How do I fix error code FS E on a LG refrigerators?

1. undefined: Check CON5 pins 12–11 for loose or disconnected connector; reconnect if needed. 2. undefined: Measure sensor resistance at CON5 pins 12–11: -22°F/-30°C = 40kΩ, -13°F/-25°C = 30kΩ, -4°F/-20°C = 23kΩ, 5°F/-15°C = 17kΩ, 14°F/-10°C = 13kΩ, 23°F/-5°C = 10kΩ, 32°F/0°C = 8kΩ. 3. undefined: If resistance is 0Ω (shorted): replace freezer sensor. 4. undefined: If resistance is OL/∞ (open): replace freezer sensor. 5. undefined: If resistance is normal and matches temperature-resistance table: explain to customer (no fault present).

How to Fix

1
Check CON5 pins 12–11 for loose or disconnected connector; reconnect if needed.
2
Measure sensor resistance at CON5 pins 12–11: -22°F/-30°C = 40kΩ, -13°F/-25°C = 30kΩ, -4°F/-20°C = 23kΩ, 5°F/-15°C = 17kΩ, 14°F/-10°C = 13kΩ, 23°F/-5°C = 10kΩ, 32°F/0°C = 8kΩ.
3
If resistance is 0Ω (shorted): replace freezer sensor.
4
If resistance is OL/∞ (open): replace freezer sensor.
5
If resistance is normal and matches temperature-resistance table: explain to customer (no fault present).
