Samsung Dryer NOT HEATING

A month ago the Samsung Dryer stop heating. I changed the element and still not working. I changed all the other fuses (thermostat, thermal fuse) and it worked for a few minutes and then stop blowing hot air. I tested the continuity of the fuse and found that the new thermal fuse I changed has no continuity, I order a 2nd thermal fuse and changed it. The dryer start working and blowing hot air, after a few minutes it stop blowing hot air and it was blowing only cold air. I checked again and the thermal fuse has not continuity. What could cause the problem?. Dryer is a 1-1/2 years old. It is installed in a 2 month new house.
