Refrigerator Making a Loud Noise

Quick answer

A loud refrigerator noise can often be resolved by checking the condenser coils, leveling the unit, and ensuring the compressor is functioning properly. Turn off the power before inspecting components.

Confirm the symptom

• Loud humming, buzzing, or clicking noise from the refrigerator
• Noise is constant or occurs during specific cycles
• Noise is louder than usual or recently started

Tools and prep

• Screwdrivers (flathead and Phillips)
• Flashlight
• Level
• Vacuum cleaner with brush attachment
• Work gloves
• Turn off the refrigerator and unplug it before starting

Step-by-step troubleshooting

1. Check Condenser Coils
   Do: Locate the condenser coils (usually underneath or at the back of the fridge) and use a flashlight to inspect them for dust or debris.
   Observe: Dusty or clogged coils can restrict airflow and cause noise.
   Means: Dirty coils are a common cause of loud noises.
   Next: Clean the coils with a vacuum cleaner.
2. Clean Condenser Coils
   Do: Use the vacuum cleaner with a brush attachment to gently remove dust and debris from the coils.
   Observe: Coils should be free of dirt and debris after cleaning.
   Means: Clean coils improve airflow and reduce noise.
   Next: Reassemble any panels and plug in the refrigerator.
3. Level the Refrigerator
   Do: Use a level to check if the refrigerator is sitting evenly on the floor. Adjust the leveling feet as needed.
   Observe: An uneven refrigerator can vibrate and create noise.
   Means: Improper leveling is a common cause of noise.
   Next: Plug in the refrigerator and monitor for noise.
4. Inspect the Compressor
   Do: Listen for loud humming or buzzing coming from the compressor (usually at the back or bottom of the fridge).
   Observe: A loud or unusual compressor noise may indicate a problem.
   Means: Compressor issues can cause loud noises and require professional attention.
   Next: If the noise persists, contact a professional technician.
5. Check the Fan Motor
   Do: Locate the condenser fan motor (usually near the condenser coils) and listen for unusual noises when the refrigerator is running.
   Observe: A noisy or malfunctioning fan motor can cause loud noises.
   Means: Fan motor issues may require replacement.
   Next: If the fan motor is faulty, contact a professional technician.
6. Inspect the Evaporator Fan
   Do: Open the freezer compartment and listen for loud noises coming from the evaporator fan.
   Observe: A noisy evaporator fan may indicate a problem.
   Means: Evaporator fan issues may require replacement.
   Next: If the fan is faulty, contact a professional technician.
