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

1. undefined: Check for loose connection at CON4 on main PCB 2. undefined: Unplug connector from CON4 3. undefined: Check resistance between Red/Yellow to Yellow wires 4. undefined: If 0 Ohm (short circuit): replace the humidity sensor 5. undefined: If open circuit (infinite resistance): replace the refrigerator 6. undefined: If reading is in normal range, compare to temperature table: at -22F/-30C expect 40.5-38.5 kOhm; at -13F/-25C expect 30.5-28.5 kOhm; at -4F/-20C expect 23-21.5 kOhm; at 5F/-15C expect 17.5-16.5 kOhm; at 14F/-10C expect 13.5-12.5 kOhm; at 23F/-5C expect 10.5-9.5 kOhm; at 32F/0C expect 8-7.5 kOhm

Error Code E HS

Q: What does error code E HS mean on a LG refrigerators?

Humidity Sensor Error Short circuit on humidity sensor wiring; Open/disconnected humidity sensor wiring; Loose connection at CON4 on main PCB

Humidity Sensor Error

Moderate

Address soon - your appliance may not work properly

What This Means

Short circuit on humidity sensor wiring; Open/disconnected humidity sensor wiring; Loose connection at CON4 on main PCB

How to Fix

1
Check for loose connection at CON4 on main PCB
2
Unplug connector from CON4
3
Check resistance between Red/Yellow to Yellow wires
4
If 0 Ohm (short circuit): replace the humidity sensor
5
If open circuit (infinite resistance): replace the refrigerator
6
If reading is in normal range, compare to temperature table: at -22F/-30C expect 40.5-38.5 kOhm; at -13F/-25C expect 30.5-28.5 kOhm; at -4F/-20C expect 23-21.5 kOhm; at 5F/-15C expect 17.5-16.5 kOhm; at 14F/-10C expect 13.5-12.5 kOhm; at 23F/-5C expect 10.5-9.5 kOhm; at 32F/0C expect 8-7.5 kOhm
