What's Happening

The PF (Power Failure) code appears when the dryer detects that power was interrupted during a running cycle — typically from a tripped breaker, a momentary power outage, or someone accidentally unplugging the unit. The code is informational: the dryer is telling you a cycle did not complete. On most models, the PF code also appears at initial startup if there was a power disruption since the last cycle. The dryer itself is almost always fine.

How to Fix It

Press the Start/Pause button to resume the interrupted cycle, or press Power to clear the code and start a new cycle. If PF appears frequently, check your home's circuit breaker for the dryer circuit — electric dryers require a dedicated 240V/30A double-pole breaker. A loose breaker, faulty outlet, or undersized wiring can cause repeated power drops. Have an electrician inspect the circuit if the issue recurs.

Frequently Asked Questions
What does PF mean on an LG dryer?
PF stands for Power Failure. It simply means the dryer lost power while a cycle was running. The dryer itself is not broken — press Start to resume the cycle or Power to clear the code and begin fresh.
Why does my LG dryer keep showing PF?
Recurring PF codes usually point to a problem with the electrical supply rather than the dryer. Check whether the 30A dryer breaker is tripping or loose, and inspect the 4-prong outlet for loose connections. A dedicated 240V circuit with a secure breaker is required for electric dryers.
Do I need to repair anything for a PF code?
Usually not. A single PF code after a storm or power blip requires no repair — just restart the dryer. Only investigate further if PF appears repeatedly without an obvious power event.
