What PF means

On LG electric, gas, heat-pump, and steam dryers, PF means the dryer lost power during operation. It usually appears after an outage or a tripped breaker, when the cycle was interrupted. The dryer is telling you it was cut off, and the cycle did not finish. The fix is a reset, and a dryer that behaves normally afterward needs nothing more.

Common causes of PF

A power outage or a brief dip in supply
A breaker that tripped during a cycle
A loose cord or outlet connection
A control board that did not recover after the interruption

✓ One safe check you can try

1. Unplug the dryer or switch its breaker off. 2. With the power off, press and hold START/PAUSE for 5 seconds. 3. Restore power and run a cycle. 4. If you are unsure the breaker is the cause, tell us what happened before the code appeared.

! Why to stop there

If PF returns without any outage, something is cutting power during the cycle, and we trace it from the outlet inward.
A reset that never holds can point to the control board, which we confirm before replacing it.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

PFPF questions

Why did PF appear after a storm?

PF means the dryer lost power while running. Outages and brief drops leave the display with this message until you reset it. The interrupted cycle did not finish, so start a fresh one after the reset.

How do I reset my LG dryer after PF?

Cut power, hold START/PAUSE for 5 seconds with the power off, then restore power and start a cycle. That sequence clears the message in most cases.

What if PF keeps coming back?

Repeated PF without an outage points to a breaker, outlet, cord, or board problem. We trace where the power is dropping. It helps us to know whether lights flickered or a breaker tripped.
