What's Happening
The oven temperature went above the safe limit — approximately 590°F during normal baking or 915°F during self-clean. This may be caused by a sensor reading low (making the oven overcompensate), a stuck relay on the control board keeping the element on, or an actual overheat condition.
How to Fix It
Let the oven cool completely. If F2 occurred at a normal baking temperature, the sensor may be reading low or the control board relay is stuck closed. Test the sensor and inspect the control board for welded relay contacts.
Frequently Asked Questions
What does F2 mean on an LG oven?
F2 means the oven exceeded its maximum safe temperature. During baking this is around 590°F, during self-clean around 915°F.
Is an LG oven F2 error dangerous?
The oven's safety system detected and shut it down, so the immediate danger is managed. However, the underlying cause (stuck relay, faulty sensor) needs to be fixed before using the oven again.
What causes an LG oven to overheat?
A welded relay on the control board can keep the heating element running continuously. A sensor reading low can also cause the oven to overshoot its target temperature significantly.
