Dryer Control Lock
Some models offer a control lock feature. You can lock the controls to prevent any selections from being made. Or you can lock the controls after you have started a cycle. Children cannot accidentally start the dryer by touching buttons with this option selected.
To lock and unlock the dryer controls:
Press and hold the Extended Tumble and - (minus) buttons for 3 seconds. The control lock icon will flash while locking/unlocking, stay on when locked, and turn off when unlocked. NOTE: The Power button can still be used when the machine is locked.
