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

Safety first: Unplug the freezer before adjusting components.

• 1. Level the unit: Adjust leveling feet so the freezer is stable and does not rock when pushed.
• 2. Tighten mounting hardware: Check compressor mounting bolts and brackets. Tighten gently; do not overtighten rubber grommets.
• 3. Isolate tubing: Identify any copper lines that move and hit the cabinet when the compressor starts or stops. Carefully reposition them and add foam sleeves or clips to prevent contact.
• 4. Monitor over time: Some start/stop noise is normal. If the noise worsens or is accompanied by cooling issues, consult a technician to evaluate the compressor.
