To Next PageTo Next PageWhy Samsung Air Conditioner compressor does not operate in COOL mode?
In COOL mode, if the room temperature is higher than the set temperature, the compressor might not operate. This happens after a delay of 3 minutes when the compressor is re-operated.
What to do if the Timer LED is on and the Samsung AQV09NSD Air Conditioner won't start?
The Timer LED indicates that the timer is activated and the unit is in ready mode. To resolve this, cancel the timer operation. After canceling, the unit should operate normally.
Why does my Samsung Air Conditioner compressor stop and fan speed decrease?
The compressor may stop intermittently, or the fan speed of the indoor unit may decrease, to prevent inside/outside air from freezing. This depends on the inside/outside air temperature.
Why does the compressor and fan stop in HEAT mode on my Samsung AQV09NSD Air Conditioner?
In HEAT mode, the compressor and indoor fan may stop intermittently if the room temperature exceeds the set temperature. This is to protect the compressor from overheated air.
Why is the compressor running when my Samsung Air Conditioner is off in HEAT mode?
If the unit is turned off while de-icing is active, the compressor will continue to operate for up to 9 minutes (maximum) until the de-icing process is completed.
How to adjust the fan speed in DRY mode on my Samsung Air Conditioner?
Fan speed cannot be adjusted in DRY mode. The speed of the indoor fan is automatically set to LL (Low Low) in DRY mode.
