Ice maker is running but makes a loud grinding or rattling noise.

Safety First: Disconnect power before placing hands near any moving parts.

• Identify noise source: Remove the front grille and rear panel (if accessible) and briefly power the unit to locate whether the noise comes from the fan, pump, or compressor area.
• Check for obstructions: Look for ice, insulation, or wiring contacting the condenser fan blades. Clear any obstructions.
• Tighten hardware: Tighten loose screws on fan brackets, pump mounts, and panels.
• Replace noisy component: If the noise is internal to the fan motor or pump and persists, replace the condenser fan motor or water circulation pump as appropriate.
