 

 

 

 

• Is the remote control is damaged.

 

 

 

 

 

Water leaks from indoor unit.

 

Room air humidity is excessively high.

 

 

Condensation water overflowing.

 

 

 

• Connection of indoor unit drain pipe is leaking.

 

 

 

 

Water leaks from outdoor unit.

 

Under cooling mode, water might condense on pipe

 

 

 

or pipe joint due to cooling.

 

 

 

• Defrosted water flows out under heating or defrost

 

 

 

(auto defrost) mode.

 

 

 

• Under cooling mode, water attached on heat

 

 

 

exchanger will drip.

 

 

 

 

 

Indoor unit has unusual noise.

 

 

• The sound that the fan or compressor relay is

 

 

 

 

switching (close/open).

 

 

 

 

• Air conditioner may give out sounds under defrost

 

 

 

 

or when it is stopped. This is caused due to inverse

 

 

 

 

flow of refrigerant in the unit.
