What F21, F22, F24, F25 means

On LG electric and gas ranges with a numeric F-code display, the codes F21, F22, F24, and F25 are each listed separately as a steam sensor failure. The control uses these sensors to follow what is happening in a steam or moisture function, and a failure means the reading is lost. The oven may stop that function and show the code. The list does not say which models or which sensor matches each number.

Common causes of F21, F22, F24, F25

A steam sensor reading that is lost
A sensor wire or plug that is loose
A control that is not reading the sensor
A sensor that has stopped responding

✓ One safe check you can try

1. Switch the circuit breaker off for 30 seconds, then switch it back on. 2. Run the function again once. 3. If the same code keeps showing, stop using that function and call us. 4. Wipe away any water around the oven opening once the oven has cooled.

! Why to stop there

The four numbers share one label, so we test the circuits to find which sensor each one belongs to.
A steam sensor can be affected by moisture, and we check for that before replacing it.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F21, F22, F24, F25F21, F22, F24, F25 questions

Do F21, F22, F24, and F25 mean different things?

Each is listed as a steam sensor failure. We test the circuits to find which sensor your number points to. All four numbers carry the same label.

Can the oven still bake?

It may, if only the steam function is affected. We check which functions work before you rely on it. Baking and broiling may still work, and we confirm that on your range.

Will a breaker reset help?

It can clear a one-time reading, so it is worth doing once. If the code returns after the 30-second reset, we test the sensor circuit and its connections.
