Hello

"F -24" error code means the keys on the control panel were pushed or touched for longer than 60 seconds. Leaning against the oven or hanging objects in front of the controls can cause these error codes to appear. To fix this,turn the oven off and wait three minutes before turning it on again.

If the code keeps displaying then the problem is that you have a "Touch Input Key Stuck" it could be that the touch pad got weak from constant pressing or just made inferior.. Now with that in mind the fix is to replace the power relay board and the touch pad. You should start with replacing the touch panel first. This is probably the more likely suspect. Then if that don't work replace the power relay board.This is not a cheap fix.

To get your model number usually if you open the oven and look in the top between the grill, right above the door you can see a tag with the model number. You will need a flashlight and good eyes.

To stop the beeping,you have to disconnect the power to the oven.
