How do I fix error code IS E on my LG LRFS28XBD?

1. undefined: Check CON101 pins 4–2 for loose or disconnected connector; reconnect if needed. 2. undefined: Measure icing sensor resistance at CON101 pins 1–2: -22°F/-30°C = 40kΩ, -13°F/-25°C = 30kΩ, -4°F/-20°C = 23kΩ, 14°F/-10°C = 13kΩ, 23°F/-5°C = 10kΩ, 32°F/0°C = 8kΩ. 3. undefined: If resistance is 0Ω (shorted): replace icing sensor. 4. undefined: If resistance is OL/∞ (open): replace refrigerator (icing sensor/ice maker assembly). 5. undefined: If resistance is normal and matches table: explain to customer.

How to Fix

1
Check CON101 pins 4–2 for loose or disconnected connector; reconnect if needed.
2
Measure icing sensor resistance at CON101 pins 1–2: -22°F/-30°C = 40kΩ, -13°F/-25°C = 30kΩ, -4°F/-20°C = 23kΩ, 14°F/-10°C = 13kΩ, 23°F/-5°C = 10kΩ, 32°F/0°C = 8kΩ.
3
If resistance is 0Ω (shorted): replace icing sensor.
4
If resistance is OL/∞ (open): replace refrigerator (icing sensor/ice maker assembly).
5
If resistance is normal and matches table: explain to customer.
