Ice maker starts a cycle but stops after filling with water; no further actions occur.

Safety first: Unplug the unit before inspecting internal components.

Steps to troubleshoot mid-cycle stops:

• 1. Perform a hard reset: Unplug the ice maker for at least 15 minutes, then plug it back in and start a new cycle.
• 2. Check water level sensor: Ensure the float and switch correctly indicate that the reservoir is filled; a bad signal can halt the program.
• 3. Inspect PCB connections: Reseat all connectors on the main control board, especially those from sensors and the pump.
• 4. Replace main PCB: If the unit consistently hangs at the same point despite good sensors, the control board logic may be faulty and require replacement.

Note: Document the exact point in the cycle where it stops; this helps in diagnosing which signal is missing.
