Normal operating
sounds
. . .
When your room air conditioner is operating
normally,
you will hear sounds such as:
l
Droplets of water hitting the condenser, causing
a "pinging" or "clicking" sound. Water droplets
help to cool the condenser.
l
Air movement from the fan, especially on high
fan speed settings.
l
Clicks from the cooling cycle.
Sounds also may be caused by house construc-
tion - such as vibration of the unit due to wall
construction
or unsteady window mounting area.
