How to Fix / Troubleshooting

Step 1 – Identify noise source:

Listen carefully to determine if the noise comes from inside, back, or bottom of the refrigerator.

Step 2 – Level the refrigerator:

Use a bubble level on top of the unit.
Adjust the front leveling legs so the refrigerator is slightly tilted back and does not rock.

Step 3 – Check interior items:

Ensure glass bottles or containers are not touching each other or the walls.
Rearrange items to reduce vibration.

Step 4 – Inspect condenser fan (back/bottom noise):

Unplug the refrigerator and remove the rear lower access panel.
Check the Condenser Fan Motor for debris or loose mounting.
Tighten screws and remove any obstructions.

Step 5 – Compressor noise:

Some humming and clicking is normal; loud knocking may indicate internal compressor issues.
If noise is clearly from the compressor shell, contact a technician; compressor replacement is not a DIY repair.
