From common culprits like coil issues to fan problems, we’ll break down the possibilities and provide step-by-step instructions to silence the roar and restore tranquility to your kitchen.

Why is My Fridge Making Noise? Common Sources
Refrigerators are complex appliances with various components that can generate noise. Identifying the source of the fridge making a loud noise is the first step in addressing the issue. Here are the most common culprits:
- Compressor: Often located at the back of the fridge, the compressor can produce a humming or buzzing sound. This noise is usually normal but can become excessive if there is an issue.
- Evaporator Fan: Situated inside the freezer compartment, this fan circulates air throughout the fridge. A faulty evaporator fan can make a rattling or squealing noise.
- Condenser Fan: Located near the compressor, this fan cools down the condenser coils. If obstructed or malfunctioning, it can create a loud noise.
- Defrost Timer: Responsible for the defrost cycle, the defrost timer can produce a clicking sound. While some noise is normal, excessive clicking can indicate a problem.
- Water Inlet Valve: If your refrigerator has an ice maker or water dispenser, the water inlet valve may produce a buzzing or vibrating sound when filling.
