Brief Overview of Fridge Compressor Noise
Fridge compressor noise is a type of sound that originates from the heart of your fridge – the compressor. It’s the device that does the heavy lifting to keep your food cold, but when it gets noisy, it can cause some serious headaches.
Quick Answer to ‘Why is my refrigerator compressor noise loud?’
Fridge compressor noise can get loud due to a variety of reasons. It could be due to technical issues like motor failure or loose parts, or environmental factors such as poor ventilation or unstable flooring.
Understanding the Role of a Refrigerator Compressor
To tackle the noise, it helps to know what a refrigerator compressor does, and what it should normally sound like.
The Function of a Refrigerator Compressor
The compressor is the powerhouse of your fridge. It compresses the refrigerant gas, raising its temperature and pressure, before circulating it through the coils, where it cools down and absorbs the heat from inside the fridge. This keeps your food fresh and cool. Quite important, isn’t it?
Normal Sound vs Noise: What should your Refrigerator Compressor Sound Like?
A normal refrigerator compressor produces a low hum or purr. It’s the sound of it working hard to keep your food cold. However, if the sound intensifies or changes into a buzzing, clicking, or knocking noise, you might have a problem. And trust us, ignoring it is not a good idea.
Identifying Different Types of Fridge Compressor Noises
So, your fridge is making weird sounds. But what does each sound mean? Let’s find out.
Common Noises from the Refrigerator Compressor and What They Indicate
