Freezer makes a rattling or clanking noise when the compressor starts or stops.

Safety first: Unplug the freezer before adjusting any components.

• Check external items: Ensure nothing is stored on top of or behind the freezer that could rattle when it runs.
• Secure tubing and coils: At the rear, gently press on copper tubing and condenser coils. If they move and rattle, secure them with foam pads or cable ties, avoiding kinks.
• Inspect compressor mounts: Tighten any loose compressor mounting bolts and replace worn grommets.
• Check evaporator fan: Inside the freezer, remove the rear panel and ensure the fan blades are not contacting ice or wiring. Clear ice and reposition wires as needed.
