What Does Error Code PF Mean on a LG Oven?

Power failure — unit lost power during operation (not a fault).

PF is the control board's record that supply voltage was interrupted mid-operation, then restored. When power returns, the board detects that a cooking or clock program was running and posts PF to flag the interruption rather than a component fault. It differs from sensor or communication codes (like Sb) because no hardware is failing — the board is simply reporting an unstable or momentarily lost power feed to the terminal block.

Models affected: LG electric and gas ranges with a digital display, including models such as LREL6325F and LRGL5825F

What owners report: Owners commonly report PF after a storm, a brief outage, or a breaker trip, and it typically clears with a single press of Clear/Off. If it keeps returning without any obvious outage, people often trace it to a loose terminal-block connection or a weak breaker.

Frequently Asked Questions

Can I keep using my LG Oven when error PF appears? +

Usually yes — PF is a low-severity power notice that rarely stops the oven from working, but clearing the underlying cause prevents it from escalating.

What most commonly causes PF on a LG Oven? +

Across reported LG oven repairs, the most frequent is brief power outage (70% of cases), tripped breaker (20%), then loose power connection (10%). Check them in that order before replacing any parts.

PF keeps coming back after a reset — what should I check next? +

A reset only clears the stored PF fault; if it returns, the power problem is still present. Move on to the physical checks — clear the code, then check the breaker — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.

How much does it cost to fix LG Oven error PF? +

A DIY repair typically runs $0–$0 in parts, versus $0–$150 for a professional service call. Expect the work to take about 10–20 minutes.

Which LG Oven models show error PF? +

PF is documented on LG electric and gas ranges with a digital display, including models such as LREL6325F and LRGL5825F. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
