LG oven displays PF and beeps after a power interruption; clock may reset.

Safety first: If you suspect wiring damage, contact an electrician.

• Clear code: Press any key or follow the display prompt to clear PF. Reset the clock.
• Check breaker: Ensure the range breaker is fully ON and not loose.
• Inspect cord and outlet: With power OFF, verify the range cord is firmly plugged in and the outlet is secure. Look for signs of heat damage.
• Monitor: If PF recurs frequently without known outages, have an electrician check the circuit for loose connections or voltage drops.
