Unit frequently shows low water or ice full messages even when conditions are normal (intermittent false alerts).

Safety: Disconnect power before accessing internal wiring.

Steps:

• Reseat connectors: Unplug and reattach all sensor connectors (water level, ice full, temperature) on the main PCB.
• Clean contacts: Use contact cleaner on oxidized connectors.
• Stable power: Plug the unit directly into a wall outlet, avoiding power strips with many devices.
• Replace suspect sensors: If one sensor is consistently implicated (e.g., low water), replace that specific sensor assembly.
