Our refrigerators operate 24/7, leaving us so in tune with their daily sounds that anything unusual stands out. Why is your Whirlpool refrigerator making noise that sounds like humming? While a quiet hum is normal, a louder volume could indicate compressor problems. Learn how to distinguish normal sounds from potential problems when your Whirlpool refrigerator makes noise.
What it Means When Your Whirlpool Refrigerator Makes Noise
As quiet as modern refrigerators have become, none operate in silence. However, knowing what sounds are normal and what indicates a problem are key to understanding why your Whirlpool refrigerator makes noise.
Humming
Most refrigerators make a quiet humming sound as the compressor runs. This vital component circulates and condenses refrigerant to produce cool air for the refrigerator. While modern compressors may run longer than their older counterparts, their humming should be almost unnoticeable as part of normal operation.
However, if your Whirlpool refrigerator makes noise while humming this is significantly louder in volume, the compressor may be malfunctioning. When this happens, it may continue to operate loudly for a long period of time. However, it should be promptly addressed by a professional to avoid a sudden breakdown that leaves stored items in jeopardy.
Grinding
When your Whirlpool refrigerator makes noise after changing water filter it often sounds like a grinding noise. This can occur when a filter is damaged or incorrectly installed. Refer to your Whirlpool user guide to make sure that the filter is installed correctly. If it is, assess for damage like a broken filter head, missing O-rings, or cracks in the filter housing. A damaged filter can be replaced with a new one, while damage to the filter housing requires professional replacement
If the water filter isn’t at fault, the grinding sound may be due to a water inlet valve malfunction. This valve opens and closes to allow water to flow to the refrigerator from your home supply. When it malfunctions, it may make a grinding sound and prohibit water from flowing. A faulty water inlet valve must be professionally replaced.
Buzzing
What does it mean when my refrigerator is making a buzzing noise? The evaporator fan makes a quiet buzzing sound as it operates, helping to cool and circulate refrigerant. However, louder buzzing sounds could mean that the fan is failing or obstructed, often from icy buildup. This Whirlpool refrigerator noise stops when door open because the evaporator fan motor only runs when the door is closed.
Check the fan blades for obstructions and remove any blockages. If ice has built up around the fan blades, use a hairdryer to carefully melt it away. However, if the blades are broken or don’t turn easily by hand, the fan motor is likely failing and must be professionally replaced.
Rattling or Vibrating
While water or refrigerant can make rattling or vibrating sounds as they circulate, persistent sounds could mean the refrigerator isn’t level. Fortunately, a Whirlpool refrigerator has leveling feet that can be easily adjusted to ensure that it sits evenly. Remove the lower base grille and raise or lower the leveling feet on either side of the refrigerator with a wrench.
If your Whirlpool refrigerator is level and the rattling and vibrating sounds continue, make sure it has adequate space on all sides. If the refrigerator is too tight in its enclosure or rests too closely against a wall its small motions can cause rattling or vibrating sounds. Always make sure there is at least one inch of space on all sides of the refrigerator.
