LG Dryer Error Code PF — Power Failure
What this means
The PF error code means the LG dryer lost electrical power during a running cycle. This is typically caused by a momentary power outage, a tripped circuit breaker, or a loose connection at the outlet or in the electrical panel. The dryer pauses the cycle and displays PF so you can choose to restart.
Step-by-step fix
3 stepsRestart the cycle
Press the Start/Pause button to resume the drying cycle from where it left off, or press Power to cancel and start a new cycle.
Check the circuit breaker
Go to the electrical panel and check the dryer's breaker. For electric dryers, ensure both sides of the double-pole breaker are ON. For gas dryers, check the single breaker for the dryer circuit.
If the breaker trips repeatedly when the dryer runs, there may be an electrical short in the dryer or circuit.
Verify a secure plug connection
Ensure the power cord plug is fully and firmly inserted into the wall outlet. A partially loose plug can cause intermittent power losses.
If the outlet feels loose or the plug doesn't grip firmly, have an electrician replace the outlet.
When to call a professional
If PF errors recur frequently and there are no neighborhood power outages, call an electrician to inspect the circuit. If the dryer itself is causing breaker trips, a dryer technician should check for internal shorts.
