Product review (4 stars): Worked perfectly.
Classic symptom, easily diagnosed with the help of YouTube.

Laundry was piling up already (towels and sheets mainly) so I paid extra for fast shipping. It came USPS priority mail, in a flat rate envelope - with a box inside that - at the "soon" end of the promised delivery window. No complaints there.

The guys on YouTube make everything look easy - and it *almost* is. In my case, the provided self-tapping screws for the new thermostat / cut-off wouldn't thread into the holes. After swearing and sweating way too much for such a simple job, I swapped them for ones that secure the back cover, and those worked fine.

Will update this review if the unit fails. But so far it's been great. Would be nice if the manufacturer didn't try to save $0.03 in the original build and used parts that would last - but I know that's wishful thinking.
