What Does Error PF Mean?

The LG dryer PF error code indicates a power failure or interruption detected by the appliance. This often results in the dryer unexpectedly stopping mid-cycle, with the display flashing or turning off. The PF code can appear immediately after a power fluctuation, and it suggests issues like power outages, voltage irregularities, or loose connections.

Common Symptoms:

  • PF appears on display instead of a numeric code
  • Dryer stops or won’t start after a power interruption or fluctuation
  • Code appears immediately upon powering the dryer back on

Possible Causes

  • Power outage / interruption (temporary loss of electrical supply) (medium)
  • Voltage irregularity (supply voltage too high or too low) (medium)
  • Loose power cord or outlet connection (low)

How to Fix Error PF

DIY Fix Check and stabilize power supply

  1. Turn off and unplug the dryer from the wall outlet.
  2. Check the outlet and plug for visible damage or loose connections.
  3. Plug the dryer back in securely and restart the dryer.
  4. If the PF code persists, try a different outlet on a dedicated circuit.

Technician Only Evaluate electrical supply and internal wiring

  1. Measure the household supply voltage to ensure it falls within acceptable range for the dryer.
  2. Inspect the dryer’s power cord, terminal block, and internal wiring for signs of wear, loose connections, or damage.
  3. Check for intermittent power supply issues at the breaker panel.
  4. If power supply and wiring are confirmed good but PF persists, test the main control board for faults.
