Frigidaire Refrigerator Knocking Noise

Water hammer is a knocking or banging noise in a water line that occurs when the water valve opens and closes.

Frigidaire refrigerator knocking noise.

Some refrigerators make knocking noises when cycling on or off as the fan begins to spin or stop. In addition to noise your fridge might not be staying as cool as normal and or may be turning on and off regularly. If the refrigerator is noisy or loud particularly when the ice maker is filling the water inlet valve might be at fault. There could be problems if a sound is too loud goes on too long or repeats too often.

Water lines supplying the refrigerator may make a loud bang due to a condition called water hammer. If you own a frigidaire that is making a knocking sound it could be the result of a couple of different causes. A typical refrigerator can last up to 20 years.

This noise will stop in a few days once the gasket becomes more pliable. The condenser fan motor runs at the same time as the evaporator motor and the compressor. You may need to open the freezer door to clearly hear if the noise is inside or outside. Disconnect your refrigerator from the power source and then remove the rear access panel.

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. The water inlet valve is an electrically controlled valve that opens to supply water to the refrigerator dispenser and icemaker. During normal operation a refrigerator makes a number of noises but most of them are unnoticeable. Also as a general rule an older refrigerator will make more noise than a newer unit.

Skip to step 3 if the sound is on the outside or coming from behind the freezer. Listen carefully to determine whether the knocking noise is coming from the inside or outside of the freezer. Over time mineral deposits can accumulate inside the valve and restrict the water flow. Unless the fan assembly breaks this is simply a mechanical phenomenon that you can live with.
