Product review (5 stars): An excellent replacement part.
I have a 4 burner kenmore stop top with center griddle from the early 1980s.  It's an excellent OLD stainless steel cooktop that I was given by my father when he remodeled his kitchen. I had been using the stove for about 10 years when the contacts finally wore out on the front right corner unit.

I ordered this part at quite a discount compared to what sears wanted for the same part.  It shipped quickly and I installed the part within minutes of arrival.

Keep in mind, my mechanical and electrical skills are above average, but I think anyone with common sense could replace one of these.  Turn off the circuit breaker before performing the service, for safety's sake.

The contacts fit neatly with the burner unit, I've been using this for about 6 months now without issue.  The wires were plenty long enough to reach the controls, the blade type connectors fit perfectly.  I used some zipties to make a clean installation.  I'm very happy with this repair part.

A new stovetop?  $500 or more.  I fixed for about $5.  Since stainless never really goes bad, I don't think I'll ever have to replace this stovetop.  God, I love the internet...
