I used the oven self clean function 13 months after purchasing  for the 1st time after Thanksgiving and three  cooktop elements were damaged.  Two infinity switches and one cooktop element were damaged after the four hour self clean process. The warmer element stopped working completely and you could fry hashbrowns on the lowest temperature on the right front element.  Service fees and replacement parts totaled 1/2 the cost of the unit.   Any other time I would have trashed the appliance and purchased a new one.
