Never repaired a dryer before not really good with testing electrical components so I took the four most common failure parts and purchased. Went step-by-step remembered all the screws locations. A Phillips screwdriver was all I needed parts were super easy to find complete project disassembly replace parts reassembly approximately an hour turned it on hope for the best. I did this project with my son I wanted him to see how things work and you can fix things yourself without calling a repair man. Hit the start cycle and it ran just fine. I would recommend tackling this project to anyone with medium skills
