Product review (1 stars): No need to buy replacement knobs!!!
I refused to pay the insanely high prices JennAir wanted to replace my cheap dollar store quality knobs with more cheap dollar store quality knobs.  I'm a nail tech with many years of experience.  I rebuilt them with acrylic and they work great!  Much, much stronger than before.  My advice is to find an American run salon with a good acrylic tech.  Why would you give JennAir more of your money after you already spent so much on the worthless pile of junk?  The way I look at it, if it was a high quality range, wouldn't you think they would use high quality parts? Any other brand you can buy universal replacement knobs at the hardware store.  Not JennAir.  And don't get me started on replacement light bulbs for the oven....
