LG Dryer Error Code IF — Lint Filter Assembly Problem
What this means
The IF error code indicates the dryer cannot detect the lint filter in its proper position. On some LG models, the lint filter consists of two parts (an exterior filter and an interior filter) that both must be correctly assembled and in place. A missing inner filter, a misaligned filter, or a faulty filter detection switch can trigger this code.
Step-by-step fix
2 stepsCheck filter assembly
Remove the lint filter and ensure both the inner and outer filter components are present and properly assembled. Reinsert firmly into the dryer.
On WashTower models, the lint filter has an interior magnet that triggers the detection switch. Make sure the magnet area is clean.
Inspect for damage
Check the filter frame for cracks, warping, or missing tabs that prevent it from sitting correctly in the housing.
When to call a professional
If the filter is properly assembled and the error persists, the filter detection switch may need replacement.
