Troubleshooting
• As the refrigerator cools or freezes, refrigerant gas moves through sealed pipes, causing
bubbling sounds.
• As the refrigerator temperature increases or decreases, plastic parts contract and
expand, creating knocking noises. These noises occur during the defrosting cycle or
when electronic parts are working.
• For ice maker models: When the water valve opens to fill the ice maker, buzzing sounds
may occur.
• Due to pressure equalizing when opening and closing the refrigerator door, whooshing
sounds may occur.
