Product review (1 stars): Nothing But Trouble
I purchased this range in March 2014 after reading all the awesome reviews.  I chose this model because of the flex duo ovens and the fact that this seemed to be the only brand where BOTH upper and lower ovens were convection (i.e., was not available in the double ranges of other manufacturers).  I really wanted to love this range and had such high hopes, but sadly after a few months things went downhill and I've encountered a number of problems as follows:  both the upper and lower ovens cannot maintain the set degrees...e.g., I set the oven at 350, but according to my freestanding oven thermometer (which the service technician verified), the oven runs either at 550 (lots of burned food) or 275 (undercooked food)...very frustrating.  I also have problems with the burners...one actually flashed on and off (i.e., red and black) nonstop every two seconds.  Ive had a glass top cooktop for 20 years so I completely understand how the mechanism needs to cycle on and off to maintain the temperature; but this range is totally not normal.  It's extremely hard to regulate the burner temperature (i.e., you set it on low, but it still burns hot, etc.).  I've had 7 different repair tickets and the techs have replaced both oven thermostats, all the cooktop regulators, the bridge burner assembly, the main board PCB, the sub PCB board, the board behind the control panel, etc.  What a nightmare.  At this point, I'm sick of Samsung, sick of the various technicians (some were wonderful, others told me that it's "normal" for a 350 oven to run at 550, and it's "normal" to have to jiggle the range knobs to keep the burners on "high"), and sick that I spent almost $2k on a range that continues to disappoint.  I should have kept my prior 20-year old glass top range. Again, I very much wanted to love this range, but unfortunately have had nothing but trouble.  Some of the techs have told me that they've encountered the same problems on others and blamed it on the fact that this is a relatively new Samsung model....sigh. Don't be like me and ignore the bad reviews thinking that they were posted from atypical disgruntled customers.
