LG Dryer PF error code

Difficulty: Easy · Cost: $0 · Duration: 2–5m

The PF error means your LG dryer lost power during a running cycle. This is most commonly caused by a power outage or a tripped circuit breaker. The dryer displays PF to let you know the cycle did not complete normally. A factory reset by holding the Start/Pause button while the unit is unplugged clears it in most cases. If PF keeps appearing after the reset the unit will need a professional repair.

Common causes

  • Power outage interrupted the cycle while the dryer was running
  • Circuit breaker for the dryer tripped during the cycle
  • Dryer was accidentally unplugged while running
  • Unstable power supply causing a temporary interruption

  4. 4
