  Your Alen Air Conditioner might not be cooling effectively due to several reasons. Ensure all windows and doors are closed to prevent warm air from entering. Remove any heat sources from the room. Check that the exhaust air duct is properly connected and not blocked. The temperature setting may be too high, so try decreasing it. Lastly, a dusty air filter can restrict airflow, so clean the air filter.

  If your Alen Air Conditioner fails to start when you press the 1/0 button, it could be due to a few reasons. If the water full indicator is blinking, empty the water tank. Alternatively, if you are in heating mode, the room temperature might be higher than the set temperature, so reset the temperature. If in cooling mode, the room temperature might be lower than the set temperature; in that case, reset the temperature as well.
