How to Troubleshoot & Replace Samsung AP4201898 / DC47-00018A Dryer High Limit Thermostat

I replaced the thermostat, thermal fuse, and heating element. It worked after that. I could tell that the heating element was broken because there was a break in the coils. 

Replaced the heating element, thermostat, thermal fuse assy., and dryer thermistor to cover all possible issues. Using youtube videos as guides the job was very easy and took less than 1hr and half to completely disassemble and reassemble the dryer correctly and it works fine. 

Element worked fine but the fuse and thermostat were faulty 

Longest part of the repair process was me finding screws that I dropped! The videos make it unbelievably easy to find each part and even goes through putting it all back together. Received my parts quickly so my dryer wasn't down for much more than a couple of days. Definitely worth doing myself. 

I watched the videos on the website, found the problem, ordered the parts and installed then according to the video. Now my dryer works again. Thank you. 

Replace thermal fuse and thermostat. 

Replaced heating element coil, thermal fuse, and thermostat. That fixed the problem and dryer began heating like normal. I think both coil and fuse had gone bad. 

Replaced the thermal fuse, thermistor, thermostat and heating element with no luck. I then replaced the motor and it now works fine. 

Before the dryer stopped heating, the auto dry setting wasn't working properly. It would dry the clothes and then keep repeating the cycle and never turn off automatically. I knew this was a hazard, so I stopped using the auto dry setting. I couldn't find any fixes for this particular problem but after it stopped heating, I was able to find information for that problem. I removed the heating element and tested it with a multimeter. It registered fine so I determined that the problem must be with one (or more) of four items: thermistor, thermistat, or two thermal fuses. Each of these parts are relatively inexpensive and I decided to replace all four since I had to take the dryer completely apart anyway. The AppliancePartsPros' videos were extremely helpful. It took about 45 minutes to replace all four parts and now the dryer works perfectly, even the auto dry setting. The hardest part was taking everything apart and keeping track of all the screws. As suggested in the video, I took pictures with my phone along the way so that I could remember what went where. After replacing the parts I cleaned out the dryer before I put it all back together. It was full of lint. I'm not sure if this contributed to the issue, but I'm sure it didn't help any. Thanks AppliancePartsPros, you saved me a bundle!
