LG Oven f2 error code
The oven temperature sensor is shorted. It sent a bad signal for over a minute during cooking, so the oven stopped heating as protection.
Also shown as: f2, F2
Last updated: October 6, 2026
What causes the f2 error?
- Shorted temperature sensor probe
- Pinched or damaged sensor wiring
- Moisture in the sensor connector
- Failed control board
How to fix LG f2 — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Let the oven cool fully
Turn the oven off and let it cool completely. A shorted sensor can make the oven misread temperature, so do not keep cooking. - Power reset at the breaker
Switch the breaker off for 1 to 2 minutes, then back on, and see if F2 returns. - Inspect the sensor probe
Once cool, look at the probe on the oven's back wall for damage, and check that its mounting looks intact.Safety warning: Make sure the oven is off and cool before inspecting inside.
When to call a technician
- F2 returns after cooling and reset
- The oven overheats or runs wild
- The sensor probe is visibly damaged
- Wiring to the sensor is pinched or burnt
Frequently asked questions
Is F2 the same as the oven overheating?
Not exactly. F2 means the sensor circuit shorted. That bad reading can cause overheating behavior, but the root fault is the sensor.
Can I keep cooking if the oven seems fine?
No. A shorted sensor means the oven is flying blind on temperature, which is unsafe.
What is the difference between F1 and F2?
F1 is an open sensor circuit (broken connection). F2 is a shorted sensor circuit. Both stop the oven from heating.
