+1. Our Samsung dryer did the same thing a few years ago. Ordered a new thermostat online ($50-ish), unplugged it, removed a few screws, unplugged the old thermostat, then switched it out and put everything back together. The whole process took maybe an hour.
If you can build ikea furniture, you can replace a dryer thermostat.
A few years after that, I did the control board. Have also replaced the start capacitor in our HVAC, and the pump in our dishwasher. Dishwasher was by far the hardest due to getting it pulled out of the cabinets and the plastic parts breaking easily.
