I love the ikea Nutid cooktop however this is the forth time I have had a technician out to repair it.  The first time it stopped working I brought it back to the store and they replaced it.  I still have 2.5 years left on the warranty, I just hope all the bugs get fixed before the warranty is up:(.  It won't be cost effective to fix it otherwise.

The repair person told me that all of the electronics have been updated due to complaints.  So I am keeping my fingers crossed that it will be fixed for good.
