When we first purchased the product, the first product came as a faulty unit.  It took technicians many trips to determine that we needed a replacement unit, which is the current one.  This unit worked fine until March this year.  The two left side burner will not remain on for longer than 3 seconds.  We tried to reset the cooktop by turning off/on the breaker.  It helped twice.  The unit was under Geek Squad warranty at that time.  We should have called service!!  Now, the protection plan just passed the 5 year mark.  The breaker reset strategy will not reset this problem.  For cooktop with this price range, it needs to be reliable.  My previous Jenn Air range lasted 17 years!!
