Let me first say that I am a chef, so I put this stove through every test I could, but I cook *normal* food on my stove.
Let me say second, that I had the first stove (same model) sent back to the store after the first round of problems.
The largest burner (front left) drops it's temperature without warning or indication. The temperature just dives, and this makes sauteeing and frying extremely difficult - I have ruined many dishes because of soggy crusts and rubbery filets.
The other main problem with stove #1 was the noise. When I boiled water with one burner and cooked something else on other burner, the stovetop would make high-pitched screeching noises that sent me out of the kitchen (apparently, I'm part dog). I found it difficult to cook from the other room, so I basically could only use the stove as a glorified hot plate, only using one burner at a time...
Well, my replacement range (Samsung Induction FTQ307) did well for a few months, then the problems have returned. The large burner kicks out after using it on #7, and the burners are making horrible squealing noises, just like before.
New problems!: The cooktop randomly changes the level at which I am cooking without warning. For example, if I have the back burner going on level 8, it lowers itself to 5.5 for no reason - no spillovers, nothing. It doesn't even beep when it does it, so I have no idea that the burner has been lowered. I thought my husband was playing a joke on me, but he swears he didn't do it, and it's done it when I'm alone.
The oven beeps when temperature set is achieved, but the oven is 100+ degrees cooler than it says. It takes an inordinate amount of time for the oven to heat up. I cannot bake bread anymore as the oven doesn't recover fast enough when the door is opened.
I cannot use more than 1 burner when the oven is being used. If I use a second burner, the power drops to both burners (not linked to each other), and the oven temp drops.
I cannot use more than 2 burners at the same time. I get too much noise feedback, and the burners cannot sustain the desired temperatures.
I want to send Samsung a message that I feel that they are using the consumer as a test lab, and allowing us pay $2000 for a stove that has real defects in both design and execution.
The arrangement of the burners is ridiculous. The back-right burner is so close to the controls, that you can't set oven temps or use the timer without moving the pot. And when that pot is boiling, it sends condensation into the control panel. Hmm, I wonder how long before THAT starts to malfunction?
When you put a burner on level 2 or 3, I expect to be able to cook something at a steady temperature. Nope. The power cycles through in 27-30 second intervals so that the pot is either bubbling or doing nothing. There is not a way to just have something cook on low. Forget trying to make a creme anglaise without risking it breaking because the heat is not controlled and even...this is what induction is supposed to overcome with radiant heat electric. Induction is supposed to surpass gas in it's ability to adjust heat. Nope. Not with this stove.
The repair man said to avoid using the self clean function as it really messes with the temperature sensors (which is what sets the burner/oven temps) I have never used the self clean nor the steam function (needless use of electricity - clean your oven after each use and you won't need to incinerate food drips). He said he's seen most of the Samsung ranges have problems after self-clean is used.
On the cosmetic part of what is wrong is that when cleaning the oven door by hand, both inside and out, there is a problem that drips end up between the glass window, and you have permanent drips! Second problem is when you put a towel on the handle, the way they designed the oven vents, there is a real danger of cutting your fingers when grasping the handle or replacing a towel. I've nicked the tips of my fingers several times, and it's in such a way, that you can't "train" yourself to not do it.
If you can't make a product well, just don't make it, and leave it to those that can. Stick to TV's and phones, Samsung.
Addendum:
