Loud banging or knocking noise when the ice maker cycles.

Safety First: Unplug the unit before adjusting internal components. Some noise from ice dropping is normal, but loud bangs are not.

Steps:

• Secure ice bin: Ensure the bin is fully seated on its rails and not loose. Adjust or replace bin rails if worn.
• Check for large slabs: If ice is forming in large sheets, address overfreezing issues (see oversized ice fault) so ice breaks into smaller pieces.
• Inspect refrigerant lines: Look behind the unit for copper lines touching the cabinet. Gently bend them away and add foam sleeves where needed.
• Check compressor mounts: Verify rubber grommets under the compressor are intact and that mounting bolts are snug but not overtightened.
