Freezer making rattling or knocking noise when compressor starts or stops

Safety first: Unplug the freezer before touching the compressor or pipework.

Steps:

• Check leveling: Ensure the freezer is level and stable.
• Tighten mounts: At the rear, gently tighten the compressor mounting bolts if they are visibly loose (do not overtighten).
• Secure tubing: Use foam pads or cable ties (heat-resistant) to prevent pipes from knocking against each other or the cabinet.
• Internal items: Make sure food packages are not touching the internal fan cover or panels, which can cause rattling.
