Refrigerator Making Noise and Not Cooling

Quick answer

If your refrigerator is making noise and not cooling, check the condenser coils for dust, ensure the condenser fan is spinning, and verify the evaporator fan is working. If the compressor is running but not cooling, the refrigerant may be low or the coils could be frozen.

Confirm the symptom

• Refrigerator is unusually loud or vibrating
• Interior temperature is not cooling properly
• Compressor is running but not cooling
• Condenser fan or evaporator fan is making noise
• You hear gurgling or clicking sounds

Tools and prep

• Screwdrivers (flathead and Phillips)
• Flashlight
• Thermometer
• Vacuum with brush attachment
• Work gloves
• Turn off fridge and unplug before inspecting internal components
• Ensure the area is dry to prevent electrical hazards

Step-by-step troubleshooting

1. Check Condenser Coils
   Do: Locate the condenser coils (usually underneath or at the back of the fridge) and clean them with a vacuum.
   Observe: Dust or debris on the coils
   Means: Blocked coils reduce cooling efficiency and increase noise.
   Next: Clean coils thoroughly and wait 24 hours to see if cooling improves.
2. Inspect Condenser Fan
   Do: Unplug the fridge and locate the condenser fan (usually near the coils). Check if it spins freely.
   Observe: Fan not spinning or making grinding noises
   Means: A faulty fan restricts airflow, causing overheating and noise.
   Next: Replace the condenser fan motor if it's damaged or not working.
3. Check Evaporator Fan
   Do: Remove the freezer panel and inspect the evaporator fan for obstructions or damage.
   Observe: Fan not spinning or frozen with ice
   Means: A blocked or broken fan prevents cold air circulation.
   Next: Defrost the evaporator coil and replace the fan motor if necessary.
4. Verify Compressor Operation
   Do: Listen for the compressor running. Feel the top of the fridge for vibrations.
   Observe: Compressor is running but fridge isn't cooling
   Means: The compressor may be failing or the refrigerant could be leaking.
   Next: Check for refrigerant leaks or contact a professional for further diagnosis.
5. Test Temperature Settings
   Do: Ensure the temperature settings are set correctly (typically 37°F for fridge and 0°F for freezer).
   Observe: Settings are too high or incorrect
   Means: Improper settings can cause inadequate cooling.
   Next: Adjust the settings and monitor cooling performance over the next 24 hours.
6. Check Door Seals
   Do: Inspect the door gaskets for cracks or gaps. Close the door on a piece of paper to test the seal.
   Observe: Air leaks around the door or paper slides out easily
   Means: Poor seals allow warm air to enter, reducing cooling efficiency.
   Next: Replace the door gaskets if they are damaged or not sealing properly.

Common causes

Parts matching

Common parts needed to fix a noisy, non-cooling fridge:

• Condenser fan motor
• Evaporator fan motor
• Door gasket replacement kit
• Condenser coil cleaning brush
• Thermostat replacement

Always match part numbers to your refrigerator model for compatibility.

When to call a professional

• The compressor is running but the fridge still doesn't cool after checking all components
• You suspect a refrigerant leak (requires professional handling)
• You hear loud knocking or rhythmic noises from the compressor
• The fridge is under warranty and you don't want to risk voiding it
• You're unsure about diagnosing or replacing internal components safely
