What Does Error Er 1E Mean?

The LG refrigerator error code Er 1E indicates a temperature sensor fault, particularly in the freezer compartment. This error often leads to inconsistent cooling and improper freezer temperatures, making it crucial to address for optimal performance. Common causes include a faulty temperature sensor or frost buildup around the thermistor, which may cause inaccurate readings.

Common Symptoms:

  • Error "1E" displayed on the fridge panel indicating a problem with temperature sensing or cooling regulation
  • Refrigerator fails to maintain proper freezer temperature

Possible Causes

  • Freezer temperature sensor fault or connection issue (medium)
  • Frost or ice buildup around the freezer thermistor causing false readings (medium)

How to Fix Error Er 1E

DIY Fix Basic reset and preliminary check

  1. Unplug the refrigerator power for approximately 5 minutes.
  2. Plug the refrigerator back in and see if the 1E error clears.
  3. Ensure that freezer and fridge doors are fully closed and that the unit is level.

Technician Only Inspect and test freezer temperature sensor and wiring

  1. Disconnect power to the refrigerator.
  2. Remove the freezer interior rear panel to access the freezer thermistor.
  3. Inspect wiring harness for loose, corroded, or damaged connectors.
  4. Melt any frost/ice around the thermistor and reseat the connector.
  5. Test the thermistor with a multimeter to verify proper resistance values as per model specs and replace if faulty.

Parts needed: freezer temperature sensor (thermistor), wiring harness connectors

🛑 When to Call a Pro:
  • If the error persists after reset and basic frost removal.
  • If sensors test out of spec or wiring appears damaged.
  • If the refrigerator fails to cool correctly or temperatures remain unstable.
