Ice maker makes a rattling or vibrating noise, especially during compressor operation.

Steps:

• Verify the Marvel ice maker is level front‑to‑back and side‑to‑side using a bubble level. Adjust the leveling legs as needed.
• Check that the front grille or toe‑kick is securely attached and not vibrating against the floor or cabinet.
• Remove the rear or bottom panel and inspect for copper tubing or wiring harnesses touching the cabinet. Gently bend tubing away and secure with foam or clips.
• Inspect the condenser fan shroud and motor mounts for looseness. Tighten screws and ensure the fan blade does not contact any surfaces.
