LG Oven F2 Error Code: Over-Temp / Door Latch Fix

What is the LG Oven F2 error?#

F2 on an LG oven means the control sees an over-temperature condition or a door-latch fault — the oven is reading hotter than it was set for, or the self-clean door lock is not behaving. Because uncontrolled heat is involved, treat F2 as a stop-using-it code and let the oven cool. The most common cause is the temperature sensor reading wrong, so the first thing I check is whether the oven actually ran much hotter than the setpoint or simply reported it.

F2 on a LG Oven: likely causes and repair cost#

On a LG Oven, the F2 code signals: door latch / oven over-temp.

Typical professional repair: $160–$340 · Difficulty: hard · usually a technician job

Symptoms that often accompany F2: Oven much hotter than set temperature; Self-clean cycle will not start; Door locked and will not open; Burning smell during normal baking

Technician diagnostic sequence for F2:

1. If the oven is excessively hot, turn off the circuit breaker and allow it to cool completely before investigating — do not open the door if the oven is above 500F
2. Check the oven temperature sensor (RTD probe) mounted inside the oven cavity at the top rear — test resistance: approximately 1080 ohms at room temperature (77F)
3. Inspect the door latch mechanism — if F2 appeared during self-clean, the latch motor may have failed to engage before the oven reached cleaning temperature
4. Check the door latch switch — the oven must detect the door locked before enabling self-clean temperatures above 550F
5. If the oven over-temped (exceeded 590F during bake), the temperature sensor or the control board relay may be stuck, causing continuous heating

Parts a technician may check or replace: Temperature Sensor/RTD Probe; Door Latch Assembly; Control Board — if relay stuck

Field note: LG ProBake Convection ovens position the heating element at the rear rather than the bottom. If F2 triggers as over-temp, the convection fan may have stopped (check fan motor), causing localized overheating at the sensor location near the rear element.

Safety note: If the oven has overheated, do not open the door. Turn off the circuit breaker and allow the oven to cool for at least 2 hours. A stuck heating relay is a fire hazard — do not restore power until the fault is diagnosed.

How to troubleshoot the F2 error yourself#

F2 warrants caution because it can indicate real overheating. Turn the oven off and let it cool completely, then cut power at the breaker for about five minutes and restore it to clear a one-time misread. If F2 followed a self-clean cycle and the door is locked, allow the oven to cool fully so the latch can release before forcing anything. On convection models, a stopped convection fan can cause localized overheating at the sensor, so listen for the fan on a normal bake. Beyond a reset and letting it cool, an owner cannot safely diagnose the sensor or latch. Stop and call a technician if F2 returns: the temperature sensor probe or the door latch assembly has failed, and LG rates this a hard repair that needs metering and disassembly.

Is the LG Oven F2 error worth fixing?#

F2 is generally worth fixing on a functioning oven. A professional repair runs $160–$340 to replace the temperature sensor probe or the door latch assembly, or the control board if a relay stuck — below half the cost of a comparable new range. A sensor or latch job sits under my repair-or-replace line. I only steer toward replacement on an older oven where the over-temp fault joins other failures, since running an oven that overheats is not something to leave unresolved.

LG Oven F2: frequently asked questions#

What does the F2 error mean on a LG Oven?#

F2 means the oven is reading an over-temperature condition or a door-latch fault. The board posts F2 when the measured temperature exceeds the setpoint or the self-clean lock misbehaves.

Is it safe to keep using a LG Oven that shows the F2 error?#

No. F2 can indicate uncontrolled heat, so stop using the oven, let it cool, and have it checked before cooking with it again.

Can I clear the F2 error myself, or do I need a technician?#

You can let the oven cool and try a five-minute power reset. If F2 returns, the temperature sensor or door latch has failed and needs a technician.

How much does it cost to repair the F2 error on a LG Oven?#

A professional F2 repair typically runs $160–$340, covering the temperature sensor probe or door latch assembly, or the control board if a relay stuck.

Which parts usually fail when a oven throws the F2 code?#

The temperature sensor probe is the usual failure, followed by the door latch motor and, less often, a stuck relay on the control board.

Is a LG Oven with the F2 error worth repairing?#

Yes, on most ovens. At $160–$340 the repair is below replacement cost, so unless the range is failing elsewhere, fixing F2 is worthwhile.

Why does temperature sensor issue trigger the F2 error?#

The sensor tells the board the oven temperature. When it reads falsely high or drifts, the board believes the oven is overheating and posts F2 to shut down the heat as a safety measure.
