Product review (1 stars): Broken burner after 14 months of purchase, stay away!
I purchased this cooktop last January.  It is only under warranty for one year from purchase.  Well 14 months later I was cooking with middle burner, the knob wouldn't turn, got it loose a little and the burner will not shut off with the knob off.  So the gas is continuously coming out of the burner with the knob off.
I called Frigidaire and basically no help, they said it's only covered a year but they will pay for the part it will need.  The part company has to be a authorized Frigidaire repairer.  They can't find one in my area.  So basically I'm stuck with a stovetop that the middle burner is constantly on which is a complete hazard.  I had to shut the gas off below.
I an NOT HAPPY considering this cooktop is only 14 months old.
I would look for another cooktop that doesn't break after 14 months!!
