Display shows PF and oven beeps after a power interruption; clock may reset.

Safety first: If you suspect wiring issues, turn off power at the breaker before inspection.

• Confirm household power: Check that other appliances and lights on the same circuit are working properly.
• Reset clock: Press Clear/Off or similar key, then set the time. If PF does not return, no further action is needed.
• Inspect power cord and outlet: For slide-in or freestanding LG Studio ranges, ensure the cord is firmly connected to the terminal block and the outlet is secure.
• Check breaker: Make sure the double-pole breaker is fully ON and not weak or tripping frequently.
• If PF recurs without outages: Have an electrician check the supply voltage and connections; intermittent power can damage the control board.

Note: PF itself is not a component failure code; it indicates a power event.
