Over time mineral deposits can accumulate inside the valve and restrict the water flow. The water inlet valve is an electrically controlled valve that opens to supply water to the refrigerator dispenser and icemaker. Unless the fan assembly breaks this is simply a mechanical phenomenon that you can live with. Water lines supplying the refrigerator may make a loud bang due to a condition called water hammer.

You may need to open the freezer door to clearly hear if the noise is inside or outside. You can usually trace the sound to its source and decide whether to fix it yourself or call an appliance pro. Skip to step 3 if the sound is on the outside or coming from behind the freezer. During normal operation a refrigerator makes a number of noises but most of them are unnoticeable.

Water hammer is a knocking or banging noise in a water line that occurs when the water valve opens and closes. While the most likely reason for a refrigerator to make a knocking sound is the compressor the condenser fan might also cause a fridge banging noise. Listen carefully to determine whether the knocking noise is coming from the inside or outside of the freezer. This may occur if the fan becomes clogged with lint or other debris which reduces air flow and makes a clicking knocking or whistling sound.
