Safety first: Unplug the freezer before touching any moving parts. Keep fingers and tools away from fan blades.

Steps to reduce rear noise:

Access rear compartment: Remove the lower back panel to expose the compressor and condenser fan.
Inspect fan: Check if the fan blade is rubbing against wiring, shroud, or insulation. Reposition obstructions and ensure the blade is secure on the motor shaft.
Test fan motor: Spin the blade by hand; it should move smoothly. If noisy or stiff, replace the condenser fan motor.
Listen to compressor: With the panel off and power restored, listen to the compressor. Repeated clicking without sustained running suggests a start device issue; replace the start relay/overload.
Compressor noise: If the compressor is extremely loud or knocking but still cools, it may be wearing out. Only a technician can replace it.

Note: Some low-level humming is normal, but sudden changes in noise level should be investigated.

Freezer makes loud humming, buzzing, or clicking noises from the rear.
