The front control knobs depress and rotate upon inadvertent contact, turning on the range accidently! I experienced top burners being on by accident three times simply by brushing against the front of the stove while reaching into a cupboard. The LOCK feature is critical; however, if not set, danger!! This resulted in a recent kitchen fire on top of the range! Company was here; pizza baked; lock not set; a guest placed a potholder with silicone backing on the stove top then inadvertently brushed against a burner knob, turning it on.  Suddenly, the potholder was in flames and the kitchen/dining area filled with smoke!   I found other consumer reviews with the same concern regarding LC's LSEL6335. PLEASE take this concern seriously for the sake of your customers' safety.  Thank you!
