Normal operatlng sounds . . .
When your room air conditioner is operetlng
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.
