How to Fix / Troubleshooting

Safety: Unplug the freezer before touching any moving parts. Components may be hot.

Steps:

Access rear compartment: Remove the lower rear cover to expose the compressor and condenser fan.
Identify noise source: Run the unit briefly (with caution) to locate whether the noise comes from the fan or compressor. Then unplug again.
Fan issues: Clear any debris from the fan blades and shroud. If the motor is noisy or loose, replace the condenser fan motor.
Compressor vibration: Check rubber mounting grommets. Replace any that are cracked or missing and ensure mounting bolts are snug but not overtightened.
Internal compressor noise: If the compressor itself is excessively loud or knocking, it may be failing and should be evaluated by a professional.

Freezer is making a loud humming or buzzing noise from the back.
