LG Refrigerator Error Code Er HS — Humidity Sensor Error
What this means
The Er HS error code indicates the humidity sensor inside the LG refrigerator is not functioning correctly. This sensor helps regulate moisture levels in the fresh food compartment to keep produce fresh. When it fails, the refrigerator may have excessive moisture, fogging, or condensation issues.
Alternate codes: HS
Step-by-step fix
3 stepsReset the refrigerator
Unplug the refrigerator for 10 minutes and plug it back in. Check if the error code clears. A temporary sensor glitch can cause a false Er HS reading.
Locate the humidity sensor
The humidity sensor is typically located inside the fresh food compartment, often near the crisper drawers or the air vent area. It may be a small rectangular or cylindrical component with a wire connector.
Consult your model's service manual or LG parts diagram for the exact sensor location.
Test and replace the sensor
Unplug the refrigerator. Disconnect the humidity sensor and check for visible damage or corrosion on the connector. If a replacement is available, swap the sensor and see if the error clears.
Condensation dripping onto the sensor connector can cause intermittent Er HS errors.
When to call a professional
If replacing the humidity sensor does not clear the error, the main control board may have a faulty sensor input. A technician can diagnose the control board circuit.
