I too am shocked at the poor design and lack of attention to correcting this problem with the most important need to operate a range of this caliber!  I specifically followed the user guide prior to broiling only to realize too late, that these knobs are a flimsy foil covered plastic and melted.  After much time and research, I was "offered" a one time price to replace the knobs not realizing that the circuit board behind them was also damaged.  Now after a power outage, I am unable to reset the oven in order to bake! Will NEVER purchase a Kenmore product again.
