Why is no cool or warm air coming out of my Samsung Smart Whisper AR KS Air Conditioner?

If cool or warm air isn't coming from your Samsung Air Conditioner, try these steps: * Adjust the temperature using the Temp + or - buttons on the remote. * Clean the filter, as a dirty filter can reduce cooling or heating performance. * Remove any obstacles blocking airflow after taking the cover off. * Ensure doors and windows are closed. Also, the air conditioner may be in defrost mode during winter or if the outdoor temperature is very low. Sometimes, the unit might only run the fan to protect the outdoor compressor. If the pipe length exceeds the maximum allowable length, cooling or heating performance may decrease.
