LG dryer PF error code
- Dryer
LG dryer PF means the control detected a power interruption — the display may show PF after a brief outage or tripped breaker. On electric dryers, PF is informational: restore stable power and press Start to clear it. If PF appears every cycle, inspect the terminal block and breaker for loose connections rather than replacing the board.

Safe to keep using?
No safety issue
This is a status or lock code, not a hardware fault.
How to fix PF
- Check the dryer breaker — flip fully OFF then ON on the 30A double-pole breaker.
- Confirm the power cord is firmly seated at the terminal block behind the dryer.
- Press Start or any button to acknowledge PF — most models clear PF once power is stable.
- If PF returns every cycle, inspect the outlet and cord for intermittent voltage drops.
- Replace the cord or terminal block only if you see burn marks or loose neutrals.
Call a pro when: Call an electrician if the breaker trips or voltage is unstable at the outlet.

What PF means
Power failure — the last cycle was interrupted by a power loss.
Likely causes
A brief outage or unplugging the dryer stores PF.
Check: Unplug the dryer, hold Start/Pause for 5 seconds, restore power, then run a cycle.
Est. cost: $0–$0
A loose plug or half-tripped breaker can interrupt power mid-cycle and store the status.
Check: Reseat the cord, reset the breaker fully off then on, and avoid extension cords.
