Ice maker stops making ice even though bin is not full

Safety first: Disconnect power before adjusting sensors.

• Step 1 – Break up ice clumps: Remove any large clumps or bridges of ice that may be contacting the sensor.
• Step 2 – Verify sensor position: Ensure the bin sensor is mounted at the correct height and angle per Viking specifications.
• Step 3 – Test sensor: Check thermistor resistance or optical sensor function. Replace if readings are out of range.
• Step 4 – Control board evaluation: If a known-good sensor still causes premature shutoff, the main control board may need replacement.

Monitor operation after repair to ensure ice production resumes and stops only when the bin is truly full.
