Build-Up on Sensor Bars: Accumulation of residue on the sensor bars can cause inaccurate readings.
Wiring Issues: Any loose or damaged wiring can lead to sensor errors.

Fixes for HS Error Code:

Clean Sensor Bars: Use a damp cloth to wipe down the sensor bars located inside the dryer drum.
Inspect Wiring: Check for any visible issues with wiring connected to the sensor.
Reset the Dryer: Unplug the dryer for several minutes, then plug it back in to reset the system.
Replace Sensor: If cleaning and resetting don’t work, the humidity sensor may need replacement.

Flow Sense Indicator and Troubleshooting

The Flow Sense indicator signals airflow problems in your dryer. Addressing this can prevent longer drying times and potential safety hazards.

Causes of Flow Sense Indicator:

Restricted Airflow: Blockages in the ductwork or lint filter.
Vent Hose Issues: Kinks, bends, or improper installation.
Obstructed External Vent: Obstructions in the outside vent opening.

Troubleshooting the Flow Sense Indicator:

Clean Lint Filter: Ensure the lint filter is thoroughly cleaned before each use.
Inspect Vent Hose: Check for kinks, bends, and ensure proper installation.
Clear External Vent: Remove any debris obstructing the external vent.

Turn Off the Dryer: Disconnect the appliance from power.
Clean Internal Components: Focus on the lint filter and the ductwork.
Check and Adjust Vent Hose: Ensure it’s correctly installed without bends or kinks.
Clear Obstructions: Clear any blockages in the external vent for unobstructed airflow.
Run a Test Cycle: After cleaning and checks, run a short cycle to see if the indicator persists.

Regular maintenance, including proper cleaning and checking for blockages, can often prevent these common error codes. If these steps don’t resolve the issue, professional assistance may be required.

When to Call a Professional

Understanding when to call a professional to fix your LG dryer can save you time and prevent further damage. Here are key factors to consider:
