We purchased this slide-in induction range, model NE63T8951SS, about a year ago. This was priced as a top-of-the-line oven, around $4,000, and was a splurge given how happy we had been with our previous Samsung FlexDuo oven. We thought we would be thrilled to have an oven that reliable combined with an induction cooktop. Fast-forward a year...
The induction cooktop is great. The oven is a disaster:
1. At the completion of the preheat cycle, when the oven beeps and the front panel shows the target temperature has been attained ... the oven is actually nowhere near that temperature. Ambient thermometer readings consistently show that it takes 8-10 minutes AFTER the oven beeps for the internal temp to reach the target.
2. The oven is extraordinarily slow to regain target temperature if the oven is opened. Yes, we know - opening the oven will drop the temp. But you have to put food in - therefore, the oven has to be opened! We have measured up to a 45 minute delay after a single opening for the oven to regain the 50-60 degrees it loses when it is opened. And don't get me started on the fallacy of trying to bake cookies or anything that requires pans to be turned or swapped between higher and lower racks - again, temperature plummets and takes forever to recover. We made a Christmas cookie recipe a few weeks ago that called for a 8-minute cook time, they took over 30 minutes in this oven.
We called support and were advised that we should use the calibration feature to adjust the oven temperature and that Samsung wouldn't send a technician until we had done that. We played along and spent a couple months running tests and adjusting the calibration temperature (30 minutes per test, top oven, bottom oven, full oven, normal and convection ... dozens upon dozens of tests).
After still getting terrible results we opened a support ticket under warranty, and were astounded that:
* the technician was rude about our explanation of the problem (his response, with a smirk, was "well I've never heard of anything like that, you're not measuring it correctly").
* the technician refused to consider our report that the preheat cycle was not reaching temperature. His response when I asked why the oven wasn't at 350 degrees when the front panel was at 350 degrees was that the oven "would never be at the temperature the front panel says, it's a cycle, up and down, up to 50 degrees above or below that temperature."
* the technician refused to look at the pages of test cycles and temperature readings I had captured over the prior few months. He ran one test of oven heating and said the oven was working fine, packed up and left.
This oven is the worst I've ever owned. In 30 years of cooking/baking I have never been driven to the point where I will buy ambient temperature thermometers, I have never had to calibrate my oven and I have never had such wildly inconsistent performance. And this oven was more than twice the price of the FlexDuo oven that we replaced - an oven that was rock-solid reliable for over seven years.
Will Samsung do anything about this issue? Based on our experience with the technician, I doubt it. Will we buy more Samsung products in the future? Nope - our Samsung fridge was just replaced with another brand. And our $4,000 top-of-the-line oven is looking like a throwaway.
My NSI6DG9500MTAA is not as bad as yours, but it does the same thing. I have to stand there and constantly change the temp. It will get to where it should be and 10 minutes later be 20 degrees lower without opening it at all. It is worse at high temps (400 +). Air fryer is horrible. I have yet to try and get it fixed. Sounds like it will be impossible. I am with you. Never buying Samsung appliances again and may drop Samsung for phone and tablet at replacement time.
