• 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

when electronic parts are working.
• Due to pressure equalizing when opening and closing the refrigerator door,
whooshing sounds may occur.
