• You may hear a pinging noise caused by water being picked up and thrown by the slinger fan against the
condenser on rainy days or when the humidity is high. This design feature helps remove moisture and
improve efficiency.
• You may hear the thermostat click when the compressor cycles on and off.
• Water will collect in the base pan during high humidity or on rainy days. The water may overflow and drip
from the outdoor side of the unit.
• The fan may run even when the compressor does not.
