Possible Causes

Blown internal line fuse, Failed EMI power filter, Loose power cord connection inside cabinet, Damaged main power harness

How to Fix / Troubleshooting

Safety first: Unplug the ice maker before opening any panels. Capacitors in the filter can hold charge; avoid touching bare terminals.

Steps:

  • Check cord entry: Remove the rear lower panel and inspect where the power cord enters the unit. Ensure strain relief is intact and wires are not pulled loose.
  • Inspect EMI filter: Locate the EMI/power filter module. Check for burn marks or bulging. Replace if visibly damaged.
  • Test internal fuse: Find the inline or board-mounted fuse and test for continuity. Replace with the exact same type and rating if open.

Note: If the new fuse blows immediately, there is likely a short in the wiring or components that requires professional diagnosis.
