    Why is my Panasonic U-20ME1H8 Air Conditioner emitting fog?
    • M
      Malik AverySep 23, 2025
      Fog occurring during cooling mode in your Panasonic Air Conditioner, especially in places with oil mist (like restaurants), indicates that the unit inside (heat exchanger) is dirty and needs cleaning. Also fog can appear during defrost operation.

      The noise you hear from your Panasonic Air Conditioner could be due to a few reasons: it could be the sound of refrigerant liquid flowing inside the unit, the sound of drainage water through the drain pipe, or sound due to temperature changes of parts. These are normal and do not indicate a problem.

    Why won't the wind direction change on my Panasonic U-20ME1H8 Air Conditioner?
    • P
      Peter Allen DVMSep 6, 2025
      The wind direction on your Panasonic Air Conditioner might change automatically or be unchangeable because when the air discharge temperature is low, or during defrost operation, horizontal wind flow is made automatically. Also, the flap position may occasionally be set up individually.

    Why is my Panasonic U-20ME1H8 making noise?
    • W
      William JonesSep 3, 2025
      Your Panasonic Air Conditioner might be making noise due to several reasons: * The sound of refrigerant liquid flowing inside the unit, which sounds like streaming water during or after operation. * The sound of drainage water through the drain pipe, also sounding like streaming water during or after operation. * Cracking sounds due to temperature changes of parts, which you may hear during operation or when the operation stops.
