I vacuumed out all of the lint from every crack and crevice of my dryer. It runs a lot hotter now. Yours sounds like it is more hot than is normal. I'm not sure if that is bad or not. But I do know that your dryer will run hotter after you clean the lint out.
If you don't smell anything, then there's probably no problem. But you should probably use your multimeter to check to make sure that everything tests correctly as to amps/watts/ohms, etc.
