Fridge Making Grinding Noise: 6 Easy Ways To Fix It Now

Is your fridge making a grinding noise?

It is normal thing for a fridge to make loud noises due to the presence of the motor, fan, and compressor. 

However, hearing loud noises from a modern fridge is not normal.

These are designed to be as quiet as possible.

So, when your fridge makes a grinding noise, it indicates that one or more components are not working correctly. 

The grinding noise from a refrigerator is a common complaint from different refrigerator owners.

It is not associated with a specific brand or model.

However, it commonly occurs when problems in the fan motor or compressor appear on the surface.

So, constant grinding or rattling sounds require fans and other relevant components to be inspected.

This blog post will help you understand the reasons behind these problems and find the best fixes. So, read on!  

Why is Your Fridge Making A Grinding Noise?

Fridges are expected to make all noise, as they are constantly running. They also have some powerful components that are noisy by default. However, fridges are programmed to emit a continuous soft humming sound to ensure they work simultaneously without annoying you.

Once these almost quiet are replaced by louder noises, you will need to trace the source. But before taking any serious action, it is essential to unplug the fridge and give it time to discharge. We recommend to start looking at the appliance’s fans. 

Now let’s dive deeper into the causes. 

1. Faulty Condenser Fan 

In all types of fridges, a condenser fan is responsible for drawing air from different fridge parts to prevent the compressor and the condenser coils from overheating. Moreover, it keeps the required air circulation going until it reaches the base grill. 

To operate properly, the condenser motor must be in good shape. Otherwise, the fan won’t work, and the relevant components will overheat. Subsequently, the fridge will emit rattling noiseIf neglected, the problem might lead to breaking down the fridge.  

2. Problematic Evaporator Fan  

Another common culprit in strange noises coming from the fridge is the other fan, which is the evaporator fan. This fan is responsible for removing heat from the air circulation. It also enhances cold air circulation and stabilizes the level of cooling inside the fridge. 

Fortunately, any signs of wear or damage will be obvious to see with your eyes. So, you do not have to use any tester or another device to evaluate the performance of this component

3. Malfunctioning Compressor

By default, a fridge usually comes with a noisy compressor. However, a loud refrigerator compressor should not be disturbing to you. Its noise should only be detected if you are close to your fridge.  

A defective compressor will give you an indication that it is failing. You will hear fridge noises resembling intense buzzing or vibrating sounds. The compressor is responsible for pumping and circulating the coolant throughout the fridge. So, it resembles what a heart does to your body. 

A compressor may malfunction when it is not correctly attached to the fridge. Also, a dirty compressor will make the fridge emit abnormal noises. Stuck buildup and debris may lead the compressor to lose its functionality. 

4, Misplaced Drain Pan 

A drain or drip pan in a fridge collects condensed water or defrosted ice that is supposed to leave the fridge. This pan should prevent the fridge water from flooding your kitchen floor. 

While the exact location of this pan can vary depending on the fridge model, it is always found below the appliance’s body. This component might become loose and move away from its correct location. When this happens, you should expect your fridge to make persistent noises. 

5. Problematic Water Line 

Many fridge models come with a built-in water line. This component is a significant plus in modern fridges. It allows you to constantly have fresh cold water without always opening the fridge. Usually, a water line is combined with an ice dispenser to increase indulgence. 

However, these two components may lead to some unusual sizzling sounds. Usually, this sound comes from failed attempts when the ice maker tries to draw in more water

6. An Unlevelled Fridge

A fridge is similar to a washer or a dishwasher in terms of being leveled. They must all be equally balanced to avoid unwanted banging and vibrating noises. To prevent this noise in the first place, your fridge needs to be sitting level. 

How to Fix a Fridge Making a Grinding Noise?

Troubleshooting a noisy fridge might seem frightening to many homeowners. It is valid on some levels. However, there are some fixes you can DIY at home without any difficulties or complications.

Replacing a faulty component or tightening a loose screw won’t require much work or effort. However, if you do not have enough knowledge of similar techniques, you should not hesitate to contact a refrigerator repair technician.

1. Replace the Condenser Motor Fan

If you suspect the condenser motor is failing, you should not run to replace it right away. You should monitor the fan condenser fan blade to ensure they are spinning. They would probably stop spinning when the motor fails.

The first correct action in this case is to test this component. It would be best to use your multimeter to ensure the motor gets the proper voltage. If the motor fails the test, you should get a replacement. The trick lies in getting a matching replacement, as each model has a specific motor. So, avoid buying universal condenser fan motors. 

2. Inspect the Evaporator Fan Motor

An evaporator motor is usually found at the back of the fridge. They are also covered with a panel to protect them from accidental bangs or food debris. However, they are not immune to damage or blockage. So, remove the access panel with screws to reach the fan. Then, inspect the blades to ensure they are not bent or jammed with debris.

If they are dirty, try removing the stuck particles. If damage is present on the surface, you will need a replacement evaporator fan motor. Maybe it is time to replace the entire fan too.

3. Call a Certified Refrigerator Repair Professional

Compressor issues seem to be a bit beyond the abilities of average DIY enthusiasts, especially repair needs. However, removing stuck debris or reattaching the component correctly may sometimes solve the problem. While at it, you should clean the circulation fans and coils. 

4. Adjust the Drip Pan

This is one of the most manageable issues to troubleshoot in a fridge. A misplaced pan can easily get back into shape using firm duct tape. Apply the tape so that the pan is tightly secured in its original place. This should put an end to the rattling water-dripping noises.

5. Call a Plumber 

In most cases, the buzzing sound from a built-in water line results from excessive water pressure. This complex issue is associated with the house’s plumbing system. So, it is better to consult with a plumber to make suitable adjustments to your main water supply feeding the fridge. 

6. Level your Fridge 

This is an effortless troubleshooting step, as it does not require more than using a bubble level. This device can tell whether your fridge is correctly leveled. Make sure to place this device on top of the fridge. If the device shows that the fridge is not level, you can use a wrench to adjust its legs.
