Thanks for using Just Answer I'm John I will help you with the problem.
Theres no reset but it does have a thermal fuse that can fail.
Please send me the model number I will look at the dryer and show you where it is .
The fuse is the number 10 its located on the blower if it fails the dryer wont start.
Your very welcome also check the venting to the outside if thats blocked up it will cause it to fail as well.
Thanks and God Bless.
