Possible Causes
Broken or stuck bin full arm, Failed infrared bin sensor, Sensor wiring shorted, Control board not responding to full signal
How to Fix / Troubleshooting
Safety: Unplug the unit before inspecting the bin area.
Steps:
- Check mechanical arm: If your model uses a bin arm, ensure it moves freely and is not jammed by ice. Replace if broken.
- Inspect IR sensors: For infrared systems, clean the emitter and receiver lenses and ensure they are aligned.
- Test sensor: With a multimeter, check continuity or voltage changes when the bin is full vs. empty (refer to service data). Replace the sensor if it does not change state.
- Control board: If the sensor works but the unit ignores the full condition, the main control PCB may be faulty.
Warning: Do not disable the bin full sensor; overfilling can damage the unit and cause leaks.
