Freezer displays E19, which may indicate an open sensor circuit.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Broken thermistor lead, Unplugged sensor connector, Broken wire in the cabinet harness, Failed control board pull-up circuit

Safety first: Disconnect power before handling any wiring.

Locate the indicated sensor: Use the technical sheet to identify which thermistor is associated with E19.
Check the connector: Ensure the sensor connector is fully seated at both ends. Reseat it if loose.
Perform a continuity test: With the sensor disconnected at both ends, test continuity through the harness. Repair or replace it if open.
Test the thermistor: Measure resistance directly at the sensor. If it reads OL (open circuit), replace the thermistor.
Replace the control board: If the sensor and harness are intact but E19 persists, replace the main control board.
