Café Compressor or Line Vibration Noise

Freezer makes a loud banging or knocking sound when the compressor starts or stops.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose compressor mounting hardware, Refrigerant lines striking the cabinet, Internal compressor mechanical wear.

Safety first: Unplug the freezer before working around the compressor area.

Check mounting hardware: Inspect the compressor mounting bolts and rubber grommets. Tighten any loose bolts and replace any cracked or missing grommets.
Isolate tubing: Identify any copper lines that move or strike the cabinet when the compressor starts or stops. Gently reposition them and use foam or clips to prevent contact with the cabinet.
Monitor operation: If the noise persists but cooling is normal, it may be due to internal compressor wear. This is generally not repairable and would require compressor replacement by a professional if the issue worsens.
