Why is my Panasonic 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 U-20ME1E81 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 U-20ME1E81 Air Conditioner fan rotate faster than the set speed?
The fan may rotate faster than the set speed during the initial high-speed operation for an operation check to confirm that the fan motor rotation is within the proper range.
What to do if fog occurs during cooling operation of Panasonic U-20ME1E81?
If your air conditioner is installed in a place with a lot of oil mist, like a restaurant, the fog during cooling operation means the unit inside (heat exchanger) is dirty. Contact your dealer.
Why is the wind direction changing on my Panasonic U-20ME1E81 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.
What causes noise in my Panasonic U-20ME1E81 unit?
