The cracking noise you hear is likely due to temperature changes affecting the parts inside your Panasonic Air Conditioner.
Why is my Panasonic U-18ME1E81 Air Conditioner cooling or heating poorly?
If your Panasonic Air Conditioner's cooling or heating performance is poor, check if the air inlet or outlet of the indoor and outdoor units are blocked by dust and remove any dust. Also, ensure the air speed control is set to 'High' or 'Strong'. Verify that the temperature settings are correct by lowering the temperature setting or setting it to 'High' or 'Strong'. Finally, consider that direct sunlight exposure in cooling mode can affect performance.
Why does my Panasonic Air Conditioner not start immediately?
Operation is not activated for the first approx. 3 minutes because compressor protection circuit is activated.
Why does my Panasonic Air Conditioner sound like water is running?
The sound of streaming water you hear is likely the sound of refrigerant liquid flowing inside the unit during or after operation or the sound of drainage water through the drain pipe.
Why does my Panasonic Air Conditioner smell?
Your Panasonic Air Conditioner might smell because indoor odor components like cigarette or cosmetic odors have accumulated and are being discharged. It could also be due to a dusty unit inside. In both cases, it is recommended to consult your dealer.
What causes dewdrop formation on my Panasonic U-18ME1E81 Air Conditioner?

Why is the wind direction changing on my Panasonic Air Conditioner and I can't adjust it?
Your Panasonic Air Conditioner may automatically adjust to a horizontal wind flow when the air discharge temperature is low, or during defrost operation. Also, the flap position is occasionally set up individually.
