Fridge Freezer Noisy: Causes and Solutions

Fridge Freezer Noisy

A noisy fridge freezer can be quite a nuisance in your kitchen. The constant hum, buzz, or even rattling can be both distracting and worrying. But don’t fret! In many cases, the noise is due to some minor issues that you can fix yourself. In this blog post, we’ll explore the common causes of a noisy fridge freezer and provide you with practical solutions to restore peace and quiet in your kitchen.

Ice Build Up

A noisy fridge freezer could be due to several reasons. One of them could be due to ice build-up on the fan in the freezer. This could happen if the defrost system of your freezer is not working properly, causing frost to accumulate on the evaporator coils and the fan.

When the fan hits this ice, it can cause a lot of noise. To fix this issue, you would need to defrost your freezer. Here’s a step-by-step guide on how to do it:

1. Unplug the Fridge Freezer: Always start any repair by disconnecting the appliance from the power source.
2. Empty the Freezer: Remove all food items from your freezer and store them in a cool place.
3. Locate the Fan: The fan is usually located at the back of the freezer compartment. You might need to remove a panel to get to it.
4. Check for Ice Build-up: If there’s ice on the fan, that’s likely causing the noise.
5. Defrost the Freezer: The easiest way to get rid of the ice is to defrost the freezer. You can do this by turning off the fridge freezer and leaving the freezer door open. Place towels around the base of the freezer to soak up any water that comes out during the defrosting process. This could take several hours, so be patient.
6. Check the Defrost System: Once the ice is gone, it’s a good idea to check the defrost system to make sure it’s working properly. If it’s faulty, the ice will just build up again. The defrost system consists of a defrost heater, a defrost thermostat, and a defrost timer or control board. If you’re not comfortable checking these components yourself, you might want to call a professional.
7. Clean and Dry the Freezer: After all the ice is melted, clean the inside of the freezer with a mixture of warm water and baking soda ora mild detergent. This will clean as well as help to eliminate odours. Dry the freezer thoroughly.
8. Turn the Fridge Freezer Back On: Once the freezer is clean and dry, you can plug it back in. It will take a while for it to get back to its normal operating temperature.
9. Monitor the Noise: After the freezer has been defrosted and turned back on, listen to see if the noise has stopped. If it has, then the problem was likely due to ice build-up on the fan. If the noise continues, there might be another issue, and you should consider calling a professional.

Other Causes Of A Noisy Fridge Freezer

1. Loose Drain Pan

The drain pan is located at the bottom of your fridge freezer. If it’s loose, it can cause a rattling noise. To fix this, you simply need to secure the pan back in place with the existing hardware.

2. Faulty Defrost Timer

A ticking or scraping sound could indicate a faulty defrost timer. If you notice frost buildup in the refrigerator and freezer compartments (assuming the thermostat is set correctly), this could be a sign of a failing timer. The noise might only occur once or twice per day, for about an hour, which is another sign that the defrost timer should be replaced.

3. Dirty or Damaged Condenser Fan

The condenser fan is located behind an access panel on the back of the fridge. It circulates air through the condenser coil to remove heat and also over the drain pan to evaporate the defrost water. If the fan is dirty or damaged, it can cause a loud noise. To fix this, unplug the fridge, inspect the fan for any wear and tear, and clean any dirt or debris that could be obstructing the fan.

4. Faulty Evaporator Fan Motor

The evaporator fan motor is located at the back of the freezer section inside the refrigerator. It circulates air through the freezer and fridge. If the fan is faulty, the noise will get louder when you push in the light switch in the freezer. To fix this, unplug the fridge, spin the fan blade with your hand to see if it’s operating smoothly, and check wires, grommets, and other components for signs of wear and tear. If the fan blade doesn’t move freely or there are other signs of damage or corrosion, it may be necessary to replace the fan and surrounding parts.

5. Refrigerator Compressor Noise

The compressor is located at the bottom rear of the fridge. If it’s making a loud noise, it could be due to a problem with the compressor. To check this, unplug the motor of the condenser fan, plug your refrigerator back in, and see if the noise continues. If it does, the compressor may be the problem.

Remember, while some of these fixes can be done at home, others might require professional assistance. If you’re unsure, it’s always best to call a professional to avoid causing further damage to your fridge freezer.
