What to do if my Klarstein 10035856 is running, but there is no air cooling or pump operation?
- AAmy HerreraAug 5, 2025
If your Klarstein Air Conditioner isn't cooling or pumping air, first ensure that the cooling mode is activated and the corresponding LED indicator is lit. Next, verify that the water tank is adequately filled and that the LED indicator isn't flashing. Also, inspect the pump inlet for any obstructions. If the pump still fails to operate despite these checks, it may be defective, and you should contact customer service.
