Product review (5 stars): Jenn-Air replacement burner
I purchased this to replace the original one on my almost 23 year old Jenn Air Electric cooktop.  The original ones were still working but were getting old and I wanted a fresh, clean look.  This replacement fits perfectly.  Installation is as easy as plugging it in.  It is reasonably priced, too, through Amazon.  It heated up instantly. Note: The burner pictured only has three circles of coil which I did not notice until I had placed the order.  I was afraid that the heating of the element would not be what I was used to.  The one I received, however, had five...exactly like my original one so the distribution of the heat will be the same.
