What Does Error Code PF Mean on a LG Dryer?

Power failure — cycle interrupted.

The PF (Power Failure) code appears when the control board detects that supply voltage was interrupted mid-cycle and then restored. Rather than silently resuming, the board flags that the drying cycle stopped before completion, so clothes may remain damp. It is an informational notice, not a component fault — unlike sensor or motor error codes, no part has failed. It commonly follows a brief outage, a momentary voltage dip, or a tripped breaker on the dryer's dedicated circuit.

Models affected: LG electronic-control dryers with a digital display (both electric and gas models), across most modern model lines
What owners report: Owners commonly report PF showing up after a storm, a flicker in the lights, or when the dryer shares a circuit that briefly overloads. It usually clears the moment you press Start again, so a repeat appearance may point to a loose cord connection or a weak breaker worth checking.

Frequently Asked Questions

Can I keep using my LG Dryer when error PF appears? +
Usually yes — PF is a low-severity power notice that rarely stops the dryer from working, but clearing the underlying cause prevents it from escalating.
What most commonly causes PF on a LG Dryer? +
Across reported LG dryer repairs, the most frequent is power outage during cycle (90% of cases) then circuit breaker tripped (10%). Check them in that order before replacing any parts.
PF keeps coming back after a reset — what should I check next? +
A reset only clears the stored PF fault; if it returns, the power problem is still present. Move on to the physical checks — restart cycle, then check circuit breaker — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.
How much does it cost to fix LG Dryer error PF? +
A DIY repair typically runs $0–$0 in parts, versus $0–$0 for a professional service call. Expect the work to take about 10–20 minutes.
Which LG Dryer models show error PF? +
PF is documented on LG electronic-control dryers with a digital display (both electric and gas models), across most modern model lines. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
