FTQ386LWUX (XAA) Samsung Range - Overview

My barely 4 year old Samsung range/oven began not heating consistently. Even though it said 350, for example, we had to increase to 465 to get it to bake. Thought it was the temperature sensor. Ordered and installed new one easily. That didn't solve the problem. So, rather than throw more money at parts that may not have resolved the issue, I got a new Amana range. Samsung appliances go to my 'do not buy' list along with LG!

ordered the temp sensor for a standard complaint, new sensor was the correct part ordered, however, once the old sensor was removed, I ohm'd the original and the new part. Both were 1080, checked wiring, checked gas burner, checked line voltage. Searched other part prices, found Samsung to be a not desirable product to own. This non repair was to help my neighbor who lives on a fixed income. Checked oven temp with the oven at 350 f setting, oven was 223 f. Set oven to 465 f and fount the oven at 353 f. I wanted to return the part but she insisted I install it anyway and found the oven doing the same thing. She did not want to throw more money at a 4 year old range. Will use it as it is but will buy a cheap oven temp gauge. Samsung sucks.
