My Emerson gets very hot outside after running?

I have an Emerson MWG9111SL microwave. It now gets very hot outside after running for 3 minutes or more. I replaced the thermostat but it still does overheat like before. Cleaned fan and cleaned everything inside. Want to know if this is dangerous and should I get rid of it and buy another one.
