What to check first
Can I keep using it?
Use should be limited to documented owner-level checks or retry steps, not normal operation as a workaround.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Disconnect power before any service-access step.
Do not do this
- Do not use other cycles as a workaround unless the manual allows it.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Recent household power outage or brief supply interruption
- Dryer unplugged or breaker switched while a cycle was active
- Breaker, outlet, or branch-circuit interruption when no outage occurred
Basic checks
- Confirm whether a household outage or deliberate power interruption just occurred; if not, treat PF as unexplained rather than assuming a harmless reset.
- Inspect the visible plug, cord, and outlet from a dry location; if anything is loose, hot, scorched, cracked, or wet, leave the breaker off and call an electrician.
- Check the dedicated dryer breaker from the panel; if it trips again after one reset, leave it off and do not run another cycle.
- Observe the display after power is restored once; if PF returns or the dryer loses power again, stop and arrange service.
Reset or retry steps
- After a confirmed outage and with no damage or hazard signs, unplug the dryer or switch its breaker off, then hold Start/Pause for five seconds while power remains off.
- Restore power once and try one cycle; stop if PF returns, the breaker trips, or power drops again.
When to call a technician
- Use a licensed electrician if PF appears without a known outage, the breaker trips again, or the plug, cord, or outlet shows damage.
- Request LG service if stable household power is confirmed but PF returns or the dryer repeatedly loses power.
- Leave the area and call emergency services for fire, persistent smoke, or active sparking.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
FAQ
What does LG Dryer code PF usually mean?
This code commonly appears when power to the LG dryer was interrupted during operation. Model context matters: LG describes PF as commonly following a power outage; nP and PS are separate electrical-supply displays and are not PF aliases.
Can I keep using the dryer with code PF?
Limit use to the owner-level checks described here and in the model manual. Stop using the appliance if the code returns, the appliance behaves abnormally, or a safety warning applies. Do not keep resetting a breaker that trips again or continue a cycle after repeated power loss.
When should I call a technician for LG PF?
Use a licensed electrician if PF appears without a known outage, the breaker trips again, or the plug, cord, or outlet shows damage. A qualified technician may check Home dryer circuit or outlet, Power cord, Control board power supply, and Dryer wiring harness against the model's service information before treating any part as failed.
