I cleaned out a lot of lint build up from dryer. I learned about the safety cut off that are non-resetable and thermal fuse. I replaced the heating element, but not the problem. I don't know how to trouble shoot the problem. I am buying a meter tomorrow, so I can do this right. I need to know what readings, I should get on each part. So, I know what part is bad. Please advise any help would be greatly appreciated.
