Items to be checked first
1. Is the voltage of the power correct? The input voltage shall be rating voltage 10%. The air conditioner may not operate properly if the voltage is out of this range.
2. Is the link cable connecting the indoor unit and the outdoor unit linked properly? Please refer to the “wiring diagram” Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables.
3. When a problem occurs due to the contents illustrated in the table below, it is symptom not related to themalfunction of the air conditioner.


Operation of air conditioner = In COOL operation mode, the compressor does not operate at a room temperature higher than the setting temperature that the indoor fan should operate.In a HEAT operation mode, the compressor does not operate at a room temperature lower than the setting temperature that indoor fan should operate.

Explanation = It happens after a delay of 3 minutes when the compressor is reoperated. The same phenomenon occurs when a power is on.As a phenomenon that the compressor is reoperated after adelay of 3 minutes, the indoor fan is adjusted automatically withreference to a temperature of the air blow.


Operation of air conditioner = Fan speed setting is not allowed in AUTO or DRY mode

Explanation = The speed of the indoor fan is set to low in DRY mode.Fan speed of 3 steps is selected automatically in AUTO mode.


Operation of air conditioner = Compressor stops operation intermittently in DRY mode.

Explanation = Compressor operation is automatically controlled in DRY modedepending on the room temperature and humidity.


Operation of air conditioner = Compressor of the outdoor unit is operating although it is turned off in HEAT mode.

Explanation = When the unit is turned off while de-ice is activated, thecompressor continues operation for up to 10 minutes(maximum)until the deice is completed.


Operation of air conditioner = Timer indicator lamp lights up and the air conditioner doesnot operate.

Explanation = Timer is being activated and the unit is in ready mode.The unit operates normally if the timer operation is cancelled


Operation of air conditioner = The compressor and indoor fan stop intermittently in HEATmode.

Explanation = The compressor and indoor fan stop intermittently if room temperature exceeds a setting temperature in order to protectthe compressor from overheated air in HEAT mode


Operation of air conditioner = Indoor fan and outdoor fan stop intermittently in HEAT mode.

Explanation = The compressor operates in a reverse cycle to remove exteriorice in HEAT mode, and indoor fan and outdoor fan do not operate intermittently for within 20% of the total heat operation


Operation of air conditioner = The compressor stops intermittently in COOL mode or DRYmode, and fan speed of the indoor unit decreases

Explanation = The compressor stops intermittently or the fan speed of the indoor unit decreases to prevent inside/outside air frozendepending on the inside/outside air temperature.

error code A5 in york Air condition what mean?

Air Conditioning providing accurate temperature control,
and it reduce the humidity within your home to eliminate the 'stickiness' .
Most systems have a dedicated 'dry' mode,
where humidity can be reduced without over-cooling the room.
