Refrigerator Making Loud Noise When Running

Quick answer

A loud refrigerator is often caused by a faulty condenser fan, compressor issues, or loose parts. Turn off the power, check for loose components, and clean the condenser coils to resolve the noise.

Confirm the symptom

• Loud humming, buzzing, or rattling when the refrigerator is running
• Noise persists even when the refrigerator is not cooling
• Noise increases when the refrigerator is under load or during startup

Tools and prep

• Screwdrivers (flathead and Phillips)
• Flashlight
• Soft cloth or brush for cleaning
• Level
• Multimeter (for testing electrical components)
• Work gloves
• Plug in a surge protector for electrical testing
• Turn off the refrigerator and unplug it before starting

Step-by-step troubleshooting

1. Check for Loose Components
   Do: Inspect the refrigerator for any loose parts such as shelves, drawers, or panels.
   Observe: Look for any parts that may be vibrating or rattling.
   Means: Loose parts can cause noise when the refrigerator is running.
   Next: Tighten or secure any loose components and restart the refrigerator to see if the noise stops.
2. Clean Condenser Coils
   Do: Locate and clean the condenser coils, usually found at the back or bottom of the refrigerator.
   Observe: Check for dust, dirt, or debris buildup on the coils.
   Means: Dirty coils can cause the compressor to work harder, leading to noise.
   Next: Use a soft brush or vacuum to clean the coils and restart the refrigerator.
3. Inspect the Compressor
   Do: Listen closely to the compressor area for any unusual noises.
   Observe: Check if the compressor is vibrating excessively or making loud humming sounds.
   Means: A faulty or worn-out compressor can cause loud noises.
   Next: If the compressor is faulty, consider replacing it or contacting a professional technician.
4. Check the Condenser Fan
   Do: Locate the condenser fan and inspect it for damage or obstructions.
   Observe: Look for any debris or objects blocking the fan blades.
   Means: A malfunctioning or obstructed condenser fan can cause loud noises.
   Next: Clean the fan blades and ensure it spins freely. Replace the fan if it's damaged.
5. Test the Evaporator Fan
   Do: Check the evaporator fan for any issues, usually located in the freezer compartment.
   Observe: Listen for any unusual noises or vibrations from the fan.
   Means: A faulty evaporator fan can cause noise and affect cooling performance.
   Next: Clean the fan and ensure it spins freely. Replace if necessary.
6. Check the Level of the Refrigerator
   Do: Use a level to check if the refrigerator is sitting evenly on the floor.
   Observe: Look for any tilting or uneven placement.
   Means: An unlevel refrigerator can cause vibrations and noise.
   Next: Adjust the leveling feet to ensure the refrigerator is level.

Common causes

Parts matching

If you need to replace parts, look for these common components:

• Condenser Fan Motor
• Evaporator Fan Motor
• Compressor
• Refrigerator Leveling Feet
• Replacement Shelves or Panels

Check the model number of your refrigerator to ensure you purchase the correct replacement parts.

When to call a professional

• The noise persists after checking and cleaning all components
• You suspect a faulty compressor and lack the necessary tools or experience
• The refrigerator is not cooling properly despite resolving the noise issue
• You are unsure about handling electrical components or replacing parts
• The refrigerator is under warranty and you don't want to risk voiding it
