I'll be happy to look into this.
What's the model number?
We purchased a smooth top, convection Samsung range , with delivery on March 22 - nothing but problems with the oven. We even had a tech her and he thought he had adjusted it. Well, it takes about 35-45 minutes to preheat, if I change a pan of cookies, it drops between 25 to 50 degrees and it takes 10 to 15 minutes, or more, to get to temps again. All this was not explained when we got the stove, nor is it in the documentation. I am at a loss as what to do since it cost us a lot of money, and now, since we have been trying to work with the store, it is over 30days. I contacted Samsung, and got told to check the page in the manual to adjust the temp (which was out by 15 degrees by the way), which had already been done. I am so frustrated and I needed to vent. Any help would be appreciated.
