How to Fix / Troubleshooting
Safety: Unplug before inspecting wiring or the control board.
Steps:
- Stable outlet: Plug the Antarctic Star ice maker directly into a dedicated wall outlet. Avoid power strips or surge protectors that may limit current.
- Inspect cord and plug: Ensure the plug fits snugly in the outlet and the cord is not damaged.
- Board inspection: Remove the cover over the control board and look for burnt spots, cracked solder joints, or swollen components. If found, replace the board.
- Professional diagnosis: If the issue persists, a technician can test line voltage stability and board operation under load.
