The normal operation of your refrigerator will cause some sound. The following list contains sounds that are normal.
• A change in fan speed as the refrigerator responds to changes in temperature due to door opening.
• A clicking/tic toc noise can be heard when the defrost timer switches on and off.
• A click can be heard when the temperature control unit turns the unit on and off.
• A boiling, gurgling, or knocking sound can be heard when the unit is running. This is caused by the circulation of refrigerant.
• Gurgling sound in the door. This sound can be heard just after the door is closed because of the water in drain tube trap area. It can last several seconds.
• A drip may be heard when defrost water is dripping into the pan beneath the refrigerator.
• A hum or click can be heard when the icemaker fills with water. This sound may be heard once or multiple times.
• The icemaker will make a loud noise when cubes are dropped into the bucket.
• Buzzing noises can be heard after getting water from the door dispenser. The noise should not last longer than 7 seconds.
• A snapping sound will be heard about 4 seconds after removing a glass from a dispenser. This is the sound of the dispenser chute closing.
• A clicking noise may be heard after a power shortage. This stems from the compressor trying to re-start itself. The noise could last for 3 to 5 minutes.
• A hissing, sizzling, buzzing, or arching noise may be heard on self-defrost models. This is produced when water drips on defrost heaters.
