Product review (3 stars): Danger - Cracked Knobs and Other Hazards
We've had this stove in place for 2.5 years now and are very pleased with all the features and ease of use.

One important caveat, however.

We noted a strong odor of LP gas two nights ago and discovered that unignited LPG was pouring from the right front burner.  The shaft on the knob had cracked, allowing the knob to turn without actually adjusting gas flow.  While it appeared that the knob was in the 'Off' position, it was actually in the Power Boil (full on) position.

Also, one can turn the knob on the center burner, with the griddle in place, past the point where the pezio igniters kick on and not realize the burner hasn't ignited.

Price on the GE website for a replacement knob is $60!  Lots of bucks for a piece of plastic.

Be Careful!
