Phenomenon
Analysis and Solution
Indoor unit fan
stops for about
10 minutes while
outdoor unit is
still in operation
at heating mode.
You may hear the
craking sounds.
You may hear the
sound like running
water.
You may hear"POOSH"
sound and "CLICK"
sound.
You may smell some
odor blowing out of
the air that
air-conditioner.
Condensate found
in outdoor unit
drain pan.
It may be defrosting the outdoor unit coil.
This process should complete in about
10 minutes at most (it freezes when
outdoor temperature is low and humidity
is high).
Friction sounds could be caused by expansion
and contraction of front panel due to temperature
changes at unit startup or shutdown.
During cooling, condensate from pipes or coils
accumulated.
During heating, condensate at heat-exchanger
coil drips.
During heating, at defrosting, melt ice builds up
condensate.
Odors from the filter or coil (dust, moisture,
fungi, mold
). Need to clean filter.
Heater is clicked on. Don't need to be worried
about.
If abnormal, need to check the unit.
POOSH
sound of refrigerant flow change
when cooling or heating mode is finished.
Click
sound of fan or compressor when
contactors being engaged.
Sound of running refrigerant in air-conditioner
due to its expansion or flowing.
Sound of accumulated condensate dripping
from the heat-exchanger to dain pan.
Melting sounds of frost on heat-exchanger.
