Product review (5 stars): The perfect part that I needed.
The big burner on our glass-top GE stove stopped functioning a year or so ago.  The outer ring would still light, but not the inner one.  I generally am loathe to mess with appliances, so I let it go for a long time.  Like many others, I priced the part on the GE website and found that it was roughly half as much here, via Amazon.

The part arrived packaged very well - its box within a much larger box and cushioned with wadded paper.

The reason I decided to give this a shot was because I checked out some instructional videos on YouTube and it looked to be simple enough.  Installing it was relatively easy...I had my teenaged son assist.  Unlike the videos I watched, though, I had to unfasten *all* of our burners to get the one in question free because of the "bridge burner" on the left side.  That done, it was easily removed.  I, too, lost one of the springs down inside the appliance when removing the burner (like another reviewer or two), but it was easy enough to retrieve by removing the drawer underneath the oven.  The electrical connections popped off with pliers without a problem.  What I didn't realize, at first, was that the new unit did not come with the clip assemblies, which are screwed to the [apparently, aluminum] pan.  The holes are all pre-drilled, so all you have to do is place the clips at the correctly numbered holes (the numbering on the new part matched that of the old).

We put the stove back together, kicked on the power, and it lit right up.  We no longer have to use the bridge burner for large pots.  Yay.
