LG Oven Error PF: Power Failure — Cycle Interrupted

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The oven experienced a power interruption mid-cycle. PF is an informational alert letting you know the last cooking cycle did not complete due to a power cut. The clock will also need to be reset.

Severity

Low - usually safe to check with basic user-accessible cleaning or inspection on the LG oven.

Can you fix it yourself?

Yes — DIY-safe

Most likely cause

Brief household power outage during a cooking cycle

Estimated time for safe first checks: 1–2 min to clear and reset clock.

Step-by-Step DIY Fix Guide

  1. SAFETY: No electrical hazard. PF is an informational code.
  2. Press the Clear/Off button to dismiss the PF alert.
  3. Reset the clock — press the Clock button, enter the correct time, and confirm.
  4. Restart the cooking cycle if needed.
  5. If PF appears repeatedly without an obvious power outage, confirm the range is plugged directly into a 240V wall outlet (not an extension cord) and that the outlet is stable.

If the door warning comes back

  • If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
  • PF appears repeatedly across multiple days with no household power outages

What This Error Means

Error PF on your LG oven means: The oven experienced a power interruption mid-cycle. PF is an informational alert letting you know the last cooking cycle did not complete due to a power cut. The clock will also need to be reset. The range's self-diagnostic system has detected this condition.

The most frequent cause is brief household power outage during a cooking cycle. Work through the causes and fix steps below in order — many LG oven errors are resolved without a service call.

Error PF is DIY-safe. No tools are required and the fix typically takes under 10 minutes. Follow all steps in sequence.

Electric ranges require a stable 240V dedicated circuit. A partially tripped breaker — where one leg of the double-pole breaker has tripped but not the other — is a common and easily overlooked cause of voltage errors. Fully toggle the breaker off and on before investigating further.

Most Likely Cause by Symptom

The LG oven may stop, pause, or refuse to complete the cycle normally.

Likely cause: Brief household power outage during a cooking cycle

Check first: SAFETY: No electrical hazard. PF is an informational code.

Common Causes

  • Brief household power outage during a cooking cycle
  • Circuit breaker tripped while the range was in use
  • Momentary power interruption from the utility company

What Not to Do

  • Do not leave food in the oven after PF without restarting the cycle — the oven has stopped heating and food may have cooled to an unsafe temperature if the outage was long

Model and Display Variation Notes

Model-family notes

  • LG oven display wording and code formats can vary by series.
  • If your model behaves differently, check the owner manual before trying any deeper maintenance step.

Display and panel differences

  • Panel wording can vary by series, so confirm the exact code pattern before buying parts.

Parts, Tools and Service Options

Manual and model check

Check your exact model and manual before ordering any LG oven parts.

This section stays model-first because exact manual and parts matching matters more than a generic replacement suggestion here.

When Not to Keep Troubleshooting

PF appears repeatedly across multiple days with no household power outages

How to Prevent It Recurring

  • Ensure the range is on a dedicated 240V circuit — sharing the circuit with other high-draw appliances can cause momentary voltage drops that trigger PF
