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

1. undefined: Step 1: Check connector between Main PCB and icing/ice maker sensor — if loose or disconnected, reconnect or repair at CON3 pins 10-9. 2. undefined: Step 2: Measure resistance at CON3 pins 10-9. If resistance = 0 ohm (short), replace sensor. 3. undefined: Step 3: If resistance = infinity (open), proceed to Step 4. 4. undefined: Step 4: Check temperature vs. resistance using table: -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. If matches, explain to customer. 5. undefined: Step 5: If resistance does not match expected value, replace sensor. 6. undefined: Step 6: If connection abnormal, reconnect or repair connector.

How to Fix

1
Step 1: Check connector between Main PCB and icing/ice maker sensor — if loose or disconnected, reconnect or repair at CON3 pins 10-9.
2
Step 2: Measure resistance at CON3 pins 10-9. If resistance = 0 ohm (short), replace sensor.
3
Step 3: If resistance = infinity (open), proceed to Step 4.
4
Step 4: Check temperature vs. resistance using table: -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. If matches, explain to customer.
