Lg Oven Error Code: F3

When an LG oven displays the F3 error code it indicates that the keypad control is shorting out. This is usually caused somewhere along the wire harness leading up to the buttons, but it can also be caused by the keypad control itself.

The issue can be reset by restarting the oven but once the problem has started appearing it might do so more frequently. If the error isn’t reset by restarting the oven or if it reappears soon thereafter, you’ll need to replace the keypad assembly.

The keypad assembly can be purchased for $50-100, depending on the model. (This might vary depending on where you are)
