LG Dryer IF Error Code
What it means
LG's IF guidance indicates that the dryer is not detecting the lint filter correctly; the filter assembly or its interior-filter magnet may be out of place or missing.
Try this first
- Make sure both the exterior and interior lint-filter pieces are assembled correctly and fully seated.
- Check that the magnet in the interior filter is in its proper place.
- If the magnet is missing or its holder is damaged, replace the lint filter.
- If IF remains with the filter correctly assembled, request service.
Can I keep using it?Follow the manufacturer troubleshooting steps and confirm normal operation before returning the appliance to normal use.
Repair usually required?Inspection is recommended if IF remains after the filter and magnet checks.
