Ice maker is very noisy during operation (grinding, rattling, or buzzing).

Safety first: Unplug the ice maker before touching moving parts.

Noise reduction steps:

• Identify noise source: With the unit briefly powered, listen near the back (compressor/fan) and front/base (pumps) to localize the sound. Then unplug.
• Check fans: Inspect fan blades for contact with shrouds or wiring. Tighten mounting screws and replace noisy fan motors.
• Inspect pumps: Open pump housings and remove any debris causing grinding. Replace pumps with worn or noisy bearings.
• Secure components: Tighten loose panels, brackets, and compressor mounting bolts. Add foam pads or grommets where tubing vibrates against metal.
