How to Fix / Troubleshooting
Safety first: Unplug the unit before working near sensors.
Steps to restore bin detection:
- Clean sensor area: Remove ice and wipe the bin full sensor (IR windows or mechanical arm) clean.
- Check alignment: Ensure the bin is correctly positioned and the sensor has a clear line of sight or proper mechanical engagement.
- Remove reflective liners: Avoid using shiny liners or bags in the bin that can reflect IR beams.
- Test sensor: Manually block the sensor or lift the bin arm while the unit runs to see if it stops. If not, the Tristar bin full sensor assembly or control board may need replacement.
