Troubleshooting
Refer to the following chart if the air conditioner operates abnormally. This may save time and unnecessary expense.
| Problem Solution | |
| The air conditioner does not operate at all. | Check if the power plug is properly connected.Check whether the auxiliary power switch (MCCB, ELB) is turned on.If the auxiliary power switch (MCCB, ELB) is turned off, the air conditioner does not work although you press the ⏻ (Power) button.When you clean the air conditioner or do not use it for an extended period of time, turn off the auxiliary power switch (MCCB, ELB).After the air conditioner is not used for an extended period of time, be sure to turn on the auxiliary power switch (MCCB, ELB) 6 hours before starting operation.NOTEThe auxiliary power switch (MCCB, ELB) is sold separately.Make sure that auxiliary power switch (MCCB, ELB) is installed in the distribution box inside the building.If the air conditioner is turned off by the Timed off function, turn on the air conditioner again by pressing the ⏻ (Power) button. |
| The temperature does not change. | Check whether the Fan mode is running. In the Fan mode, the air conditioner controls the set temperature automatically, and you cannot change the set temperature. |
| Warm air does not come out of the air conditioner. | Check whether the outdoor unit is designed for cooling only. In this case, warm air does not come out although you select the Heat mode.Check whether the remote control is designed only for cooling only. Use a remote control that supports both cooling and heating. |
| The fan speed does not change. | Check whether the Auto or Dry mode is running. In these modes, the air conditioner controls the fan speed automatically, and you cannot change the fan speed. |
| The wireless remote control does not operate. | Check whether the batteries are discharged. Replace the batteries with new ones.Make sure that nothing is blocking the remote control sensor.Check whether any strong lighting sources are near the air conditioner. Strong light which comes from fluorescent bulbs or neon signs may interfere with the remote control. |
| Problem Solution | |
| The wired remote control does not operate. | ·Check whether the indicator is displayed at the bottom right of the remote control display. In this case, turn off both the air conditioner and the auxiliary power switch, and then contact a service centre. |
| The air conditioner is not turned on or off immediately with the wired remote control. | ·Check whether the wired remote control is set for group control. In this case, the air conditioners connected to the wired remote control are turned on or off sequentially. This operation takes up to 32 seconds. |
| The Timed on/off function does not operate. | ·Check whether you pressed the (SET) button on the remote control after setting the on/off time. Set the on/off time. |
| The indoor unit display blinks continuously. | ·Turn on the air conditioner again by pressing the (Power) button.·Turn off and then turn on the auxiliary power switch, and then turn on the conditioner.·If the indoor unit display is still blinking, contact a service centre. |
| I want to get cooler air. | ·Operate the air conditioner with a common fan to save energy and enhance the cooling efficiency. |
| The air is not cool or warm enough. | ·In the Cool mode, cool air does not come out if the set temperature is higher than the current temperature.- MR-EH00U remote control: Press the Temperature button repeatedly until the set temperature (minimum : 18°C (64°F)) is set to lower than the current temperature.- AR-KH00U remote control: Press the Temperature button on the remote control. Then rotate the Wheel until the set temperature (minimum : 18°C (64°F)) is set to lower than the current temperature.·In the Heat mode, warm air does not come out if the set temperature is lower than the current temperature.- MR-EH00U remote control: Press the Temperature button repeatedly until the set temperature (maximum : 30°C (86°F)) is set to higher than the current temperature.- AR-KH00U remote control: Press the Temperature button on the remote control. Then rotate the Wheel until the set temperature (maximum: 30°C (86°F)) is set to higher than the current temperature. |
| Problem Solution | |
| The air is not cool or warm enough. | Both cooling and heating do not operate in the Fan mode. Select the Cool, Heat, Auto, or Dry mode.Check whether the air filter is blocked with dirt. A dusty filter may decrease the cooling and heating efficiencies. Clean the air filter frequently.If a cover is on the outdoor unit or any obstacle is present near the outdoor unit, remove them.Install the outdoor unit in a well-ventilated place. Avoiding places exposed to direct sunlight or close to a heating appliance.Place a sunscreen over the outdoor unit to protect it from direct sunlight.If the indoor unit is installed in a place exposed to direct sunlight, pull the curtains on the windows.Close the windows and doors to maximize the cooling and heating efficiencies.If the Cool mode is stopped and then started immediately, cool air comes out after about 3 minutes to protect the compressor of the outdoor unit.When the Heat mode is started, warm air does not come out immediately to prevent cool air from coming out at the beginning.If the refrigerant pipe is too long, the cooling and heating efficiencies may be decreased. Avoid exceeding the maximum pipe length. |
| The air conditioner makes strange noises. | In certain conditions (especially, when the outdoor temperature is lower than 20°C (68°F)), a hissing, rumbling, or splashing sound may be heard while the refrigerant is circulating through the air conditioner. This is a normal operation.When you press the (Power) button on the remote control, noise may be heard from the drain pump inside the air conditioner. This noise is a normal sound. |
| Unpleasant odours permeate the room. | If the air conditioner is running in a smoky area or if there is a smell entering from outside, ventilate the room properly.If both indoor temperature and indoor humidity are high, operate the air conditioner in the Clean or Fan mode for 1 to 2 hours.If the air conditioner has not been operated for an extended period of time, clean the indoor unit and then operate the air conditioner in the Fan mode for 3 to 4 hours to dry the inside of the indoor unit for removal of unpleasant odours.If the air filter blocked with dirt, clean the air filter. |
Cleaning and Maintaining
| Problem Solution | |
| Steam is produced on the indoor unit. | · In winter, if the indoor humidity is high, steam may be produced around the air outlet while the defrost function is running. This is a normal operation. |
| The outdoor unit fan continues to operate when the air conditioner is turned off. | · When the air conditioner is turned off, the outdoor unit fan may continue to operate to reduce noise of the refrigerant gas. This is a normal operation. |
| Water drops from the piping connections of the outdoor unit. | · Condensation may develop due to the difference in temperature. This is a normal condition. |
| Steam is produced on the outdoor unit. | · In winter, when the air conditioner runs in the Heat mode, the frost on the heat exchanger melts and steam may be produced. This is a normal operation, neither product malfunction nor a fire. |
