Is your Whirlpool refrigerator making noise that disrupts the peace and quiet of your kitchen? While some operational sounds are normal, a sudden increase in volume or strange new sounds like clicking, humming, or grinding often indicates a specific component failure.
Use this professional troubleshooting guide to identify the source of the noise and determine the necessary replacement parts.
Whirlpool Refrigerator Making Noise: Common Causes and Solutions
To effectively fix a Whirlpool refrigerator making noise, you must first identify the type of sound and its location. The most common culprits include the compressor, fan motors, and the ice maker assembly.

1. Loud Humming or Buzzing Noise
A low hum is normal for a running refrigerator, but if the sound becomes aggressive or loud, it points to electrical or motor issues.
- Compressor: This is the heart of the cooling system. A soft hum is standard, but a loud, aggressive buzz that cuts in and out suggests the compressor is struggling. If you hear a “click-buzz-click” pattern, the start relay may be failing to engage the compressor.
- Ice Maker & Water Inlet Valve: A loud buzzing sound that occurs for a few seconds is often the water inlet valve trying to open. If the water supply is turned off or the line is kinked, the valve will buzz loudly as it attempts to draw water.
- Troubleshooting: Check if the water supply line is connected and turned on. If the noise persists despite good water flow, the valve solenoid may be defective and require a replacement part.
2. Clicking Sound
A repetitive or intermittent clicking sound is a distinct symptom that usually points to one of three specific components.
- Defrost Timer: On older Whirlpool models, the mechanical defrost timer makes a distinct click when switching the fridge between cooling and defrost cycles. If the timer gets stuck, it may produce a continuous ticking noise.
- Start Relay: As mentioned above, if the clicking comes from the bottom rear of the unit and accompanies a warm fridge, the compressor’s start relay (PTC relay) is likely damaged.
- Water Valve: The water inlet valve can also click if it is receiving a signal but failing to open fully.
3. Squealing or Chirping Noises
High-pitched squealing usually indicates a failing motor bearing or friction in one of the fans.
- Evaporator Fan Motor: Located in the freezer compartment, this fan circulates cold air. If the noise gets louder when you open the freezer door, the evaporator fan motor is likely the cause. Over time, the bearings dry out, or ice buildup may cause the fan blade to hit the housing.
- Action Step: Remove the rear freezer panel to inspect for ice obstruction. If the fan blade spins freely by hand but is noisy under power, replace the motor.
- Condenser Fan Motor: Located at the bottom rear near the compressor, this fan cools the condenser coils. If it is obstructed by dust, lint, or debris, it can make a squealing or rattling noise.
- Action Step: Pull the refrigerator out and clean the rear access panel. Spin the fan blade manually; if it is stiff or wobbles, the motor needs replacement.
4. Vibration and Rattling
Rattling sounds are often the easiest to fix as they are frequently caused by physical positioning rather than component failure.

- Leveling: If the refrigerator is not level, the compressor’s natural vibration can cause the entire unit to rattle against the floor or cabinets. Ensure the leveling legs are adjusted so the fridge sits firmly.
- Drain Pan: The drain pan underneath the fridge can sometimes vibrate loose. check to ensure it is secured properly.
- Condenser Fan Blade: A damaged or unbalanced fan blade on the condenser motor can cause excessive vibration. Inspect the blade for cracks or missing fins.
5. Grinding Noise
A grinding noise is almost exclusively related to the ice maker or the motors involved in dispensing ice.
- Ice Maker Assembly: If you hear grinding from the freezer, ice may be jammed in the ejector arms, or the internal gears of the ice maker module are stripped.
- Auger Motor: If the noise occurs only when you press the dispenser lever for ice, the auger motor (which pushes ice to the door) is likely failing or obstructed by a block of frozen ice.
Summary of Replacement Parts
When troubleshooting a Whirlpool refrigerator making noise, you may need to order specific replacement parts. Always verify your model number before purchasing.

| Noise Symptom | Likely Culprit | Replacement Part Needed |
|---|---|---|
| Loud Humming | Water Valve or Compressor | Water Inlet Valve, Start Relay |
| Clicking | Start Relay or Defrost Timer | Compressor Start Relay, Defrost Timer |

Conclusion
Ignoring a Whirlpool refrigerator making noise can lead to more serious cooling failures and food spoilage. Most noises, such as those from a condenser fan motor or a fan blade hitting ice, are relatively simple DIY fixes. However, if the noise comes directly from the internal components of the compressor (loud knocking), it often signals a sealed system failure that requires a professional technician. By systematically checking these entities, you can restore quiet operation to your kitchen.
Frequently Asked Questions
Why does my refrigerator make a squealing noise that gets louder when I open the freezer door?
This sound is typically caused by the evaporator fan motor located inside the freezer. If the noise increases when the door is open, it indicates that the fan motor bearings are failing or the fan blade is hitting ice buildup. You should inspect the fan for obstructions or replace the motor if the noise persists.
What does it mean if my fridge is clicking and not cooling properly?
A repetitive clicking sound coming from the bottom rear of the unit usually points to a faulty compressor start relay. This component is responsible for “starting” the compressor; if it fails, the compressor will attempt to turn on, click, and then shut off, resulting in a warm refrigerator.
Is a buzzing noise from the ice maker normal?
A short buzzing sound lasting a few seconds is normal—it is the sound of the water inlet valve opening to fill the ice maker. However, if the buzzing is loud and continuous, it may indicate that the water supply is turned off, the line is kinked, or the valve solenoid is defective.
How can I stop my Whirlpool refrigerator from rattling or vibrating?
Most rattling sounds are caused by the refrigerator being unlevel. Check the leveling legs to ensure the unit is sitting firmly on the floor. Additionally, ensure the drain pan underneath the fridge is secure and that the condenser fan blade at the rear is not hit by debris or lint.

When should I stop troubleshooting and call a professional?
While most fan and valve issues are DIY-friendly, a loud knocking or thumping sound coming from inside the compressor itself usually indicates a mechanical failure within the sealed system. Because these repairs involve refrigerant and specialized tools, they require a professional technician.
