With the high rate of failure it makes sense that somebody would attempt to make a non OEM version.
If the home warranty thing doesn't cover it I would still open it up and verify that the element or the cutoff has failed. There were a batch of their motors that had failed centrifugal switches and were not sending power over to the element.
So if you end up doing it yourself verify those thermostats or element as the issue.
What's sad is that it's not just Samsung products but across the industry quality has decreased dramatically in the past decade. I repair all brands and there's no one brand I would recommend for all appliances.
