What Does Error Code F2 Mean on a LG Oven?

Oven over-temperature — exceeded maximum safe temperature.

The F2 code fires when the control board reads oven cavity temperature above its safe ceiling, generally around 590°F in normal cooking, and cuts power to protect the appliance. It differs from open- or short-sensor faults (often flagged as F1/F3) because the sensor is reporting a genuinely high value or a stuck heating-element relay is feeding the element continuously. The board can't distinguish a drifting sensor from real overheating, so it treats any over-limit reading as a critical shutdown.

Models affected: LG electric and gas ranges with electronic oven controls, including models such as LREL6325F and LRGL5825F

What owners report: Owners commonly report F2 appearing during or shortly after a self-clean cycle, or when the oven keeps heating past its set point. A drifting or miscalibrated temperature sensor is a frequent false trigger, and some report the code clears after a full cool-down and breaker reset—though a stuck relay tends to bring it right back.

What Causes Error Code F2?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

1

Temperature sensor failure causing incorrect readings 40% of cases
2

Heating element relay stuck on control board 35% of cases
3

Control board failure 15% of cases
4

Self-clean cycle issue 10% of cases

How to Fix LG Oven Error Code F2

🔧🔧🔧 Advanced DIY Est. time: 1–3 hours

⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.

1

Power off immediately

Turn off the circuit breaker. Allow oven to cool for 1 full hour.

⚠️ DO NOT open the oven door during overheating. Stand clear of the appliance.
2

Test temperature sensor

After cooling, test sensor (should be ~1,080 ohms). If sensor is OK, the issue is a stuck relay.

🔩 Multimeter
3

Inspect heating elements

Check both bake and broil elements for visible signs of arcing or burn-through.
4

Replace failed component

If element failed, replace it. If relay is stuck on control board, board replacement is needed.

🔩 LG bake element ($30–$70) 🔩 LG oven control board ($150–$350)

How to Reset Error Code F2

Turn off circuit breaker immediately. Allow full cool-down before inspecting.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

When to Call a Professional

F2 requires professional inspection. A stuck relay is a control board failure that must be repaired by a qualified technician.

Average professional repair cost for this issue: $280–$550

Frequently Asked Questions

Can I keep using my LG Oven when error F2 appears? +

No — stop using the oven right away. F2 is a critical temperature fault, and continuing to run it risks further damage or a safety hazard. Unplug it and resolve the fault before the next cycle.

What most commonly causes F2 on a LG Oven? +

Across reported LG oven repairs, the most frequent is temperature sensor failure causing incorrect readings (40% of cases), heating element relay stuck on control board (35%), then control board failure (15%). Check them in that order before replacing any parts.

F2 keeps coming back after a reset — what should I check next? +

A reset only clears the stored F2 fault; if it returns, the temperature problem is still present. Move on to the physical checks — power off immediately, then test temperature sensor — since the code will reappear until the root cause is resolved. This is an advanced repair involving deeper disassembly or electrical testing.

How much does it cost to fix LG Oven error F2? +

A DIY repair typically runs $0–$70 in parts, versus $280–$550 for a professional service call, so handling it yourself saves around $280. Expect the work to take 1–3 hours.

Which LG Oven models show error F2? +

F2 is documented on LG electric and gas ranges with electronic oven controls, 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.
