Noise often occurs in heating mode during defrost operation.
Why won't my Panasonic Air Conditioner turn on immediately?
When power is turned ON instantly, operation is not activated for the first approximately 3 minutes because the compressor protection circuit is activated.
Why does my Panasonic Air Conditioner smell?
The discharged air from your Panasonic Air Conditioner might smell due to indoor odor components, such as cigarette or cosmetic odors, that have accumulated inside the unit. Alternatively, the unit inside may be dirty, in which case you should contact your dealer.
How to fix a noisy Panasonic U-20ME1H8 Air Conditioner?
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 does the fan keep running on my Panasonic U-20ME1H8 after I turn it off?
The fan in your Panasonic Air Conditioner may continue to run even after you turn it off to ensure smooth operation. Also, depending on the settings, the fan may rotate to dry the heat exchanger.
Why is my Panasonic Air Conditioner discharging dust?
If your Panasonic Air Conditioner is discharging dust, it is likely due to accumulated dust inside the indoor unit being expelled.
Why does my Panasonic U-20ME1H8 Air Conditioner's fan run faster than the set speed at the start?
At the initial high-speed operation, the fan may sometimes rotate faster (for 3 to 30 minutes) than the setting speed in order to confirm whether the fan motor rotation is within use range.
Why does the outdoor fan on my Panasonic U-20ME1H8 keep running after I turn it off?
The outdoor unit fan may continue to operate for a while after the Panasonic Air Conditioner is turned off via remote to ensure smooth operation.
Why won't the wind direction change on my Panasonic U-20ME1H8 Air Conditioner?
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?
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.
