Freezer is making a loud buzzing or humming noise near the compressor area.

Safety: Unplug the freezer before working near moving parts.

Steps:

• Access rear compartment: Remove the lower rear panel to expose the compressor and condenser fan.
• Inspect fan: Look for debris in the fan blades or contact with wiring or shrouds. Clear obstructions and secure wiring.
• Check fan motor: If the noise clearly comes from the fan and it wobbles or feels rough when spun by hand, replace the condenser fan motor.
• Compressor mounts: Inspect rubber grommets under the compressor. Replace if cracked or missing to reduce vibration noise.
• Compressor noise: If the compressor itself is loud or knocking, it may be failing. Operation may continue for some time, but replacement requires a sealed system technician.
