LG Range PF Error Code

PF usually records a power interruption rather than identifying a failed oven part. Clear the message once, confirm normal operation, and treat repeated or unexplained power loss as an electrical-supply concern.

Applies to LG range or oven

What the appliance detected

Detected condition

LG says PF means power has been interrupted to the appliance.

What may contribute

Possible causes

  • A recent household outage, breaker trip, or other interruption of power.
  • Power was disconnected during installation, cleaning, or service.
  • A recurring household supply problem if PF returns without a known outage.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the message and power history

    • Photograph PF and note whether the home recently lost power or the range circuit was intentionally switched off.
    • Confirm the full model number so the correct owner manual and control layout can be used.

  2. Clear PF once with the normal controls

    • LG directs owners to press CLEAR/OFF and then retry the original function.
    • If PF reappears, switch the range circuit breaker fully off for 30 seconds and restore power once.

  3. Stop if the interruption is unexplained

    • If PF returns without another known outage, stop repeated resets and note whether lights, outlets, or other appliances also show power problems.
    • For sparking, scorching, burning odor, a hot outlet or cord, or repeated breaker trips, stop using the range and contact a licensed electrician.

Actions not recommended

  • Do not open the range, outlet, junction box, electrical panel, or terminal connections to investigate PF.
  • Do not test live voltage or repeatedly reset a breaker that continues to trip.
  • Do not replace a control board or other part based on PF alone.

When to stop and request service

  • Use a licensed electrician for repeated breaker trips, damaged electrical connections, or unexplained household power interruptions.
  • Request appliance service if the electrical supply is confirmed correct but PF continues to return.
  • Stop immediately for smoke, sparking, scorching, burning odor, unusual heat, or visible electrical damage.
