Review the chart below first and you may not need to call for service.

• 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
improves energy efficiency.

• You may hear the thermostat or controls 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.
