Operating Instructions
Normal Operating Sounds
Certain sounds may be made when air conditioner runs,
especialJy in a cooling mode. Sounds may include:
• Water splashing onto condenser; caused by slinger
ring attached to condenser fan. Slinger ring picks up
water (condensate) in base pan and sprays it on
condenser to increase efficiency of unit.
• Compressorcycles frequently. High efficiency
compressors used in new Kenmora Room
AirConditionersrun more frequently but for shorter
periods and consume less energy than older, less
efficientcompressors.
• Airflowfrom air discharge vent. If sound is distracting,
try adjusting louvers on discharge vent, moving objects
that may be obstructing airflow, or reducing fan speed.
