LG Dryer PF — Power Failure during cycle
LG Dryer · Error code PF
What PF Means
PF indicates the dryer lost AC power mid-cycle and resumed when power returned. It is informational, not a hardware fault, but it can mask an intermittent power problem if it recurs often.
Symptoms
- PF shown after a power blip
- Cycle stopped partway through
- Display flashing on resume
Common Causes
Grid sag or momentary outage interrupted the cycle.
240V breaker tripped and was reset.
Dryer cord vibrated partially out of the outlet.
Heat-damaged terminal causes intermittent dropout.
How to Fix It
- Press Start/Pause to clear PF and resume.
- If PF returns, unplug the dryer for 60 seconds, then plug back in to factory-reset.
- Check the 30A double-pole breaker in the panel — reset if tripped, replace if it trips repeatedly.
- Inspect the cord and outlet for heat discoloration, scorch marks, or loose lugs and replace any damaged parts.
