Error Code 1E

Freezer temperature sensor failed or disconnected

Moderate

Address soon - your appliance may not work properly

Also displayed as: 1E

What This Means

Sensor housing connector separated or loose; Wire open-circuited or short-circuited; Defective thermistor

What actually causes this:

The wire connector to the freezer sensor has pulled loose, or the thermistor itself has failed open or short. Cold and vibration over time cause connector fatigue.

First Thing to Check

Open the freezer evaporator cover and visually inspect the sensor connector — push it firmly home.

Parts Involved

Freezer thermistor (DTN-C502 type)Main PCB CN30

How to Fix

  1. 1

    Enter self-diagnostic mode (Freezer + Control Lock held 10 seconds)

  2. 2

    Measure voltage at Main PCB CN30 pins 1 and 8 — should be 1.0V to 4.5V

  3. 3

    Compare measured voltage to temperature/resistance table on page 107

  4. 4

    If voltage is out of range, inspect wiring and connector, then replace sensor if needed
