What Does Error Code Er HS Mean on a LG Refrigerator?

Humidity sensor error.

The control board cannot get a valid reading from the humidity sensor, which it uses to manage anti-condensation heaters and damper/airflow control. With the sensor out of range the board defaults its humidity logic, which can lead to sweating around door mullions or inconsistent compartment control. A failed sensor or a loose connector is the usual cause.

What Causes Error Code Er HS?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Humidity sensor failed 60% of cases
  2. 2
    Connector loose or corroded 25% of cases
  3. 3
    Harness damage 10% of cases
  4. 4
    Control board input fault 5% of cases

Frequently Asked Questions

Can I keep using my LG Refrigerator when error Er HS appears? +
Usually yes — Er HS is a low-severity sensor notice that rarely stops the refrigerator from working, but clearing the underlying cause prevents it from escalating.
What most commonly causes Er HS on a LG Refrigerator? +
Across reported LG refrigerator repairs, the most frequent is humidity sensor failed (60% of cases), connector loose or corroded (25%), then harness damage (10%). Check them in that order before replacing any parts.
Er HS keeps coming back after a reset — what should I check next? +
A reset only clears the stored Er HS fault; if it returns, the sensor problem is still present. Move on to the physical checks — power cycle, then reseat the sensor connector — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix LG Refrigerator error Er HS? +
A DIY repair typically runs $20–$55 in parts, versus $140–$280 for a professional service call, so handling it yourself saves around $120. Expect the work to take roughly 30–60 minutes.
