Why does my refrigerator or freezer rattle or crackle?
A noisy fridge can be unsettling, signaling potential issues. In our comprehensive guide, we’ll explore common culprits behind your refrigerator’s crackling and odd sounds. We’ll examine the crucial components of the refrigeration system and pinpoint the issues that could be causing the racket, helping you restore peace and functionality to your kitchen.
THE POTENTIAL CAUSES FOR THIS FAULT:
WARNING
Before you do anything to your appliance, make sure you disconnect it from the power supply.
There is a risk of electric shock.
Wear suitable protective gloves if you need to dismantle anything.
There is a risk of getting cut or injured.
The starter relay
The starter relay is key to your fridge’s compressor running smoothly. If it’s malfunctioning or showing wear, you might hear popping sounds during startup or shutdown. Additionally, electrical issues or weak connections with the compressor might be the source of these noises.

Capacitor problems
A faulty capacitor can cause popping noises when the compressor is running because the capacitor is responsible for providing the smooth start-up and operation of the compressor.
Faulty klixon or thermostat out of sync
The klixon, also known as the thermostat, is responsible for regulating the temperature inside the refrigerator. If it is faulty, it can cause popping noises when maintaining the desired temperature. Thus, a malfunction of the klixon can also lead to irregular compressor operating cycles, resulting in unusual noises.
Compressor in distress
The compressor is the heart of the refrigeration system. A worn or faulty compressor can generate humming or rattling noises during operation, often indicating the mechanical malfunction or deterioration of internal components. It is important to regularly monitor the condition of the compressor, as a problem in this area can not only cause annoying noises, but also affect the overall operation of the refrigerator, thus compromising its cooling efficiency.
Piping & thermal expansion
The piping of the refrigeration system can also be the cause of popping noises. Temperature variations can cause materials to expand and contract, which can generate cracking noises inside the refrigerator.
