What PF usually means
PF usually means the dryer detected a power failure or interrupted supply.
Codes can vary by exact LG dryer model number, production year, and regional design. Use this as first-pass guidance, then confirm the model-specific manual or manufacturer support page before opening panels or replacing parts.
First checks
Confirm the plug is fully seated, check whether the breaker tripped, and note any outage or flicker during the cycle.
A one-time outage is different from repeated PF warnings on the same load or circuit.
- Check for recent power interruption.
- Reset a tripped breaker once only.
- Remove extension cords or adapters.
- Use qualified service for outlet testing.
When to stop
Stop if the breaker trips again, the outlet feels warm, or PF returns without an obvious power event.
Keep the full model number, exact PF display text, cycle name, and timing ready before contacting LG support or a qualified technician.
Model numbers affected
Commonly searched model families include electric dryers, gas dryers, vented dryers, heat-pump dryers, and compact laundry models.
This is not a confirmed model-number list. Match the exact code to the full model number on the appliance tag before ordering parts, opening panels, or booking service.
