FAQs

• What is the average life span of a residential air conditioner?

  Generally, the average life span of any air conditioner is six to seven years. This is subjected to usage pattern and regular servicing of the air conditioner by a qualified air conditioner technician.

• What is an Inverter air conditioner? Is this more efficient than a non-Inverter conventional air conditioner?

  An Inverter air conditioner delivers cool air by varying the frequency of the compressor, and thus regulates the refrigerant to satisfy room cooling requirements and achieve the desired temperature with minimal fluctuations. It eliminates waste with precise control. In this way, it is more energy efficient.

Room Air Conditioners (Home Air Conditioners)

• The air conditioner does not start operation immediately after it is turned on.

  To reduce excessive load in a restart, the air conditioner does not operate for three minutes when the ON switch is pressed immediately after it is shut down or when the operation mode (setting) is changed using the remote controller.

• The air conditioner does not blow air immediately after it starts operation in the heating mode.

  The air conditioner conducts a "warm-up" operation first so that it won't blow cold air in the heating mode. The fan starts operating after one to four minutes of warm-up operation. (The warm-up operation becomes longer when the outside air temperature is low.)

• The air conditioner produces a water flowing sound.

  The water flowing sound is produced by the refrigerant that flows inside the air conditioner. This sound is more prone to generation when the defrost operation is activated in a heating operation.

• The air conditioner produces an air releasing sound.

  The air releasing sound is caused by a change of the refrigerant flow direction. This sound is generated when the air conditioner stops operating or the defrosting operation is activated in a heating operation.

• The air condition produces a crackling sound.

  Plastic parts such as the front panel produces a crackling sound when they expand or contract slightly due to temperature change.

• The outdoor unit discharges water or steam.

  The defrost operation activated in the heating mode removes frost, which turns into water or steam. A small amount of water is also discharged during a heating operation.

• The amount of drained water is large (as compared to the amount discharged in the previous year or the day before).

  The amount of drained water varies depending on room temperature and humidity. A large amount of drained water does not denote a malfunction.

• The air conditioner does not operate (Operation lamp is not lit).

  Check the following:

  • Make sure the circuit breaker is not turned off and the fuse is not blown.
  • Make sure the power cord plug is connected securely to the service outlet.
  • Make sure there is no power outage.
  • Make sure the remote controller has new batteries.
  • Make sure the timer is not programmed mistakenly.

• The air conditioner does not cool or warm the room.

  Check the following.

  • Make sure the air filters are not dirty.
  • Make sure the air inlets and outlets of the indoor and outdoor units are not blocked by objects.
  • Make sure the temperature setting on the remote controller is appropriate.
  • Make sure the doors and windows are closed.
  • Make sure the air flow and direction settings are appropriate.
  • Make sure ventilation fans in the room are not operating.

• The air conditioner stops operating (Operation lamp blinks).

  • Check to see if the air filters are clean.
  • Also make sure the air inlets and outlets of the indoor and outdoor units are not blocked.

• The air conditioner operates abnormally.

  Lightning and radiowaves can sometimes cause abnormal operations of air conditioners.

  Cut off the power supply by unplugging the power cord or turning off the circuit breaker, then re-supply power and restart the air conditioner.

• The indoor unit produces a mist.

  The cold air blow out during a cooling operation reduces the temperature of the room air and sometimes generates a mist.

• The air conditioner stops operation (Operation lamp remains lit).

  When power supply voltage fluctuates largely, the air conditioner may stop operating to protect the equipment. (When power supply returns to a normal condition, the air conditioner resumes operation after three minutes.)

• The air conditioner stops in the middle of operation (ON timer in operation).

  When the ON timer is set, the air conditioner may start as early as one hour before the set time in order to bring the room temperature close to the temperature set with the remote controller.

  If the remote controller is operated (except ON/OFF operation) during this time period, the air conditioner enters the stop mode.

  When this happens, turn on the air conditioner using the remote controller, and set the timer again.

• After the power switch is turned on, the air outlet flaps operate.

  When the unit is turned on, the microcomputer operates the flaps to determine their position for initialization.

• When the operation mode is changed, the air outlet flap position also changes.

  The flap control varies the flap position depending on the operation mode such as cooling and heating.

• The air flow suddenly becomes stronger during a heating operation.

  When the air flow is set to LOW, the amount of air flow increases when the overload control is activated.

  ("Overload" is a condition in which the air conditioner operates under excess load. Overload can be caused by dirty filters.)

• The air outlet flaps sometimes operate during a cooling operation.

  The air outlet flaps move when the frost prevention or ceiling soiling prevention function is activated.

• In the microcomputer-controlled dry mode

  The indoor unit fan operates at L for one minute when the outdoor unit (compressor) is not operating. The monitoring function forcibly operates the indoor unit fan for one minute.

• The air outlet flaps do not operate

  At the same time in the master and slave indoor units of a simultaneous operation multi-unit. There is a slight time lag in the signal transmission between the master and slave units. It does not denote a malfunction.

• The indoor unit fan operates after a heating operation stops (in an air conditioner equipped with a heater).

  In order to reduce the temperature of the heater, the fan operates 60 to 100 seconds after the air conditioner stops operating.

• The drain pump continues operating after a cooling operation stops.

  After the air conditioner stops operating, the drain pump operates for several minutes in order to discharge condensate from the drain pan (condensate receiving tray).

• When the air outlet swing function is set to ON, the flaps remain at a horizontal position.

  The flaps remain at the same position when room temperature reaches the set level and the thermostat turns off. When the thermostat is off, the flaps do not swing.

• The remote control thermostat cannot be set.

  When a multiple number of units are controlled by a single remote controller (group control), the remote control thermostat cannot be set.

• The air conditioner produces an unpleasant odor.

  Room, furniture and cigarette smoke odors enter the indoor unit and remain in the unit. When the air conditioner is turned on, it blows the accumulated odors together with air. (It is recommended to clean the inside of the indoor unit. Call the contact center.)

  • The power cord and plug are extremely hot or damaged.
  • Abnormal noise is produced during operation.
  • Foreign items or water entered the air conditioner accidentally.
  • Circuit breaker, fuse or earth leakage circuit breaker trips frequently.
  • The ON switch or button sometimes fails to operate the air conditioner.
  • Burning odors are produced.
  • Water leaks from the indoor unit.
  • The Operation lamp blinks, and the temperature indicator displays two alphanumeric characters.
    (The display indicates the type of error. Check the alphanumeric characters and notify your dealer when requesting a repair.)
