Why is no cool or warm air coming out of my Samsung AJ040 Air Conditioner?
- L
  Lynn BarberAug 16, 2025
  If cool or warm air isn't coming out of your Samsung Air Conditioner, several factors could be at play. First, ensure that the set temperature isn't higher (in Cool mode) or lower (in Heat mode) than the current room temperature. Adjust it using the Temp + or - buttons on the remote. Also, a dirty air filter can decrease performance, so clean it frequently. Check that the outdoor unit isn't covered or obstructed. If operating in sunlight, consider shading the outdoor unit. The unit might be in De-ice mode, during which the indoor fan stops. Ensure doors and windows are closed to maintain cooling/heating efficiency. If the unit was just turned on after being off, only the fan might run initially to protect the compressor. Finally, excessive pipe length can also reduce performance.

  If your Samsung Air Conditioner remote controller isn't working, start by checking the batteries to ensure they aren't depleted. Also, make sure that nothing is blocking the remote controller sensor. Strong light from fluorescent bulbs or neon signs nearby may also interfere with the electric waves.
