What to check first
Use should be limited to documented owner-level checks or retry steps, not normal operation as a workaround.
Basic checks
- Confirm whether a known outage or deliberate interruption occurred and that household power is stable. Treat unexplained PF as a reason for qualified electrical assessment, not repeated resets.
- From a dry safe position, observe only the exposed plug, cord and outlet for heat, looseness, scorching, cracks or moisture. Keep clear and seek qualified help for any hazard.
- Use the documented unpowered control procedure below only when it matches the exact model and no damage, gas smell, overheating, blocked exhaust or electrical warning is present.
Applicability
Regional guidance · LG dryers that display PF after power interruption · United States
LG describes PF as an outage-related display, but repeated or unexplained power loss must be treated as an electrical fault until the exact installation is checked.
Reset or retry steps
- LG’s PF section directs unplugging the dryer or switching off its dedicated breaker, holding Start/Pause for five seconds while it remains without power, then restoring power and trying a cycle. Do not press through an energized reset or omit the power-off condition.
- FaultCodeLab limits the applicable safe procedure to one attempt. Stop and request qualified service if PF persists, returns, the breaker trips or power is lost 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.
Can I keep using it?
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
- LG commonly associates PF with a power outage. An unexplained or recurring power loss is not proof of a harmless supply event or a particular failed part.
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 the listed symptoms and source guidance against the model's service information before treating any part as failed.
