How to Fix / Troubleshooting

Safety First: Unplug the unit before accessing the bin area.

Steps to resolve E19:

Locate bin sensor: Find the bin thermostat or temperature sensor, usually mounted on or near the ice storage bin wall.
Check mounting: Ensure the sensor or bulb is firmly attached to the bin surface and not hanging loose.
Inspect wiring: Follow the wires back to the control board, checking for damage or loose connectors.
Test thermostat: Disconnect and test for continuity at different temperatures (e.g., room temperature vs. cooled with ice). Replace if readings are not as specified.
Replace bin thermostat: Install a new Koldfront-compatible bin thermostat or sensor and secure it in the original location.
Test: Restore power and monitor operation to ensure E19 is cleared and bin temperature is controlled.

Display shows E19; ice maker may start but then stops with no ice in the bin.
