I have a model#NX58H900WS/AA gas oven. After using the self cleaning feature, the next day the oven would not turn on. Broiler and stove top worked fine. After reading many pages of "oven not heating" and "problems after using self cleaning feature" I came to the conclusion that the lower ignitor was to blame. I ordered part number Maytag 12400035 from Amazon for $25. It is the exact same part! The only difference is the plastic onnector on the end. My Samsung has two individual connectors, the Maytag has one dual connector. That is easily fixed by, turning off the power/breaker, cutting the connector off, and splicing using wire nuts which are supllied in the Maytag part bag. It was a simple fix for me, but I have the tools ( phillips screw driver, wire cutter and strip*er) and expeience doing this kind of stuff. Watch this video it will help. https://www.youtube.com/watch?v=3ucwq1rCHws BTW I got all this information reading posts on this site. So kudos to those above who posted this information. I love the oven, but am disspointed in this known issue. One other thing, if you are desparate and can't wait for the part to arrive, I believe ( but am not sure) the upper ignitor is also the same part as the lower ignitor. So it should be possible to swap them to get the lower ignitor and oven working in a pinch.
