- 1Sensor failure
Step-by-Step Troubleshooting
- 1
Locate the humidity sensor inside the fresh food compartment — typically mounted near the crisper drawer air vent
- 2
Remove the sensor and inspect for moisture film or condensation on the sensor element that could cause false readings
- 3
Gently clean the sensor element with isopropyl alcohol and a lint-free cloth, allow to dry completely before reinstalling
- 4

- 5
If cleaning does not resolve the error, replace the humidity sensor module
Pro Diagnostic Tip
Sacramento and Bay Area homes with higher humidity levels can trigger Er HS more frequently. The sensor controls the moisture retention system in LG crisper drawers — a failed sensor defaults to maximum dehumidification, causing produce to dry out faster.
