If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the freezer before reaching into the compressor compartment. Metal edges can be sharp.
- Inspect mounting: Check that the compressor is firmly mounted on rubber grommets. Replace any cracked or missing grommets.
- Secure tubing: Look for copper lines touching each other or the cabinet. Gently bend or pad them with foam to prevent contact and vibration.
- Tighten loose parts: Tighten any loose brackets, panels, or fan shrouds that may resonate.
If the compressor itself is internally noisy (knocking or grinding), it may be failing and should be evaluated by a refrigeration technician.
