New Refrigerator Noises to Expect
Here are some normal new refrigerator noises.
During Normal Operation
Rattling or vibrating can be refrigerant flowing through the cooling system or water flowing through the water line.
A pulsating or high-pitched sound can come from the compressor or fans as they adjust to optimize performance. They’re different from the steady speed motors and fans you are used to on your old model.
Gurgling as the refrigerator shuts off after a cooling cycle is the refrigerant flowing through the tubing in the cooling system. You might also hear gurgling when you open or close the refrigerator or freezer door as water equalizes in the drain pan when air is forced through the tube.
During the Defrost Cycle
Dripping during the defrost cycle is water running into the drain pan in the back of the freezer compartment.
Sizzling or hissing during the defrost cycle is water dripping on the defrost heater as it runs into the drain pan.
Popping or cracking can be the contraction and expansion of the inside walls of the refrigerator when the refrigerator cools for the first time or defrosts.
If You Have an Ice Maker
Buzzing is the water valve opening to fill the ice maker.
Thumping or hammering can be the ice maker’s water supply line banging against the wall or back of the refrigerator during the fill cycle. If this sound seems excessive, check the supply line behind the refrigerator.
Cracking can be ice cubes being ejected from the ice maker, followed by a crashing sound as they fall into the ice bin.
Keep in mind that hard surfaces, such as the floor, walls and cabinets, can amplify these sounds. Try adjusting the refrigerator’s position or putting a mat on the floor to reduce the noise level.
