This unit is only 3 years old. Out of nowhere it stopped heating, just spinning. I replaced the heating element, thermostat, thermostat, and fuses and it still won’t heat so I think I didn’t connect a wire inside it. Don’t want to open it back up so I got a new one. When I had it open I cleaned everything really well. Includes 4 prong power supply.

Model is Samsung DVE45T3200W/A3
