Freezer makes loud banging or rattling noises when the compressor starts or stops.

Safety: Unplug the freezer before adjusting mounts or accessing the compressor area.

Steps:

• Level the cabinet: Use a level and adjust the front feet so the freezer is stable and does not rock when pushed.
• Check internal items: Ensure shelves, baskets, and food items are not vibrating against each other or the liner. Rearrange as needed.
• Inspect compressor mounts: Remove the rear lower panel and check that the compressor mounting bolts or rubber grommets are intact and snug. Tighten loose bolts gently; do not overtighten and crush the grommets.
• Secure tubing: If copper lines jump or hit the cabinet at startup, add foam padding or clips to hold them away from contact points.
• Test operation: Restore power and observe several start/stop cycles to confirm noise reduction.
